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- 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 pneumonia e matla, ho hloleha ho hema, lefu le matla la ho hema, ho tsieleha ha septic, ho hloleha ha litho tse ngata, acid e matla. -base metabolic disorder, 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.).
