Coronavirus ndi wa coronavirus wa coronaviridae wa Nidovirales m'gulu mwadongosolo. Ma Coronaviruses ndi ma virus a RNA okhala ndi envulopu ndi mzere umodzi wa strand positive strand genome. Iwo ndi gulu lalikulu la mavairasi ambiri alipo mu chilengedwe.
Coronavirus ali ndi m'mimba mwake pafupifupi 80 ~ 120 nm, kapu ya methylated kumapeto kwa genome ndi poly (a) mchira kumapeto kwa 3′. Kutalika konse kwa genome ndi pafupifupi 27-32 KB. Ndilo kachilombo kakang'ono kwambiri mwa ma virus odziwika a RNA.
Coronavirus amangokhudza zamoyo zamsana, monga anthu, makoswe, nkhumba, amphaka, agalu, mimbulu, nkhuku, ng'ombe ndi nkhuku.
Coronavirus idalekanitsidwa koyamba ndi nkhuku mu 1937. The awiri a tizilombo particles ndi 60 ~ 200 nm, ndi awiri avareji 100 nm. Ndi yozungulira kapena yozungulira ndipo ili ndi pleomorphism. Kachilombo kameneka kali ndi envelopu, ndipo pali njira zozungulira pa envelopu. Vuto lonseli lili ngati corona. Njira za spinous za ma coronavirus osiyanasiyana ndizosiyana. Matupi ophatikizika a tubular nthawi zina amatha kuwoneka m'maselo omwe ali ndi kachilombo ka coronavirus.
Coronavirus buku la 2019 (2019 ncov, lomwe limayambitsa buku la coronavirus chibayo covid-19) ndi coronavirus yachisanu ndi chiwiri yodziwika yomwe imatha kupatsira anthu. Zina zisanu ndi chimodzi ndi hcov-229e, hcov-oc43, HCoV-NL63, hcov-hku1, SARS CoV (yoyambitsa matenda oopsa kwambiri a kupuma) ndi mers cov (oyambitsa matenda a kupuma ku Middle East).
