ICoronavirus yeye-coronavirus ye-coronaviridae ye-Nidovirales kuhlelo olucwangcisiweyo. IiCoronavirus ziintsholongwane zeRNA ezinemvulophu kunye nelinear single strand positive strand genome. Baludidi olukhulu lweentsholongwane ezikhoyo kwindalo.
ICoronavirus inobubanzi obumalunga ne-80 ~ 120 nm, i-methylated cap structure kwi-5 'end of genome kunye ne-poly (a) umsila ekupheleni kwe-3′. Ubude obupheleleyo be-genome malunga ne-27-32 KB. Yeyona ntsholongwane inkulu kwiintsholongwane zeRNA ezaziwayo.
ICoronavirus yosulela kuphela izilwanyana ezinethambo lomqolo, ezinjengabantu, iimpuku, iihagu, iikati, izinja, iingcuka, iinkukhu, iinkomo kunye neenkukhu.
ICoronavirus yaqala ukubekwa yodwa kwiinkukhu ngo-1937. Ubukhulu bentsholongwane yi-60 ~ 200 nm, kunye nobubanzi obuyi-100 nm. Ingqukuva okanye i-oval kwaye ine-pleomorphism. Intsholongwane inemvulophu, kwaye kukho iinkqubo ezijikelezayo kwimvulophu. Intsholongwane yonke ifana necorona. Iinkqubo ze-spinous zee-coronavirus ezahlukeneyo ngokucacileyo zahlukile. Imizimba ye-tubular ebandakanya ngamanye amaxesha inokubonwa kwiiseli ezosulelekileyo yi-coronavirus.
Inoveli coronavirus ka-2019 (2019 ncov, ebangela inoveli coronavirus inyumoniya covid-19) yicoronavirus eyaziwayo yesixhenxe enokosulela abantu. Ezinye ezintandathu yi-hcov-229e, hcov-oc43, HCoV-NL63, hcov-hku1, SARS CoV (ebangela isifo esibukhali sokuphefumla) kunye ne-mers cov (ebangela isifo sokuphefumla kuMbindi Mpuma).
