Novel coronavirus (nCoV) is a provisional name given to coronaviruses of medical significance before a permanent name is decided upon. Although coronaviruses are endemic in humans and infections normally mild, such as the common cold (caused by human coronaviruses in ~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 and death.
The following viruses could initially be referred to as "novel coronavirus", before being formally named:
|Official name||Other names||Original host[a]||Place (date) of discovery||Disease caused|
|Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)[b]||2019-nCoV; SARS virus 2; Human coronavirus 2019 (HCoV-19)||pangolins, bats||Wuhan, China (2019)||coronavirus disease 2019 (COVID-19)[c]|
|Middle East respiratory syndrome–related coronavirus (MERS-CoV)[d]||Middle East virus; MERS virus; camel flu virus||camels, bats||Jeddah, Saudi Arabia (2012)||Middle East respiratory syndrome (MERS)|
|Human coronavirus HKU1 (HCoV-HKU1)||New Haven virus||mice||Hong Kong (2005)||unnamed, extremely rare, usually mild variant of coronavirus respiratory syndrome|
|Severe acute respiratory syndrome coronavirus (SARS-CoV-1)[b]||SARS virus||civets, bats||Foshan, China (2002)||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. A study published in 2020 suggested that referring to the novel coronavirus (COVID-19) as the "Chinese virus" was stigmatizing and could hinder public health efforts.
