MaCoronavirus ndeeNidovirales,Coronavirusidae neCoronavirus. Rudzi rukuru rwemavhairasi anowanikwa zvakanyanya. Mavhairasi e5 'ekupedzisira kweboka remavhairasi ane chimiro cheA methylated cap, uye magumo e3' ane muswe weA poly (A), genome racho raive rakareba 27-32kb. Ndiro vhairasi reRNA rakakura kwazvo rinozivikanwa rine genome rakakura. Mavhairasi eCoronavirus akakamurwa kuita marudzi matatu: α,β, γ.α,β chete mhuka dzinoyamwisa, γ inonyanya kukonzera kutapukirwa kweshiri. CoV yakaratidzwawo kuti inotapuriranwa kunyanya kuburikidza nekubata zvakananga nezvinobuda kana kuburikidza neaerosols nemadonhwe, uye yakaratidzwa kuti inotapuriranwa kuburikidza nenzira yetsvina nemuromo. Mavhairasi eCoronavirus ane chekuita nezvirwere zvakasiyana-siyana muvanhu nemhuka, zvichikonzera zvirwere zvekufema, zvekugaya uye zvetsinga muvanhu nemhuka. SARS-CoV-2 ndeye β coronavirus, iyo yakaputirwa, uye zvidimbu zvacho zvakatenderera kana kuti zvakatenderera, zvinowanzoita pleomorphic, ine dhayamita ye60~140nm, uye hunhu hwayo hwemajini hwakasiyana zvakanyanya nehweSARSr-CoV neMERSr-CoV. Zviratidzo zvekiriniki ifivha, kuneta nezvimwe zviratidzo zvemuviri, zvinoperekedzwa nekukosora kwakaoma, kushaya simba, nezvimwewo, zvinogona kukura nekukurumidza kuita pneumonia yakanyanya, kutadza kufema, acute respiratory distress syndrome, septic shock, multi-organ failure, severe acid-base metabolic disorder, uye kunyange kutyisidzira hupenyu. Kutapurirana kweSARS-CoV-2 kwakaonekwa zvakanyanya kuburikidza nemadonhwe ekufema (kuhotsira, kukosora, nezvimwewo) uye kutapurirana kwekubata (kutora mhino, kukwesha maziso, nezvimwewo). Virusi iyi inonzwa chiedza che ultraviolet nekupisa, uye inogona kushaikwa ne56℃ kwemaminitsi makumi matatu kana lipid solvents dzakadai se ethyl ether, 75% ethanol, chlorine-containing disinfectant, peroxyacetic acid uye chloroform.
