ICoronavirus yeye-coronavirus ye-coronaviridae ye-Nidovirales kuhlelo olucwangcisiweyo.IiCoronavirus ziintsholongwane ze-RNA ezinemvulophu kunye nemigca enye ene-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 ze-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).
