ISIFINYEZO

Ama-Coronavirus angaphansi kwe-Nidovirales, i-Coronavirus kanye ne-Coronavirus. Uhlobo olukhulu lwamagciwane atholakala kabanzi emvelweni. Ukuphela okungu-5 'kweqembu legciwane kunesakhiwo se-A methylated cap, kanti ukuphela okungu-3' kunomsila we-A poly (A), i-genome yayingama-27-32kb ubude. Yigciwane le-RNA elikhulu kunawo wonke elaziwa kakhulu eline-genome enkulu kunazo zonke. Ama-Coronavirus ahlukaniswe ngezizukulwane ezintathu: i-α, i-β, i-γ.α, i-β kuphela yi-pathogenic ezincelisayo, i-γ iholela kakhulu ekuthelelekeni kwezinyoni. I-CoV nayo yabonakala ukuthi idluliselwa ikakhulukazi ngokuxhumana ngqo noketshezi noma ngama-aerosol namaconsi, futhi kuye kwabonakala ukuthi idluliselwa ngendlela yendle-yomlomo. Ama-Coronavirus ahlotshaniswa nezifo ezahlukahlukene kubantu nasezilwaneni, okubangela izifo zesistimu yokuphefumula, yokugaya ukudla kanye neyezinzwa kubantu nasezilwaneni. I-SARS-CoV-2 ingeyohlobo lwe-β coronavirus, olumbozwe, futhi izinhlayiya ziyindilinga noma ziyi-elliptic, ngokuvamile zi-pleomorphic, ububanzi obungu-60 ~ 140nm, futhi izici zayo zofuzo zihluke kakhulu kweze-SARSr-CoV kanye ne-MERSr-CoV. Izimpawu zomtholampilo umkhuhlane, ukukhathala kanye nezinye izimpawu zomzimba, ezihambisana nokukhwehlela okomile, ukuphefumula, njll., okungakhula ngokushesha kube yi-pneumonia enzima, ukwehluleka kokuphefumula, i-acute respiratory distress syndrome, i-septic shock, ukwehluleka kwezitho eziningi, ukuphazamiseka okukhulu kwe-acid-base metabolic, ngisho nokusongela impilo. Ukudluliswa kwe-SARS-CoV-2 kutholakale ikakhulukazi ngamaconsi okuphefumula (ukuthimula, ukukhwehlela, njll.) kanye nokudluliswa kokuxhumana (ukukhetha ikhala, ukuhlikihla amehlo, njll.). Igciwane lizwela ekukhanyeni kwe-ultraviolet nokushisa, futhi lingavinjelwa ngempumelelo yi-56℃ imizuzu engama-30 noma izinyibilikisi ze-lipid ezifana ne-ethyl ether, i-ethanol engu-75%, isibulala-magciwane esiqukethe i-chlorine, i-peroxyacetic acid kanye ne-chloroform
