|Transmission electron micrograph of Human orthopneumovirus|
The genus Orthopneumovirus consists of pathogens that target the upper respiratory tract within their specific hosts. Every orthopneumovirus is characterized as host specific, and has a range of diseases involved with respiratory illness. Orthopneumoviruses can cause diseases that range from a less-severe upper-respiratory illness to severe bronchiolitis or pneumonia. Orthopneumoviruses are found among sheep, cows, and most importantly humans. In humans, the orthopneumovirus that specifically impacts infants and small children is known as human respiratory syncytial virus. Pneumoviruses have been traced by researchers from the Center for Disease Control and Prevention and the University Medica Centre in Utrecht, Netherlands on how orthopneumoviruses attack infants and small children.
|Orthopneumovirus||Bovine orthopneumovirus||bovine respiratory syncytial virus (BRSV)|
|Human orthopneumovirus*||human respiratory syncytial virus A2 (HRSV-A2)|
|human respiratory syncytial virus B1 (HRSV-B1)|
|Murine orthopneumovirus||murine pneumonia virus (MPV)|
Table legend: "*" denotes type species.
The genus Orthopneumovirus is included in the family Pneumoviridae. Orthopneumoviruses are found specifically in the members of the species Homo sapiens, Ovis aries, Capra aegagrus hircus, Bos primigenius, and the order Rodentia.
The most common pneumoviruses are as follows:
•Bos primigenius: bovine respiratory syncytial virus
•Rodentia = murine pneumonia virus
Having a weak immune system and pre-existing conditions such as asthma can be leading factors in catching an orthopneumovirus. In elderly adults, having chronic heart or lung disease is also risk factor. Being in close proximity to a host who has been infected with an orthopneumovirus can also be a risk since most transmission happens via respiratory.
Transmission of an infectious agent by another person or animal can be through blood, needles, blood transfusion, a mother to fetus, coughing, sneezing, saliva, or air transmission. Healthcare providers will determine the severity of the virus and possible treatment options. Healthcare providers will also decide if hospitalization is needed for more intense cases.
Treatment plans are not specific and are based upon a specific host's current symptoms. Antibiotics and isolation are the first course of action for the infected host. In more serious cases, supplemental oxygen may be used to aid in oxygen intake. In severe viral detection, intubation and the use of a mechanical ventilation will be inserted as a breathing apparatus.
The best methods of prevention of orthopneumovirus infection are covering cough and sneezing to prevent transmission of possible pathogens. Isolating animals and humans that have a pneumovirus is the best way to prevent the virus from spreading. Molecular studies have been on the rise due to continuing materials and information obtained regarding recombinant DNA arrangements that might offer a foundation for vaccine development. Currently animals are able to receive vaccines specific to their virus strand. During cold and peak flu season, infants and small children have the option to receive monthly injections of small medication doses at a weak strength to help prevent virus/ host attachment.
Human respiratory syncytial virus (HRSV) is the most known orthopneumovirus because of its direct correlation and importance in humans. RSV is the leading viral agent among pneumoviruses in pediatric upper respiratory diseases globally. New pneumoviruses have been discovered in the Netherlands among 28 children according to studies. Certain studies have isolated the children in hospitals to identify specific causes, contagion levels, and treatment options among those children.
