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 zvakatenderera kana elliptic, kazhinji pleomorphic, ine dhayamita ye60 ~ 140nm, uye maitiro ayo emajini akasiyana zvakanyanya neaya eSARSr-CoV neMERSr-CoV. mabayo, kutadza kufema, acute respiratory distress syndrome, septic shock, kutadza kwenhengo dzakawanda, kuomarara kweasidhi-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). Hutachiona hunonzwa nechiedza che ultraviolet uye kupisa, uye hunogona kunyatso kuvharwa ne56 ℃ kwemaminetsi makumi matatu kana lipid solvents senge ethyl ether, 75% ethanol, chlorine-containing disinfectant, peroxyacetic acid uye chloroform.
