List of fictional diseases

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.

This article is a list of fictional diseases — nonexistent medical conditions which appear in fiction where they have a major plot or thematic importance. They may be fictional psychological disorders, magical, from mythological or fantasy settings, have evolved naturally, been engineered artificially (most often created as biological weapons), or be any illness that came forth from the (ab)use of technology.

Items in this list are followed by a brief description of symptoms and other details.

In literature

Name	Source	Symptoms
Andromeda Strain also known as La Linea Verde de Muerte; The Green Line of Death.	Andromeda StrainThe Andromeda Strain by Michael Crichton	A deadly, green, crystalline, extraterrestrial agent of indeterminate origin. It erodes the vessel walls of the circulatory system, causing death by either triggering the body's coagulation response (resulting in the entire system clotting in a few seconds), or by cerebral hematomas (accompanied by dementia) if clotting is prevented. It evolves at a rapid rate, is spread by airborne transmission, and is extremely contagious. However, it only functions within a very narrow pH range, and cannot survive in a human body if that human's blood chemistry is too alkaline or too acidic.
Atlantis Complex	Artemis Fowl: The Atlantis Complex by Eoin Colfer	A psychosis common in guilt ridden fairies, but is contracted by Artemis by his dabbling in fairy magic. The symptoms include obsessive compulsive behavior, paranoia, multiple personality disorder, and in his case professing his love to Holly Short.
Bazi Plague	The Gor Series by John Norman	Bazi plague is a deadly, rapidly spreading disease with no known cure. Its symptoms include pustules which appear all over the body, and a yellowing of the whites of the eyes.
Black Trump Virus	Wild Cards by George R. R. MartinWild Cards by George R. R. Martin	The Black Trump virus is a variant of Xenovirus Takis-B. Rather than a cure, this retrovirus was designed to kill aces, jokers, latents, and wild card carriers. Dr. Tachyon's original Trump virus was designed to turn wild carders back into nats a slang term for naturals, those who do not carry Xenovirus Takis-A in their system.
Bloodfire	Blood Nation	A virus that gestated in wolves two thousand years ago. The first to be infected was Genghis Khan. It causes the symptoms usually associated with vampirism, photosensitivity and invincibility. The entire nation of Russia is infected, except for a few feral children. The virus can cause extreme mutation, for example the snake's tail present in the Khan's head scientist.
Brainpox "Cobra"	The Cobra Event	A genetically engineered recombinant virus made from the nuclear polyhedrosis virus, the rhinovirus, and smallpox. It causes nightmares, fever, chills, runny nose, encephalitis (brain swelling), and herpes-like boils in the mouth and genitals, followed by a short period of aggression and autocannibalism preceding death. Used as a bioterror weapon.
Buscard's Murrain aka Wormword	"Entry Taken from a Medical Encyclopaedia" by China Miéville	An echolalia-like disease in which a specific pronunciation of a certain word—the "wormword"—leads to fatally degenerative cognitive ability as a result of an encephalopathy. Buscard's Murrain is infectious, as the afflicted desire to hear others pronounce the wormword.
Captain Trips ("Superflu", "tube neck", and "project blue")	StandThe Stand by Stephen King	A deadly, flu-based virus. Created as a biological weapon codenamed Blue. Causes a lethally high fever and is highly contagious. It is deadly because as the body fights off the disease, it mutates into different strains of influenza, making immunity next to impossible.
Clone-Killing Nanovirus	Star Wars Republic Commando: Hard Contact by Karen Traviss	A nanovirus developed by the Confederacy of Independent Systems designed specifically to kill the clones of Jango Fett. Its creator, Ovolot Qail Uthan, is captured by Republic Commandos before her research is complete, however. In later books in the series, it is revealed (though not to any of the main characters, but to the reader through both Palpatine's and Dr. Uthan's private journals), Chancellor Palpatine secretly chooses not to completely destroy all evidence or research of the virus, but rather opts to hold onto it as a back-up plan, should the clone army ever be turned against him.
Codon Zero	Codon Zero by Jim Hendee	Codon Zero is the name of the nucleotide sequence that encodes a plague that infects only Arabs and Jews which share a common genetic ancestry that began millennia ago. A secretive group of geneticists has developed this deadly disease (dubbed the Middle East Plague by The New York Times) to force the leaders of the Middle East into a binding peace. The geneticists claim that the afflicted will develop symptoms of dehydration, thirst, headache, dizziness and a decrease in appetite, and although they will feel deathly ill indefinitely, it should not prove fatal.
Collins' Syndrome	The Legend of Deathwalker by David Gemmell	A mutating disease that often starts with pain and sensitivity in the victims nipples, then forms a temporary tumor in the brain as it feeds upon the genetic material of the brain cells, sapping away the victims critical thinking skills and intelligence, once it reaches its critical density, the tumor disbands into the bloodstream, the virus going into a form of hibernation, leaving its victim in a state of near absolute uselessness. Once the virus detects that it has entered a new host due to differences in protein markers of the victims cells, the process begins again.
Cooties	Various	A term used by children in the USA, with varied meaning. "Cooties" generally refers to an invisible germ, bug, or microscopic monster, transferred by skin to skin contact, usually with a member of the opposite sex.
Dar-Kosis	The Gor Series by John Norman	Dar-kosis is a virulent, horrible, wasting disease and is similar in many ways to leprosy. It is taught by the Initiates (who claim to be the voice of the Priest-Kings of Gor) that Dar-Kosis is a holy disease.
Descolada	Speaker for the Dead by Orson Scott Card	A quasi-conscious self-modifying organism capable of infecting any form of life. "Descolada" is also the Portuguese word for "unglued". In the context of the book, this refers to the Descolada virus's effects: it breaks the link of the DNA double helix (ungluing it) and induces mutations.
Diseasemaker's Croup	Fragile Things by Neil Gaiman	A disorder 'afflicting those who habitually and pathologically catalogue and construct diseases.' It is characterized by increasingly nonsensical speech and writing patterns and an obsessive insistence on trying to repeat previous statements out of context.
Dragon Pox	The Harry Potter Series by J.K. Rowling	Dragon pox is a potentially fatal contagious disease that occurs in wizards and witches. Its symptoms are presumably similar to Muggle illnesses like smallpox and chicken pox. However, in addition to leaving the victim's skin pockmarked, dragon pox causes a lasting greenish tinge. Simpler cases present with a green-and-purple rash between the toes and sparks coming out of the nostrils when the patient sneezes. Elderly patients are apparently more susceptible to dragon pox than younger ones. Gunhilda of Gorsemoor developed a cure for dragon pox, but the disease has not been completely eradicated, as is evidenced by the fact that it is still treated by the Magical Bugs ward at St. Mungo's Hospital.
Dryditch Fever	Salamandastron by Brian Jacques	A deadly disease causing weakness, hot flashes, chills, and dizziness. The victim is usually bedridden until eventual death. The only known cure are Flowers of Icetor boiled in spring water.
Fire-Us (Sounds like "Virus")	Fire-Us series	A viral infection that infects extremely fast and only infects those that produce sex hormones (i.e. those after puberty and women before menopause) or are taking medicine that include similar hormones. It was released by the President of the United States of America to start the world over, killing almost all adults within 2 weeks. As a result, children were left to fend for themselves, most of whom failed. Once all the targets of the virus were gone, it died out.
Foul-Drought	Heir of Mistmantle by M. I. McAllisterThe Heir of Mistmantle by M. I. McAllister	Disease caused from drinking poisoned water. Animals who have it will have pain, blurry sight and some will eventually die.
Gray DeathThe Gray Death	Gail Carson Levine's The Two Princesses of Bamarre	Disease created from the noxious gas from the defeated dragon Yune's stomach. It comes on with no warning and is not contagious. There are three stages of the disease. The first stage is the weakness, and it can last anywhere from a week to six months. The second stage is the sleeping, and it always lasts nine days. The last stage is fever, and it always lasts three days. At the end of the fever stage, the victim will die. The only cure is water sent down from the fairies' Mount Ziriat. The cure will only be discovered when cowards find courage and rain falls over all Bamarre.
DX	The Lost World by Michael Crichton	An unknown prion dubbed "DX" by scientists on Isla Sorna. It is similar to mad cow disease and was the result of feeding ground-up sheep to carnivorous dinosaurs. DX increased the mortality rate of newborn dinosaurs and is eventually fatal to adult dinosaurs. In order to combat DX, InGen scientists released animals into the wild of Isla Sorna. The prion initially infected carnivorous dinosaurs such as velociraptors and procompsognathus, which would then spread the disease to herbivores such as apatosaurus, and the apatosaur carcasses would be eaten by compys, which would then spread the disease to other carcasses, and the cycle would repeat. Ian Malcolm said at the end of the novel that, because of the imbalance of carnivores and herbivores due to DX, the dinosaurs were doomed to die out.
Ebola Gulf A	DC Comics	Also known as "the Clench", due to the victims clenching their stomachs, Ebola Gulf is an evolved form of the ebola virus created by the terrorist mastermind Ra's Al Ghul after he consulted the Wheel of Plagues.
Greyscale	A Song of Ice and Fire	Greyscale is a typically nonfatal disease in the Song of Ice and Fire series. It is first introduced in Stannis Baratheon's daughter Shireen. When it infects children, greyscale generally leaves children malformed and disabled but alive. However, in A Dance with Dragons, it is revealed to be generally fatal to adults. The disease is contracted by touch and slowly turns the flesh (small patches in children and the entire body in adults) of the victim to stone. It is said that the disease also drives its adult victims insane.
Ghancroid, fake disease	Andromeda StrainMany novels/movies by authors	A fake disease, crystalline, extraterrestrial fatal genetic disease.
Herod's Flu (SHEVA)	Darwin's Radio by Greg Bear	A contagious, sexually transmitted human endogenous retrovirus (HERV) that causes flu-like symptoms and ultimately causes miscarriage of pregnancies. Though treated as a public health crisis by the Centers for Disease Control and Prevention and World Health Organization, the virus is later revealed to be a mechanism which causes rapid speciation and accelerates evolution.
Great Plague	The Lord of the Rings by J.R.R. Tolkien	A mysterious disease which swept down through every single kingdom of Middle-earth during the mid 1600s of the Third Age of the Sun. The Plague's origins are unknown except it was possibly contracted from the Corsairs who attacked Gondor in Third Age 1634, two years before the Plague occurred. The Plague was 90% fatal for nearly all inhabitants of Middle-earth, especially in Gondor and the North.
Harlequin	Harlequin Rex by Owen Marshall	A progressive and fatal neurological disease which causes an re-awakening of primordial senses and behaviors, set in near-future Earth.
I-Pollen Degenerative Disorder	DC Comics Transmetropolitan	The hero Spider Jerusalem has I-Pollen Degenerative Disorder, a disease he gained as a result of coming into contact with Information Pollen, pollen used to transmit information. In 98% of the cases, the disease will cause the victim to lose all motor and cognitive skills. It is comparable to Alzheimer's and Parkinson's disease.
Kellis-Amberlee	Feed by Mira Grant	A spontaneous combination of two man-made viruses that exists in a 'reservoir condition' state without ill effects until the host's death, when any host over approximately 40 pounds undergoes virus amplification and becomes a zombie.
Legacy Virus	Marvel Multiverse	A disease that targets only mutants, causing genetic and biological degradation and eventual death; shortly before death, the virus' effects will cause a violent, uncontrolled flare-up of the victim's superhuman abilities.
Life-Eater Virus	Warhammer 40,000 novels	The Life-eater virus is a form of necrotizing fasciitis that causes all biological matter to break down into its component parts, releasing toxic, flammable gas that can be ignited with a single explosion. The virus eats itself when there is nothing else to attack. It is quite effective against Tyrranids. In the short-story anthology Planetkill, an updated strain goes after the soul, turning the population into zombies, created by a Techpriest inhabited by a daemonic Unclean One.
Krytos virus	Star Wars Expanded Universe"Star Wars Expanded Universe"	The Krytos virus was a deadly and highly contagious virus that only attacked non-human species. It could spread via a number of avenues, including by water supplies and by air. The virus often killed its host in less than two weeks, resulting in a painful death.
Maternal Death Syndrome (MDS)	Testament of Jessie Lamb by Jane RogersThe Testament of Jessie Lamb by Jane Rogers	Latent in everyone and triggered upon pregnancy, it causes rapid progressive brain degeneration and is invariably fatal to both mother and child.
Middle East Plague	Codon Zero by Jim Hendee	(See Codon Zero, above.)
Red DeathThe Red Death	Masque of the Red Death by Edgar Allan Poe"The Masque of the Red Death" by Edgar Allan Poe	Victims bleed from their pores before eventually dying. See also: Scarlet Plague.
RipleyThe Ripley	Dreamcatcher by Stephen King	An alien parasitoid macrovirus. The adult aliens resemble deformed potato beings with legs, while the younger aliens — nicknamed "shit-weasels" because they can be created in a host organism's stomach and escape by eating their host's body between the stomach and anus — are legless, smaller versions of the adult alien. Both adult and young aliens have a mouth consisting of a slit on the underside of the head that goes down the length of the worm. The lips separate to reveal hundreds of teeth that can bite through steel.
Neurodermatitis	Dark Benediction (1951) by Walter Miller Jr.	A pathogen causing rapid nervous system evolution and development of new sensory organs, which causes synesthetic psychosis in unprepared hosts. Sent to Earth by an alien race living in symbiosis with it, in the hopes of furthering other races' advance. Designed for controlled delivery, it is turned into a plague by a curious retriever's cutting the vessel with an hacksaw.
Ratititis	Roald Dahl's Boy	A fictional disease invented by Roald Dahl's friend Thwaites during their schooldays in Llandaff. Thwaites made this up to amuse Roald and the other friends, but he says his dad told him about the disease, which is apparently contracted from eating liquorice bootlaces. Thwaites says that the bootlaces actually have rat's blood rather than licquorice, and they are done this way by rat-catchers bringing their rats to the sweet factory where they pound the rats into a paste, then mash it up to form licquorice bootlaces. Thwaites told Roald and his friends never to eat them, because if they did, a rat's tail would burst out of their buttocks and their teeth would turn into fangs. Only Roald and his friends saw the joke; Thwaites took it with deadpan humour.
Salt Plague	Spiritwalker Trilogy by Kate Elliott	Disease which feeds on the salt in its host's body. The host eventually loses their humanity and becomes violently hungry, seeking the salty blood of others. The plague is spread by its victim's bites.
Scarlet Plague	Scarlet Plague by Jack LondonThe Scarlet Plague by Jack London	This 1912 novella, also known as the Scarlet Death, is a work of post-apocalyptic fiction treating the world after civilization has been destroyed by this fictional disease.
Shame	The Hitchhiker's Guide to the Galaxy by Douglas Adams	Mentioned as being "still a terminal disease in some parts of the Galaxy," this disease seems rife amongst the population of Betelgeuse 5, the fifth planet of the sun Betelgeuse. It killed off the father of Ford Prefect when he was so ashamed that Ford could not say his birth name, "Ix", and this embarrassed Ford and resulted in him being mocked during school.
Shiva	Rainbow Six by Tom Clancy	A artificial virus created by the means of biotechnology and based upon the Ebola agent to help the aim of a group of eco-terrorists in annihilating mankind.
Snow Crash	Snow Crash by Neal Stephenson	A dangerous drug which is both a computer virus capable of infecting the brains of unwary hackers in the Metaverse and a mind-altering virus distributed by a network of Pentecostal churches via its infrastructure and belief system. Both forms cause glossolalia, and the computer virus form appears as a snowy pattern of pixels.]
Spattergroit	Harry Potter and the Order of the Phoenix and Harry Potter and the Deathly Hallows	A disease that covers the victim in purple pustules and renders them unable to speak. It may be a type of fungus, as Ron Weasley says that the effect of being unable to speak occurs “once the fungus has spread to your uvula”. The only known cure, according to the portrait of a Healer in St. Mungo's Hospital for Magical Maladies and Injuries, is to bind the liver of a toad around the victim's throat and stand nude in a barrel of eel's eyes under a full moon. The portrait said that he believed Ron had this disease, due to the "unsightly blemishes" on his face. Ron would later use this disease in Harry Potter and the Deathly Hallows as an excuse as to why he was unable to return to Hogwarts, when in actuality he and his friends were out searching for Lord Voldemort's Horcruxes.
Solanum Virus	World War Z/The Zombie Survival Guide by Max Brooks	A virus which has existed since the beginning of human history, which is highly contagious through bodily fluids such as blood. Solanum symptoms include dementia, paralysis in the extremities, and discoloration of the wound, which increase as the virus replicates itself. The virus is centered on the brain, and destroys the cells of the brain and replaces them with the virus. In doing so, the infected victims are declared clinically dead. The virus takes around sixteen hours to replicate, although it varies from individual to individual. Once Solanum has fully replicated, the victim awakes from the coma, with an unquenchable desire for human flesh. The victim also exhibits typical zombie-like behavior such as psychotic behavior and mindless rage, and can only be killed by destruction of the brain.
Stone Sickness	The Edge Chronicles by Paul Stewart and Chris Riddell	Not a human disease, but one which affects humans and other inhabitants of the Edge by attacking the rocks of the flight ships which is the primary means of transport and communication on the Edge. As the flight ships are carried aloft by the rocks, this puts an end to business and trade, resulting in a brief societal collapse followed by a gradual rebuilding of society when the Edge's inhabitants become accustomed to life with Stone-sickness. Symptoms of infected flight rocks include a brief scar, followed by an open wound and a gaping hole as the rock dissolves. Eventually the sky ship drops clean out of the sky. Many theories abound on the origin of Stone-sickness. Some people blame the gods. Others blame the Mother Storm, the mysterious meteorlogical creator of the Edge. Some say that the sky pirate captain Cloud Wolf who perished in the Mother Storm somehow infected her and the Stone-sickness is a result of his pestilence. It is only at the end of the series that it is revealed the Gloamglozer created the disease and it had been incubating inside the Stone Gardens ever since he fled the city of Sanctaphrax almost a century before the sickness.
Stripes	A Bad Case of Stripes by David Shannon	An unnamed disease that causes the affected individual to change color/pattern when names of patterns are used. Apparently it can only be cured and prevented by lima beans.
"T4 Angel Virus"	Hollows (series) by Kim Harrison	The result of genetic engineering, the T4 Angel Virus was spread by infected tomatoes. It wiped out a large percentage of humanity, along with the elves and several other species which had been secretly coexisting. Other species unaffected by the virus, such as witches, vampires, and werewolves, soon equaled humanity's depleted numbers and began living openly. Tomatoes are still feared and shunned by humans throughout the series.
"Teen Plague"	Black Hole by Charles Burns	Also known as the "bug." It is a mutagenic STD which causes grotesque mutations, such as extra body parts, to grow all over the body. Seems to affect only teenagers.
The Pulse	Cell by Stephen King	A powerful virus which lies dormant inside mobile phones and which requires a powerful signal to set off. The exact unleashers are unknown, but are implied to be a terrorist group due to numerous theories in the novel. The virus is implied to have been released just after September 11th, and lain dormant in cell phones ever since. Once the right signal is transmitted and leaked into incoming phone calls, the caller's brain cells immediately disintegrate and they are unable to recognize friend from foe; they are even unable to recognize other people infected with the virus. Inevitably, the infected callers become psychotic and start killing each other, the chaos of which lasts approximately two days before the infected callers have become "stable" enough to cooperate and recognize each other.
V-CIDS	ImmortalsThe Immortals	An AIDS-like virus.
Vampiris	I Am Legend by Richard Matheson	A bacillus (rod-shaped) bacterium that causes photosensitivity, hysterical blindness near mirrors, overdevelopment of canine teeth, and production of a bulletproof adhesive. Victims feed on blood. While in the body, it is anaerobic, and causes the victim to exhibit zombie-like behavior. Outside the body, it sporulates into dust. If an infected person is cut deep enough, the bacteria turns them into powder. Can be treated, but not cured, with a pill containing a fusion inhibitor and dehydrated blood.
Venus Particle	Tyrannosaur Canyon	An extraterrestrial infectious particle found in a lunar rock sample and within a fantastically well-preserved tyrannosaur fossil in the New Mexico desert. It is later revealed that the organism came to Earth via the Chicxulub asteroid which wiped out the dinosaurs. The particle, which was named for its resemblance to the symbol of Venus and femininity, causes rapid mitosis and apparent cellular differentiation in its host.
(unknown)	Please Save My Earth (Boku no Chikyū o Mamotte) by Saki Hiwatari	A mysterious, highly infectious disease that moves quickly through a group and kills its host. The disease's origin, genetic make-up, and its vector are unknown, as is its longevity once outside the host body, but speculation is that it can continue to live on inert/non-biologic surfaces (such as plastic, glass, cement, etc.) in a dormant state long after it has no living host to latch onto. The only known cure for this unnamed disease was developed by the doctor, Shukaido, who succumbed to the disease soon after developing the cure. Tragically, the cure only lasts for approximately seven years before its effects wear off, and the suppressed disease in the victim's system re-emerges at full strength, killing him/her. The last known victim of this plague was Shion.
(unknown)	The Walking Dead	An unnamed disease of unknown origin. When a human is infected by it, the disease will infect all cells, eventually resulting in the clinical death of the host. The symptoms that occur before the victim's clinical death, include fever, headache, fatigue, confusion, hallucinations and paralysis. The disease has a very short incubation period of around 16 hours. After the victim's clinical death, the host will be revitalized and will wake up exhibiting zombie-like behavior. However the disease will only activate lower brain function, mostly those controlled by the brain-stem, where feeding and motor functions are controlled. The host becomes a violent mindless cannibal, and can infect other people by biting. The disease leads to society's collapse and results in a world stricken by a zombie apocalypse.
White Blindness	Blindness by José Saramago	A mysterious epidemic of sudden blindness affecting virtually all humanity, leading to society's collapse. So-called because victims see nothing but a white glare. Not to be confused with the White Blindness in Watership Down which is a name the rabbits use for the real illness Myxomatosis which affects rabbits causing blindness and death.
Wildcard coccus	A Certain Magical Index by Kazuma Kamachi	It is a highly virulent killer bacterium. Its method of infection was very complex and it would mix in with other microorganisms and multiply. It could be transmitted via air, blood, mouth, or skin contact. It could grow even more dangerous by combining with Athlete’s foot, Lactobacillus, or other extremely common pathogens.
Plague of Insomnia	One Hundred Years of Solitude by Gabriel García Márquez	An epidemic brought into the Buendía household and the town of Macondo by Rebeca; the adopted daughter of José Arcadio Buendía and Úrsula Iguarán. This plague, originally coming from the northern Indian kingdoms in La Guajira (Colombia), is identified by the symptoms of wide-open, glowing eyes like those of a cat, and the impossibility of sleeping. Those infected (in the novel consisting of the entire town of Macondo) feel no tiredness or sleepiness whatsoever and hence can work all day and night. However, as time advances, those infected begin to lose all their memories and knowledge of the world; ultimately leaving them in a state in which they have forgotten the names and uses of all things and their own identities. The plague is generally seen as one of the most prominent demonstrations of magical realism in García Márquez's literary works.
White Disease	White Disease by Karel ČapekThe White Disease by Karel Čapek	An incurable mysterious form of leprosy, killing people older than 30.
White Plague	White Plague by Frank HerbertThe White Plague by Frank Herbert	A genetically engineered virus that kills only women. Released only on Irish, English, and Libyan populace.
White Sickness	Burning Bright by Melissa Scott	White-Sickness, a pneumatic histopathy, also known as lung‑rot oruhanjao, translatable as "drown‑yourself" in the language of the story's aliens – is classified as a dangerous condition less because it is fatal, which it is, than because it is contagious until treated. Simple organ transplants inevitably fail, due to the mechanisms by which the disease alters the lung tissue, slowly dissolving it into a thick white mucus, so that the patient drowns in body fluids even as the lungs themselves stop working.
Xenovirus Takis-A	Wild Cards by George R. R. MartinWild Cards by George R. R. Martin	Xenovirus Takis-A, also known as the wild card virus, works by completely altering the victim's DNA. It's been theorized that the process is guided by the victim's own subconscious, influenced by the person's desires or fears. In this way, the virus works as a modern Aladdin's Lamp. The transformation is extremely individual, no two persons are affected in exactly the same way. In 90% of cases, the victim's body can't assimilate the extreme changes, and the person dies horribly. These cases are called black queens. From the survivors, 9 out of 10 are changed for the worse, becoming monstrous creatures nicknamed jokers. The miraculous 1% of infected are changed for the better and become aces, gifted with superhuman physical or mental capabilities while still remaining human in appearance.
Xenovirus Takis-B	Wild Cards by George R. R. MartinWild Cards by George R. R. Martin	Xenovirus Takis-B, also known as the trump virus, is an artificial organism created by Dr. Tachyon as a possible cure for the wild card virus. Ideally, the trump virus reverses the genetic changes caused by the wild card virus, transforming a wild carder back into a normal person. The trump virus is only successful in about twenty-four percent of attempts. Forty-seven percent of the time it doesn’t work at all, and an appalling twenty-nine percent of the time, it outright kills the patient. In other words, it’s more likely to kill than cure. The Jokertown Clinic only uses the trump virus as a last resort, in the most severe cases where the victim has nothing to lose.

In film

Name	Source	Symptoms
Brain Cloud	Joe Versus the Volcano	The brain cloud has no symptoms—apart from quickly and painlessly killing in about six months.
ComaThe Coma	PlagueClive Barker's The Plague	Affects all children. Induces a 10-year coma, after which the children simultaneously wake up and desire to kill all adults.
Carnosaur virus	Carnosaur	A genetically engineered virus created by Dr. Jane Tiptree. Infects fertile women of child-bearing age (including Dr. Tiptree herself), making them pregnant with a dinosaur. Rather than being born, upon maturation the dinosaurs tear their way out of the womb, killing the woman in the process.
Fever"The Fever"	Cabin Fever Cabin fever 2:Spring fever	Necrotizing fasciitis which causes massive hemorrhaging and tissue necrosis. The first symptom of the disease is usually a painful rash, which develops into a scabby or weeping wound. In later stages, tissues become soft and slough away. The initial rash stage can be exacerbated by harsh physical trauma, as was seen when one afflicted woman discovered hand-shaped rashes on her body, where she had recently been tightly held during a passionate sexual encounter. It also seemed to indicate that physical exertion also accelerates the progression of the disease. The disease is transmitted when an infected creatures' blood is exposed to a victim's bloodstream (bare skin contact with infectious blood is implied to not result in infection). It can also be contracted through unprotected sexual activity and by drinking contaminated water. The disease spreads cross-species and was initially discovered in a dead dog. Where the dog contracted the disease is unknown. Despite the name of the franchise, fever is never indicated as being a symptom of the disease.
Geostigma	Final Fantasy VII: Advent Children	A disease caused by Jenova's presence in the Lifestream as it rose to destroy Meteor in the ending of Final Fantasy VII. Decreases the efficiency of the body's immune system-like inner Lifestream current. Also causes exhaustion and black sores appearing on the skin. Mostly affects children due to their weaker constitutions. Healed by Aerith Gainsborough's Great Gospel healing rain. "The Stigma. It's a symptom of alien matter infesting the body. The body tries to eliminate it, and overcompensates. Inside our bodies is a current like the Lifestream. That current is what fights off any malevolent intruders." - Vincent Valentine
Hemoglophagia (HGV)	Ultraviolet	Disease responsible for turning many humans into vampire-like creatures. Contrary to most vampiral diseases, hemoglophagia drastically shortens the lifespan of an infected individual to little over a decade.
The Host's Disease	The Host	The unnamed disease carried by the giant monster terrorizing South Korea. In actuality, there was no virus; the government claimed the monster was spreading a disease just to save face.
Herpes Simplex 10	Beverly Hills Cop	A type of venereal disease where a person's body parts can fall off.
Infertility epidemic	Children of Men	A mysterious epidemic has led to worldwide infertility in women. The human race has lost the ability to reproduce.
Krippin Virus (KV)	I Am Legend	A genetically re-engineered measles virus originally created as a "miracle cure" for cancer, but mutated into a lethal, highly pathogenic strain. KV has a 90% mortality rate; less than 1% of humans are immune. Two transmission vectors for the pathogen are inhalation and infected blood, with two corresponding immunity profiles. Infected humans who did not die began exhibiting early symptoms of rabies and degenerated into a state driven by rage. A major symptom is that the adrenal glands are "permanently open", giving victims increased strength, speed and agility but also a faster metabolism. This results in increased body temperature, heart rate, and breathing speed, making those infected hyperventilate constantly. Pupils became permanently dilated and skin became hypersensitive to UV radiation, forcing infected hosts into a nocturnal life cycle. Loss of body hair is another symptom. Non-humans such as rats and dogs are also susceptible to KV. They are sensitive to blood. These infected are similar to vampires.
Lampington's Disease	Last Holiday	In the original 1950 film, the disease seems to have been a tumor in the abdomen (the patient's x-ray is used to indicate something "between the stomach and the small intestine," although a shot of the pelvis is actually being shown). Here, it is an untreatable, terminal condition which is nearly pain-free, but which leads to coma and death within a couple of weeks to a couple of months at the most. It is explained as a recently discovered condition, described by and named for Sir Trevor Lampington, a character who also appears in the plot. In the 2006 remake, the disease has morphed into a neurological disease causing multiple brain tumors, rapidly progressing to death within a few weeks if not treated with an exorbitantly expensive operation.
MacGregor's Sydrome	Batman & Robin	A four-stage disease that Mr. Freeze's wife, Nora, was suffering from and was placed in cryogenic stasis for. The film also revealed that Batman's butler, Alfred Pennyworth, was also suffering from Stage-1 MacGregor's. Mr. Freeze successfully created the antidote for Stage-1 of the disease, and gave some of it to Batman as an apology for thinking that Batman killed Nora (which was actually a lie fabricated by Poison Ivy).
Mad Zombie Disease	Zombieland (film)	The disease which caused people, upon receiving a bite from one of the infected, to become zombies. The disease is a mutation of Mad Cow Disease, which became Mad Human Disease, and then mutated to form Mad Zombie Disease.
Malignalitaloptereosis	The Sword in the Stone	A rare disease which causes the victim to break out in spots, followed by hot and cold flashes, then violent sneezing. During the wizard's duel, Merlin had transformed himself into the germ that caused this disease and infected Madam Mim with it.
Meningoencephalitis Virus One	Contagion	A highly contagious and lethal meningoencephalitic virus. A paramyxovirus that infects both the lungs and the brain, causing hacking coughs and fever and a severe headache, followed by a seizure, brain hemorrhage and ultimately death.
Methuselah Syndrome	Blade Runner	A genetic disease resembling progeria that causes faster aging
Motaba	Outbreak	A deadly, virulent Ebola-like virus from the jungles of Zaire, Than which later infected a fictional Californian town within few days.
Patriot	The Patriot (1998)	A unnamed highly contagious airborne virus which has been stolen from a government biological warfare laboratory.

Carriers are immune to Cuvier Syndrome can transform into a demonic reflection of their inner personalities, referred to as Atma. However, everyone with the virus feels an insatiable hunger for the flesh of other carriers. If this hunger is resisted for too long, the carrier will eventually enter an irreversible state of mindless bloodlust, losing the ability to return to human form.
Asmodeus	Terranigma	Many ages before Ark's adventure to the surface of the world, the previous generations of Humanity were decimated by an airborne virus with an estimated mortality rate of 90%. The virus was named by Dr. Beruga who was able to synthesize a vaccine of 80% effectiveness for it. Asmodeus was later utilized as a bio-weapon to completely depopulate a city, save for one child survivor who was seemingly unaffected and hid underground.
Blacklight Virus	Prototype	The Blacklight virus "plugs in" and activates the junk DNA in a target, causing biological changes that create (and recreate) a sentient mind inside the infected creature. It acts by affecting the protein encoding regions of the promoter introns in each cell. As a retrovirus, it contains both RNA and the reverse transcriptase enzyme, allowing it to insert its own genetic codes into living cells. It enters, re-purposes and changes the cell, replicating previously dormant non-coding segments of DNA. More often than not, these changes are too drastic and 99.99% of subjects die from massive organ failure and cell saturation however some variants have yielded other beneficial results; endowing the infected organisms with incredible superhuman genetic prowess, that greatly increase their natural abilities to levels far exceeding human capability.
Blight Disease	Dragon Age	The Blight disease is a kind of corruption spread by the evil Darkspawn. The disease corrupts all living organisms which either go mad, develop physical afflictions, and/or perish outright.The longer an infected creature 'lives', the more it will manifest hair loss, aggressive or even rabid behavior and numerous deformities, protrusions, boils and sores.
Chimeran Virus	Resistance: Fall of Man	It mutates human DNA the infected into chimeran DNA thus make them as the enemies of the series.
Chronic Angelus Crystallus Inofficium	Tales of Symphonia	A progressive disease caused by a Cruxis Crystal mounted upon a Key Crest. The wearer's body gradually crystallizes, starting with the skin, into the same substance that forms Exspheres. When the crystallization reaches the internal organs, the sufferer perishes.
Corprus	The Elder Scrolls III: Morrowind	Corprus causes incredible mutations in humanoids, but it is an almost non-communicable disease. People infected with blight are often sent to a special institution called the Corprusarium, which was made for researching corprus. Corprus is caused by the volcanic ash that emanates from Red Mountain, but, as a positive side effect, grants 100% disease immunity. The only known antidote is proven to destroy corprus, but ends up killing the victim as well. However, the player is able to take the antidote without any adverse effects, presumably because he is the reincarnation of the demi-god Nerevar.
Corrupted Blood	World of Warcraft	Initially contracted from fighting Hakkar, the God of Blood, in the dungeon of Zul'Gurub. Highly infectious, with an incubation period of 2 seconds and can infect any person in the immediate area. Referred to players as "the Plague", "Hakkar's SARS" or "WoW AIDS" for a major outbreak of the virtual plague in the game due to a design oversight.
Creeping Derangea	Advance Wars: Days of Ruin	An artificial virus that is revealed to be a failed Bio-Weapon created by Dr. Caulder to test the extent of IDS technology. Due to its inherent flaw of photophobia, creeping derangea is only able to thrive when the sun was effectively blocked out by the vast amounts of dust that were kicked up into the troposphere and stratosphere by the apocalyptic meteor impact events. The Virus is initially only able to infect those under the age of 20 but a new strain is somehow introduced that can infect older hosts over time. Symptoms include headaches, paranoia, and a black diamond on the skin called "the mark". It causes flowers to grow inside a person and break out of the skin. A beautiful, albeit excruciatingly painful, way to die. Its scientific name is Endoflorescens terribilis. It is also known as The Creeper and the Green Thumb.
C-Virus	Resident Evil 6	A new, further evolved version of the T-Virus. Developed by Neo-Umbrella, it is responsible for creating the highly evolved, more intelligent J'avo, as well as being used in the worldwide bio-terrorist attacks. Jake Muller, being descended from Albert Wesker, is resistant to the disease. Because of this, Jake is seemingly being hunted by Ada Wong and her agents.
Cuvier Syndrome	Digital Devil Saga 2	Caused by exposure to corrupted sunlight, this noncommunicable disease petrifies the bodies of its victims, literally turning them to stone. The rate of petrification seems based on the level of sunlight exposure: one victim in full sunlight attempted suicide, but was unable to pull the trigger before being petrified. Carriers of the Atma Virus are immune.
Diathronitis	Larn	Afflicts daughter of player character; serves as primary motivation for gameplay.
Doll Syndrome	hack GU.hack//G.U.	A mysterious medical condition in which a person falls into a completely unresponsive state. Doll Syndrome is in fact a physical side effect to an infection by AIDA. Salvador Aihara tries to do an undercover investigation regarding Doll Syndrome in especially young children for his show "Online Jack".
Shiva I-VII	Fallen Earth	The SHIVA virus, or at least SHIVA I, is hinted to be an airborne virus with a quick infection exposure time, and therefore has qualities much like a modern chemical weapon. Overall the SHIVA virus appears as seven distinct forms, with naming conventions of SHIVA I through SHIVA VII, with the seventh version being mostly non-lethal. The virus is named after te Shiva, the Hindu God of death due to the dance-like convulsions that it causes its victims
Flood Parasite	Halo	The Flood Parasite is depicted in the Halo franchise as a Parasite that mutates infected hosts into creatures similar to zombies. Depending on the size or condition of the Host's body, the Parasite either uses the host as-is to pursue new victims, or breaks it down to create "pure forms" from its biomass.
Forced Evolutionary Virus	Fallout	Originally known as the Pan-Immunity Viron Project, FEV, along with radiation, is responsible for many mutations in the wastelands. The most visible of these are the super mutants, former humans granted incredible strength and endurance as result of being infected. Exposure to the virus is also known to be fatal in many cases. FEV serves as a major plot element in Fallout, Fallout 2 and Fallout 3.
FoxDie	Metal Gear Solid	FoxDie is a virus responsible for killing people with certain genetic markers via cardiac arrest. FoxDie is given to protagonist Solid Snake by Dr. Naomi Hunter, only it is engineered to go off at an indeterminate time. FoxDie was also the cause of death of Liquid Snake, Decoy Octopus (impersonating DARPA chief Donald Anderson), and the ArmsTech President.
G-Virus	Resident Evil 2	A mutagenic pathogen which causes the host to become a big, constantly evolving, practically unstoppable killing machine, with exceedingly high attack power and immense vitality, in addition to the ability to regenerate and mutate so quickly the carrier virtually loses its mortality. The purified virus can be injected directly into the host, or a mutated host can implant a small larvae, called a G-embryo into another host. The latter mode of transmission is most successful when the host and the new victim are genetically similar. The virus would later be merged with the T-Virus by Umbrella scientists in an attempt to balance the G-virus' rapid evolution with the T-virus' stability, creating an extremely dangerous, electromagnetic-capable variant called the T/G Virus.
Gagne	Michigan: Report from Hell	An experimental bioweapon that was developed in a consortium by the ZaKa Conglomerate, the U.S. Government, and the U.S. Military. It is a mutagenic virus that can be transmitted in the air and by contact with body fluids. Gagne takes the form of a thick fog that has covered the entirety of Chicago, Illinois and is causing animals and people to horrifically transform into grotesque monsters with large maws that can spawn leech-like larvae. Stage 1: No discernible changes in physical appearance and body temperature. Actions become sluggish. Stage 2: Subject begins to spawn leech-like larvae which are violently spewed from the mouth. Stage 3: Subject undergoes horrific transformation and becomes aggressive and sensitive to nearby sounds.
Gangliated Utrophin Immuno Latency Toxin (GUILT)	Trauma Center: Under the Knife	A series of eight parasitic pathogens created by the medical-terrorist group Delphi. Despite its ingame introduction as a toxin, GUILT is referred as a "moving tumor", but behaves more like a parasite. During ingame sequences where the player operates on patients, GUILT diseases are normally shown as a pseudo-sentient core that attacks the patient from within, using lacerations, tumors and other ailments. Individual strains are named after Greek days of the week (Kyriaki, Deftera, Triti, Tetarti, Pempti, Paraskevi, Savato), the only exception being the eighth strain, called "Bliss". Neo-GUILT strains, which were developed independently from the original GUILT project, introduce four more strains (Nous, Bythos, Sige, Aletheia). Some GUILT survivors were also inflicted with a variation of the disease, dubbed the PGS (Post-GUILT syndrome).
Genophage	Mass Effect	Genophage is a biological weapon deployed against the krogan species designed to severely reduce population numbers by infecting the species with genetic mutations. The plague causes most krogan pregnancies to end in stillbirth, with most fetuses never even reaching that stage of development.
Gray Death	Deus Ex	A global plague engineered using nanotechnology within a Universal Constructor by Majestic-12, the Gray Death virus is actually a hybrid (cyborganic) disease of biological and mechanical structures. It is based on the adverse and ultimately lethal effects of nanotechnology on an unmodified human body. Named the Gray Death because of the gray patches of discolored scar tissue that cover its victims' skins, if and when the disease is cured. Symptoms include the aforementioned discoloration of the skin, coughing, physical pain and death.
Hyper-evolutionary virus	StarCraft	The Hyper-evolutionary virus is a retrovirus produced by Zerg Queens. It is used to mutate "lesser" creatures into zerg warrior breeds. Only a small percent of humanity is fully compatible, who retain personality, intelligence, and psionics. Others mutate into living bombs, utterly dominated by the Overmind. It has a re-animation side-effect. It is transmissible through fluid transfer only, much like Solanum.
Incuritis	Apollo Justice: Ace Attorney	A rare, but lethal disease, curable only through the use of a medicine made from the Borginian Cocoon. The cure is very difficult to make, and if made incorrectly, it is a deadly poison, and thus the exportation of such a cocoon is illegal. The Chief Justice's son is afflicted with the disease.
Kepral's Syndrome	Mass Effect 2	Drell are an almost extinct race, as their arid home planet Rakhana underwent an ecological disaster due to overpopulation. 350.000 of them were relocated to the humid, ocean-covered planet of Kajhe; this change of habitat and the unwillingness of the drell to separate themselves from the indigenous population, the jellyfish-like hanar, results in some of them developing this disease, which primarily damages their blood's ability to transfer oxygen. It is noncommunicable, and there is currently no known cure, though leading hanar scientific authorities are working on creating a genetic adaptation.
Las Plagas	Resident Evil 4	A parasitic, organism which can infect a variety of hosts, including humans. It has the ability to control its host's behavior, inducing a hive-like mentality among the infected and extreme hostility towards uninfected individuals. The infected retain most of the characteristics of humans such as fine motor skills as seen through their use of simple weapons such as scythes and axes, and more complicated weapons such as chainsaws and chainguns. They are seen to obey "Queen" parasites, much like ants.
M2448 virus (The Freak Virus)	Crackdown 2	The virus called M2448 was created by Catalina Thorne, the leader of Cell, during her time as a medical student working for the Agency. She conducted secret experiments of the virus but was discovered by the Agency and was kicked off the Agency-sponsored medical programme. She was enraged by this and wanted revenge on the Agency because it apparently ruined her life. To get her revenge she offered free vaccinations to the people of Unity Heights (formerly "The Corridor"), she was actually vaccinating her victims with the M2448 Virus which tuned them into Freaks. The virus spread across Unity Heights very quickly and soon made its way into the two other boroughs of Pacific City.
Marker: DNA sequence	Dead Space	After the human colony, on planet Aegis discover an alien Marker, that contained complex and powerful DNA sequence, that enabled dead cells to revive. Unfortunately, one of the scientists working on this DNA sequence, dropped the dish containing these engineered cells. The cells, eventually infected one scientists, which then lead to altered mutations of the human body.
Maverick Virus	Mega Man X	A virus that affects Reploids. Causes violent insanity and is passed by touch. Victims can sometimes retain their intellect. Combination with the intelligence of the Maverick Hunter Sigma created a variant form called the Sigma Virus, which is airborne. Mega Man X can be harmed, but not mentally suborned, by this virus. Zero is actually strengthened by exposure, due to his unique status. The Zero Virus is a further evolved, faster version.
NE-Alpha Parasite	Resident Evil 3	The NE-Alpha, or Nemesis Alpha, Parasite has an immunity to the T-virus, and is used to protect the higher brain functions of B.O.W.'s. However, if the B.O.W. is incompatible with the parasite, they die inside of twenty minutes. If they are compatible, however, the parasite acts as a second brain, taking over the functions mof the T-virus ravaged host brain. The host increases in size and strength; and become hardy enough to survive multiple gunshot wounds.
NE-Beta Parasite	Resident Evil: Operation Raccoon City	The NE-Beta (Nemesis Beta) parasite is an evolved form of the NE-Alpha parasite. the parasite is capable of bonding to all B.O.W.s, from zombies to T-103 super soldiers. the parasite has an insectoid appearance, as opposed to the octopous-like form of its predecessor. However, it is prone to decapitating its host.
Neuro-Immuno Deficiency Syndrome (N.I.D.S.)	Sonic The Hedgehog (series)Sonic The Hedgehog	A rare, incurable, and fatal disease. Shortly after Prof. Gerald Robotnik refused G.U.N.'s request for him to discover the secret to immortality, his granddaughter Maria contracted N.I.D.S., causing Gerald to reconsider and begin Project Shadow. The cure was never found, despite Gerald's success at creating the ultimate life form. Maria later died of a gunshot wound during G.U.N.'s extermination of all involved in the project.
Porphyric Hemophilia	Elder Scrolls III: Morrowind, Elder Scrolls IV: OblivionThe Elder Scrolls IV: Oblivion	Causes vampirism after an incubation period of three days. If the player is infected, they can go through a quest to cure the disease, however it is not necessary to be cured to complete the quest.
Pox of LeChuck	Tales of Monkey Island	The Pox of LeChuck (also named LeChucken Pox in the final episode) is a plague apparent in Tales of Monkey Island that swept across the Caribbean when Guybrush stabbed LeChuck with an enchanted voodoo sword at the Rock of Gelato. This caused LeChuck to be stripped of his voodoo powers, releasing a pandemic that transformed many pirates into green-skinned, foul-mouthed monsters. It also spread to Guybrush's hand, giving it a life of its own (even after being cut off by Morgan LeFlay), as well as infecting his wife, Elaine Marley. The only known cure is La Esponja Grande, which Guybrush embarks on a quest to find after speaking with the Voodoo Lady.
Progenitor Virus	Resident Evil	In the back-story of the series, the Progenitor virus is the primary virus created by the Umbrella Corporation, a mutagen based on ebola, with some of its components extracted from strange flowers that bloom underground, seen in Resident Evil 5. Successor viruses include the T-Virus, the G-Virus, and T-Veronica Virus.
Phazon Madness	Metroid Prime	A virus transmitted by being in close proximity to Phazon. The victim's mind is warped so they can no longer tell friend from foe, and exist only to destroy. Phazon Madness is extremely contagious, and it later develops into Phazon Fever, wherein the victim gains an obsessive compulsive disorder regarding Phazon. Infected victims can utilize Phazon as a weapon and normally can only be killed by Phazon itself.
Pokérus	Pokémon	A virus that afflicts Pokémon. Though it is incurable, it has no negative effects, and is in fact helpful. Pokémon afflicted gain double effort values in battle. The Pokémon retains this ability even after its contagious period of 48 hours has passed. Transmission is by proximity in a party, and the 48 hour "clock" is stopped by placing the Pokémon into a PC.
Radical-6	Zero Escape: Virtue's Last Reward	Radical-6 was a virus developed by the apocalyptic cult "Free the Soul" to destroy human civilization. A highly infectious virus, it causes the human brain to experience time at a 40% slower rate, and eventually drives its victims to suicide. The global pandemic eventually leads to a desperate (and hinted to be Radical-6 induced) plan to detonate 18 anti-matter generators simultaneously, initiating a nuclear winter.
Roboenza	Mega Man 10	A virus that affects humanoid robots, causing flu-like symptoms and eventually homicidal tendencies. Created and subsequently cured by Dr. Wily. Some theories hold that it is related to the Evil Energy from Mega Man 8 and the Maverick Virus from the Mega Man X series
Rotten World Gas	Lollipop Chainsaw	A poisonous gas from the Rotten World (Hell) which leaks through interdimensional cracks caused by the Necromancer Swan when he cracks open a gate between Earth and Rotten World. This gas leaks through the cracks and kills everybody who inhales it within minutes, shortly reanimating them as psychotic zombies within a short while. It appears the gas is transmittable through bites, and therefore contagious. In hallucinations, the gas is also shown to affect animals.
Rust Lung/Lambency	Gears of War 2	When the Lightmass bomb that killed the multitude of Locust monsters in the first game vaporized the liquid element "Imulsion", the gas seeped into the atmosphere of planet Sera, resulting in 'Rust Lung', a disease that spreads quickly and deadly. However, in Gears of War 3 it is concluded that Imulsion is not just a fuel, it's a parasite, and it began to spread to humans as it had to Locust. In fact, as the subterran Locust tried to escape being turned into infested "Lambent", they had to start the genocide of the surface-occupying humans. The Lambent organism is present to some degree in every human's cells by the events of the game, and 'rust lung' is a sing of approaching transformation into a "former human", or just Former, a zombie-like creature. Locust, however, appear not to lose sentience after transformation, and some of them develop uncanny mutations amidst the heat of battle. All Lambent inherit Imuslion's qualities: glow in the dark and explosive properties. The point of the third game is to deal with the Imulsion's assault on the surface of the planet.
Scurge	Scurge: Hive	A parasite that can infect biological, technological, or coherent energy systems. It takes about one minute to overwhelm the special filters designed to ward off its infection.
"Green Flu" (Previously Unknown)	Left 4 Dead, Payday The Heist: No Mercy	The Green Flu, commonly referred to simply as The Infection, has caused most humans who come in contact with it to change into homicidal, zombie-like beings. Anyone can catch it, but there are few out there who show no symptoms of the virus. They can, however, spread it to whoever comes in contact with them. These carriers seldom realize they are spreading the virus, leaving a path of destruction in their wake.
The Plague	Mass Effect 2	The Plague is a virus possibly created by the Collectors which infects all species except humans and vorcha, with the latter being resistant to any infection, and the former being immediately blamed for the spread of the plague and hunted down by local non-human criminals. It causes horrible sores, a bad cough and coughing up blood, as a result of rapid mutations to the respiratory systems. It was being spread through the ventilation system of the slums of Omega by the vorcha under orders of the Collectors but was stopped by Shepard and doctor Mordin Solus, since Omega has no authorities whatsoever and the affected area was simply sealed until everyone would die.
The Plague of Undeath	Warcraft III	The Plague is responsible for the entire Undead race. It can re-animate dead creatures with a reasonable degree of sentience. However, the creature is usually dominated by the undead command structure, but they can escape from the tyranny of undeath. It also causes the soil beneath and around Undead structures to change into a substance known as Blight, which is poisonus to most plants.
The Rat Plague	Dishonored	The Rat Plague killed almost half of the population of the city of Dunwall, the fictional city from the game Dishonored. Victims of the rat plague can cure themselves via use of Sokolov's Health Elixir. Once blood comes from the Nose or Eyes there is no way to be cured. It is also known as the doom of Pandyssia.
Rosalia Virus	Trauma Team	A variation of viral hemorrhagic fever, capable of killing patients in days. The virus was originally found in the blood of Rosalia Rosselini by Cumberland College professor Albert Sartre. Sartre and his son attempted to use the virus to cure all disease, but instead found that it could not be used for positive means. An outbreak of the virus occurred, resulting in the Cumberland College Incident, where Sartre and Rosalia escaped to Mexico, and his son lost all memory of the incident, but was arrested and sentenced to 250 years of imprisonment under the ID "CR-S01". However, Sartre was inflicted with the virus, causing him to fall to insanity, killing Rosalia. Rosalia's blood splattered onto nearby flowers, which monarch butterflies fed upon, acting as vectors that caused a second outbreak. A variation of the Rosalia virus was encountered once, when one of the Rosalia patients, Naomi Kimishima, also had a pre-existing incurable genetic disease (thought to be related to GUILT). Interactions between the genetic disease and Rosalia gave birth to a "Twisted Rosalia" strain, which only one case was known to be documented.
Stigma	Trauma Center: New Blood	A virus accidentally created by Markus Vaughn and Lloyd Wilkens. It later is used as a bioterror weapon by the group Parnassus. It comes in six strains, named after body parts it resmbles or attacks (Cheir, Soma, Ops, Onyx, Brachion, Cardia). Unlike other pathogens, which store their genetic information in DNA, Stigma stores its genetic information in a film-like structure making it unique among pathogens.
T-Abyss Virus	Resident Evil: Revelations	A variant of the T-Virus, designed by FBC CEO Morgan Lansdale to show the world the dangers of bio-weapons and increase his own personal power through use of the 'Veltro' terrorist group. The virus crates zombies and BOWs who are strongly linked with water, and have numerous aquatic features such as tentacles and crab-like shells. It is encountered in the game when 'Veltro' threaten to infect the world's oceans, hoping to exact revenge for the loss of much of their forces during the bio-terrorist attack on the floating techno-utopia Terragrigia. It is encountered during exploration of three research vessals, where it has transformed the crew and several sea creatures into zombies, mutants and Tyrants.
T-Veronica Virus	Resident Evil Code: Veronica	A powerful strain of the Progenitor Virus, created by combining it with a rare retrovirus found in the genetic make-up of ant queens, discovered by unstable scientific genius Alexia Ashford, the result of an advanced cloning experiment. It is encountered in Code: Veronica, when it is being used by Alexia Ashford in her attempt to take control of the world. She experiments on her father, then on herself; her father is transformed into a terrifying monster, while she, going into hibernation after giving herself a dose of the Virus, manages to gain control over it and retain her personality and intelligence. She eventually becomes a dragonfly-like creature who has to be killed by Chris Redfield. It appears again in the 'Operation Javier' section of Darkside Chronicles, where it is being used by Javier Hidalgo to cure his daughter Manuela of an inherited illness. He also tried to cure his wife, but the virus overwhelmed her and turned her into a mutant. Manuela uses her developing powers (similar to Alexia Ashford's abilities before transforming into her insect form) to defeat the mutated Javier, and is then evacuated by Leon Kennedy and Jack Krauser. If Manuela survives at the end of the game, it is said that she is cared for by the US government, but her ultimate fate is left unknown.
T-Virus	Resident Evil	(short for Tyrant Virus, after the humanoid BOWs it is used to create) A virus that causes dementia and cellular necrosis in humans, turning them into zombie-like creatures who are difficult to kill. It can easily mutate into other strains, some of which have mutagenic effects on the host. In insects or amphibians, the resulting mutation often involves increased aggressiveness, increased size, and (almost always) the development of poisonous traits. In mammals, the results include aggressiveness, physiological changes of varying degrees, and an extremely increased evolutionary rate. However, it is shown that some humans can bond with the T-Virus and its variants and gain heightened speed, strength and strange powers while retaining their personalities, as in the case of Albert Wesker and Alexia Ashford. Variants include the NE-T virus, T-G Virus, the T-JCCC203 (used for pharmaceutical, but killed two people) and many others.
Technocyte Virus	Dark Sector	The metabolism of victims are increased and the surface of their skin hardens and forms a metallic exterior. The infection continues to mutate the host, driving them insane from the intense pain. The infected then become wildly aggressive and unpredictable, attacking anyone that is not infected on sight. The disease can be spread by physical contact and can affect animals as well as humans.
Tiberium poisoning	Command & Conquer	Tiberium crystals start to grow on a person's skin. These skin crystals eventually force their way through the persons vital organs, killing them. If the infestation is in a certain proportion, the victim mutates into a living bag of rotten skin and organs, called a visceroid.
Uroboros	Resident Evil 5	An advanced strain of the Progenitor virus, the Uroboros virus was created by Albert Wesker, with inadvertent help from Jill Valentine. Exposure to Uroboros can lead to one of two things – forced evolution via DNA integration, leading to extremely heightened abilities, or rejection via the virus, leading to the parasitic nature taking over and forming a mass of black, leech-like pustules, which can grow in size if exposed to more organic matters. The only individual known to survive the process was Albert Wesker, which was more than likely due to the fact of his previous exposure to the T-virus. Other beings that took positive mutations from the Uroboros virus include the Reapers; cockroaches exposed accidentally to the virus, who then in turn grew largely in size, gained armour-like carapaces and scythe-like appendages, explaining the name.
Wailing Death	Neverwinter Nights	A bubonic-like plague that infects almost the entire city of Neverwinter. Thought to be just a natural plague, it is later discovered that it was magically created and unleashed upon the city.
(Unknown)	Madworld	A disease created by the Organizers to force innocent people to compete in the bloodsport Deathwatch for an antidote.
Van Horton's Syndrome	Saturday Night Live	In the October 4, 2005 episode, Van Horton's Syndrome is a fictional condition also called Voice Imodulation or VI. This is a disease in which the people affected cannot control the pitch or volume of their voice. This disease also effects many Americans, including the guy who plays Rodge on what's happening and tennis great Pete Sampras. Although Pete Sampras suffers from low-grade voice imodulation and is a poster child for VI awareness
X-2 Virus	BattleTanx, BattleTanx: Global Assault	An extremely deadly virus released in 2001 and further researched in 2006 that killed 99.9% of the world's human female population that did not possess a special psychic ability known as 'The Edge'. Those that were spared were treated with the utmost respect, authority, and loyalty, thereby earning their title of 'Queenlord'.
Yellow Death	1213	A deadly virus which contaminated the entire planet Earth and certain parts of the Tessa Life Orbital. Humans are killed in short time upon infection, but cloned humans are transformed into killer zombies. When 0916 got a large dosage of the virus he mutated into a yellow, four-armed monster with two retractable spines and tentacles. 1213 however was unaffected by the virus due to a successful Immunization to the virus.
Twin Fever	Metroid Prime	A Virus native to Twin Tabula causing double vision. When the twin sight fades, the victim is near death.
Kuru (Zombie version)	Dead Island, Dead Island Riptide	Is a neurological disease endemic to the Papua New Guinea region. It is widely passed among the local tribes and is believed to be the cause of the zombie outbreak. Doctor West needs a non-mutated strain of this disease to work on a cure. Doctor West also believes that people with O Negative blood are unsusceptible to the infection
