I-SARS-CoV-2 i-β-coronavirus eneentsholongwane ze-coronavirus, ububanzi be-circular okanye i-elliptical particle obumalunga ne-60 ~ 140nm, idla ngokuba yi-pleomorphic, ngokucacileyo yahlukile kwi-SARS-CoVandMERS-CoVingenetic. Iimpawu eziphambili zeklinikhi ziquka umkhuhlane, ukudinwa kunye nezinye iimpawu zenkqubo, ezihamba nokukhwehlela okomileyo, ukuphelelwa ngamandla, njl.njl., ezinokukhula ngokukhawuleza zibe yi-pneumonia enzima, ukusilela kokuphefumla, isifo soxinzelelo lokuphefumla esibuhlungu, ukushaqeka kwe-septic, ukusilela kwamalungu amaninzi, seve i-reacid-basemetabolism disorder, kwaye isongela ubomi. I-SARS-CoV-2 ichongiwe njengeyona ndlela iphambili yokudluliselwa ngamaconsi okuphefumla (ukuthimla, ukukhohlela, njl.njl.) kunye nokunxibelelana (ukukhetha ikhala kunye nesandla xa udibana nentsholongwane, amehlo acocayo, njl.njl.). I-SARS-CoV-2 ibuthathaka kwi-ultravioletraya kunye nobushushu, kwaye ingasetyenziswa kwi-56℃ kangangemizuzu engama-30 kwaye ngamafutha anyibilikayo njenge-ethylethylether, i-75% ye-ethanol, i-chlorine disinfectant, i-peraceticacid kunye ne-chloroform.
