ISIFINYEZO

AmaCoronavirus angaphansi kweNidovirales, Coronaviridae kanye neCoronavirus Isigaba esikhulu samagciwane atholakala kabanzi emvelweni. Isiphetho esingu-5 'seqembu legciwane sinesakhiwo sekepisi esine-methylated, kanti isiphetho esingu-3' sinomsila ongu-A poly (A), i-genome yayingama-27-32kb ubude. Igciwane le-RNA elikhulu kunawo wonke elaziwayo elinegenome elikhulu kunawo wonke.Ama-Coronavirus ahlukaniswe izigaba ezintathu: α,β, γ.α,β kuphela isilwane esincelisayo esincelisayo, u-γ uholela kakhulu ezifweni zezinyoni. I-CoV iphinde yaboniswa ukuthi isakazwa ikakhulukazi ngokuthintana okuqondile nezimfihlo noma ngama-aerosol namaconsi, futhi kuboniswe ukuthi isakazwa ngomzila we-fecal-oral. AmaCoronavirus ahlotshaniswa nezinhlobonhlobo zezifo kubantu nasezilwaneni, okubangela izifo zesimiso sokuphefumula, sokugaya ukudla kanye nezinzwa kubantu nasezilwaneni. I-SARS-CoV-2 ingeye-β coronavirus, embozwe, futhi izinhlayiya ziyindilinga noma ziyi-elliptic, ngokuvamile i-pleomorphic, enobubanzi obungu-60 ~ 140nm, futhi izici zayo zofuzo zihluke kakhulu kulezo ze-SARSr-CoV kanye ne-MERSr- I-CoV. Ukubonakaliswa komtholampilo umkhuhlane, ukukhathala nezinye izimpawu zesistimu, okuhambisana nokukhwehlela okomile, i-dyspnea, njll., okungakhula ngokushesha kube inyumoniya enzima, ukwehluleka ukuphefumula, isifo sokucindezeleka kokuphefumula, ukushaqeka kwe-septic, ukwehluleka kwezitho eziningi, i-asidi enamandla. -i-base metabolic disorder, ngisho nokubeka impilo engcupheni. Ukudluliselwa kwe-SARS-CoV-2 kukhonjwe ikakhulukazi ngamaconsi okuphefumula (ukuthimula, ukukhwehlela, njll.) kanye nokudluliselwa kokuxhumana (ukucosha ikhala, ukuhlikihlwa iso, njll.). Igciwane liyazwela ekukhanyeni kwe-ultraviolet kanye nokushisa, futhi lingakwazi ukusebenza ngempumelelo ngo-56 ℃ imizuzu engu-30 noma izincibilikisi ze-lipid ezifana ne-ethyl ether, i-ethanol engu-75%, isibulala-magciwane esine-chlorine, i-peroxyacetic acid ne-chloroform.
