摘要: Four coronaviruses (HCoV-229E, HCoV-OC43, HCoV-NL63, HCoV-HKU1) are endemic in humans and mainly associated with mild respiratory illnesses; whereas the other two [Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) Middle East (MERS-CoV)] present as emerging infections causing severe syndrome. Coronaviruses evolve by accumulation of point mutations recombination genomes among different strains or species. Mammalian including those infect evolved from bat coronaviruses. While SARS-CoV MERS-CoV genetically closely related to coronaviruses, intermediate host(s) is (are) likely be involved emergence cross-species transmission these novel human viruses. High prevalence SARS-like have been found masked palm civet cats raccoon dogs collected markets around time outbreaks humans, but animals a transient accidental host rather than persisting reservoir. More research needed elucidate ecology Vigilance surveillance should maintained promptly identify newly emerged
