Coronavirus ndeye coronavirus yecoronaviridae yeNidovirales muhurongwa hwakarongeka. Coronaviruses mavhairasi eRNA ane hamvuropu uye linear single strand positive strand genome. Iwo ikirasi hombe yemavhairasi aripo zvakanyanya mune zvakasikwa.
Coronavirus ine dhayamita ingangoita 80 ~ 120 nm, methylated cap chimiro pa5 'kumagumo ejenome uye poly (a) muswe kumagumo e3'. Hurefu hwakazara hwe genome hunosvika 27-32 KB. Ndihwo hutachiona hukuru mumavhairasi anozivikanwa eRNA.
Coronavirus inongobata mhuka dzine mapfupa emuzongoza, dzakaita sevanhu, makonzo, nguruve, katsi, imbwa, mapere, huku, mombe nehuku.
Coronavirus yakatanga kuparadzaniswa nehuku muna 1937. The diameter of virus particles is 60 ~ 200 nm, ine avhareji yedhayamita ye100 nm. Iine denderedzwa kana kuti oval uye ine pleomorphism. Utachiona hune hamvuropu, uye pane spinous maitiro pahamvuropu. Hutachiona hwese hwakafanana nekorona. Iyo spinous maitiro eakasiyana coronaviruses ari pachena akasiyana. Tubular inosanganisirwa miviri inogona dzimwe nguva kuoneka mumaseru ane hutachiona hwe coronavirus.
2019 novel coronavirus (2019 ncov, ichikonzera novel coronavirus pneumonia covid-19) ndiyo yechinomwe inozivikanwa coronavirus inogona kutapurira vanhu. Mamwe matanhatu ndeaya hcov-229e, hcov-oc43, HCoV-NL63, hcov-hku1, SARS CoV (inokonzeresa yakanyanya acute respiratory syndrome) uye mers cov (inokonzeresa Middle East Respiratory Syndrome).
