|Look up nCoV or novel coronavirus in Wiktionary, the free dictionary.|
A novel coronavirus (nCoV) is any recently discovered coronavirus of medical significance not yet permanently named. Although coronaviruses are endemic in humans and infections are normally mild (such as the common cold, which is caused by human coronaviruses in about 15% of cases), cross-species transmission has produced some unusually virulent strains which can cause viral pneumonia and in serious cases even acute respiratory distress syndrome.
The following viruses could initially be referred to as "novel coronavirus", often with retroactive addition of the year of discovery, before being given a permanent designation:
|Initial name||Officially named||Informal names||Original host[a]||Place of discovery||Disease caused|
|2019-nCoV||Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)[b]||SARS virus 2||bats||Wuhan, China||coronavirus disease 2019 (COVID-19)[c]|
|2012-nCoV||Middle East respiratory syndrome-related coronavirus (MERS-CoV)[d]||Middle East virus, MERS virus, camel flu virus||camels, bats||Jeddah, Saudi Arabia||Middle East respiratory syndrome (MERS)|
|2005-nCoV||Human coronavirus HKU1 (HCoV-HKU1)||New Haven virus||mice||Hong Kong, China||unnamed, extremely rare, usually mild variant of coronavirus respiratory syndrome|
|2002-nCoV||Severe acute respiratory syndrome coronavirus (SARS-CoV)[b]||SARS virus||civets, bats||Foshan, China||severe acute respiratory syndrome (SARS)|
All four viruses are part of the Betacoronavirus genus within the coronavirus family.
The word "novel" indicates a "new pathogen of a previously known type" (i.e. known family) of virus. Use of the word conforms to best practices for naming new infectious diseases published by the World Health Organization (WHO) in 2015. Historically, pathogens have sometimes been named after locations, individuals, or specific species. However, this practice is now explicitly discouraged by the WHO.
