SUMMARY

Coronaviruses ndeeNidovirales, Coronaviridae neCoronavirus Kirasi hombe yemavhairasi inowanikwa zvakanyanya muzvisikwa.Iyo 5 'kuguma kweboka rehutachiona ine A methylated cap chimiro, uye iyo 3' kuguma ine A poly (A) muswe, iyo genome yaive 27-32kb kureba.Ndihwo hutachiwana hweRNA hukuru kwazvo hune genome hombe.Coronaviruses dzakakamurwa kuita zvizvarwa zvitatu: α,β, γ.α,β chete inoyamwisa pathogenic, γ inonyanya kutungamira kuzvirwere zveshiri.CoV yakaratidzwawo kuti inotapuriranwa zvakanyanya kuburikidza nekusangana kwakananga nekuvanzika kana kuburikidza neaerosols uye madonhwe, uye yakaratidza kufambiswa nenzira yefecal-yemuromo.Coronaviruses inosanganiswa nemhando dzakasiyana dzezvirwere muvanhu nemhuka, zvichikonzera zvirwere zvekufema, kugaya uye tsinga muvanhu nemhuka.SARS-CoV-2 ndeye β coronavirus, iyo yakafukidzwa, uye zvimedu zvakatenderedza kana elliptic, kazhinji pleomorphic, ine dhayamita ye60 ~ 140nm, uye maitiro ayo emajini akasiyana zvakanyanya neaya eSARSr-CoV neMERSr- CoV.Makiriniki anoratidzwa fivha, kuneta uye zvimwe zviratidzo zvehurongwa, zvichiperekedzwa nekuoma kwechikosoro, dyspnea, nezvimwe, izvo zvinogona kukurumidza kukura kuita mabayo akanyanya, kutadza kufema, acute kufema kunetseka syndrome, septic shock, kutadza kwenhengo dzakawanda, acid yakanyanya. - base metabolic disorder, uye kunyange kutyisidzira upenyu.Kutapurirana kweSARS-CoV-2 kwakaonekwa zvakanyanya kuburikidza nemadonhwe ekufema (kutsveta, kukosora, nezvimwewo) uye kutapurirana (kunhonga mhino, kukwesha ziso, nezvimwewo).Utachiona hunonzwa kuchiedza che ultraviolet uye kupisa, uye hunogona kuvharwa zvakanaka ne56 ℃ kwemaminitsi makumi matatu kana lipid solvents se ethyl ether, 75% ethanol, chlorine-containing disinfectant, peroxyacetic acid uye chloroform.
