Li-Coronaviruses ke tsa Nidovirales, Coronaviridae le Coronavirus Sehlopha se seholo sa livaerase tse fumanehang haholo tlhahong. Qetello ea 5 ea sehlopha sa vaerase e na le sebopeho sa cap ea methylated, 'me pheletso ea 3' e na le mohatla oa A poly (A), genome e ne e le bolelele ba 27-32kb. Ke kokoana-hloko e kholo ka ho fetisisa e tsejoang ea RNA e nang le genome e kholo ka ho fetisisa.Coronaviruses e arotsoe ka lihlopha tse tharo: α,β, γ.α,β feela phoofolo e anyesang ea pathogenic, γ e lebisa haholo ho tšoaetso ea linonyana. CoV e boetse e bonts'itsoe hore e fetisoa haholo-holo ka ho kopana ka kotloloho le li-secretions kapa ka li-aerosols le marotholi, 'me ho bonts'itsoe hore e fetisoa ka tsela ea molomo. Li-Coronavirus li amahanngoa le mefuta e fapaneng ea mafu bathong le liphoofolong, a bakang mafu a tsamaiso ea ho hema, ea tšilo ea lijo le ea methapo bathong le liphoofolong. SARS-CoV-2 ke ea β coronavirus, e koahetsoeng, 'me likaroloana li pota-potile kapa li elliptic, hangata li pleomorphic, ka bophara ba 60 ~ 140nm,' me liphatsa tsa lefutso tsa eona li fapane haholo le tsa SARSr-CoV le MERSr- CoV. Lipontšo tsa kliniki ke feberu, mokhathala le matšoao a mang a tsamaiso, a tsamaeang le ho khohlela ho omileng, dyspnea, joalo-joalo, e ka fetohang ka potlako ho ba matla. nyumonia, ho hloleha ho phefumoloha, lefu le matla la ho hema, lefu la septic shock, ho se sebetse hantle ha litho tse ngata tsa 'mele, bothata bo matla ba metabolism ea acid-base, esita le ho beha bophelo kotsing. Phetiso ea SARS-CoV-2 e khethiloe haholo-holo ka marotholi a phefumolohang (ho thimola, ho khohlela, joalo-joalo) le phetisetso ea ho ikopanya (ho phunya nko, ho hohla mahlo, jj.). Kokoana-hloko e ela hloko khanya ea ultraviolet le mocheso, 'me e ka etsoa ka katleho ka 56 ℃ ka metsotso e 30 kapa metsoako ea lipid e kang ethyl ether, 75% ethanol, chlorine-containing disinfectant, peroxyacetic acid le chloroform.
