ICoronavirus ingeye-coronavirus ye-coronaviridae yase-Nidovirales ngokwezigaba ezihlelekile.Ama-Coronaviruses angamagciwane e-RNA anemvilophu kanye ne-linear single strand positive strand genome.Bayisigaba esikhulu samagciwane akhona kabanzi emvelweni.
ICoronavirus inobubanzi obungu-80 ~ 120 nm, ukwakheka kwekepisi ene-methylated ekugcineni kwe-genome engu-5 kanye nomsila we-poly (a) ekugcineni kuka-3′.Ubude obuphelele be-genome cishe bungama-27-32 KB.Yigciwane elikhulu kunawo wonke kumagciwane aziwayo e-RNA.
ICoronavirus ihlasela kuphela izilwane ezinomgogodla, njengabantu, amagundane, izingulube, amakati, izinja, izimpisi, izinkukhu, izinkomo nezinkukhu.
ICoronavirus yaqala ukuhlukaniswa nezinkukhu ngo-1937. Ububanzi bezinhlayiya zegciwane buyi-60 ~ 200 nm, nobubanzi obuyi-100 nm.Iyisiyingi noma i-oval futhi ine-pleomorphism.Igciwane linemvilophu, futhi kunezinqubo ezi-spinous emvilophini.Igciwane lonke lifana ne-corona.Izinqubo ze-spinous zama-coronavirus ahlukene ngokusobala zihlukile.Izidumbu zokufakwa kwamashubhu kwesinye isikhathi zingabonakala kumaseli angenwe yi-coronavirus.
I-coronavirus ka-2019 (2019 ncov, ebangela inoveli i-coronavirus pneumonia covid-19) iyi-coronavirus yesikhombisa eyaziwayo engathelela abantu.Ezinye eziyisithupha i-hcov-229e, hcov-oc43, HCoV-NL63, hcov-hku1, SARS CoV (edala i-acute acute kupumua syndrome) kanye ne-mers cov (okubangela i-Middle East Respiratory Syndrome).
