IiCoronavirus zezeNidovirales, Coronaviridae kunye neCoronavirus Udidi olukhulu lweentsholongwane ezifumaneka ngokubanzi kwindalo.I-5 'isiphelo seqela lentsholongwane ine-A methylated cap structure, kunye ne-3'siphelo ine-A poly (A) umsila, i-genome yayiyi-27-32kb ubude.Yeyona ntsholongwane inkulu eyaziwayo ye-RNA ene-genome enkulu.I-Coronaviruses zohlulwe ngokwemigangatho emithathu: α,β, γ.α,β kuphela isilwanyana esanyisayo, i-γ ikhokelela ikakhulu kusulelo lweentaka.I-CoV ikwabonakaliswe ukuba yosulela ikakhulu ngokunxibelelana ngokuthe ngqo neemfihlo okanye ngee-aerosols kunye namathontsi, kwaye ibonakaliswe ukuba isasazwa ngendlela ye-fecal-oral.IiCoronavirus zinxulunyaniswa neentlobo ngeentlobo zezifo ebantwini nakwizilwanyana, ezibangela izifo zokuphefumla, zokwetyisa kunye nenkqubo yemithambo-luvo ebantwini nakwizilwanyana.I-SARS-CoV-2 yeye-β coronavirus, egqunyiweyo, kwaye amasuntswana angqukuva okanye ayi-elliptic, ahlala e-pleomorphic, enobubanzi obuyi-60 ~ 140nm, kwaye iimpawu zayo zemfuza zahluke kakhulu kwezo ze-SARSr-CoV kunye ne-MERSr- Izibonakaliso zeklinikhi ngumkhuhlane, ukudinwa kunye nezinye iimpawu zenkqubo, ezihamba nokhohlokhohlo olomileyo, i-dyspnea, njl., enokuthi ikhule ngokukhawuleza ibe yinyumoniya enzima, ukusilela kokuphefumla, isifo sokuphefumla kakhulu, ukothuka kwe-septic, ukusilela kwamalungu amaninzi, iasidi eqatha. -isiseko sokuphazamiseka kwemetabolism, kwaye kwanokubeka ubomi esichengeni.Usulelo lwe-SARS-CoV-2 ichongiwe ikakhulu ngamathontsi okuphefumla (ukuthimla, ukukhohlela, njl.njl.) kunye nokuhanjiswa koqhagamshelwano (ukuchola impumlo, ukuhlikihlwa kwamehlo, njl. njl.).Intsholongwane inovelwano kukukhanya kwe-ultraviolet kunye nobushushu, kwaye inokuthi isebenze ngokufanelekileyo ngu-56 ℃ imizuzu engama-30 okanye izinyibilikisi ze-lipid ezifana ne-ethyl ether, i-75% ye-ethanol, i-chlorine equkethe isibulala-zintsholongwane, i-peroxyacetic acid kunye ne-chloroform.
