I-SARS-CoV-2isanvelopedβ-coronavirus, i-circularorellipticalparticlediameterofabout60 ~ 140nm, ihlala i-pleomorphic, ngokucacileyo yahlukile kwi-SARS-CoVandMERS-CoVingeneticcharacteristics. Iquka umkhuhlane, ukudinwa kunye nezinye iimpawu zenkqubo, ezikhatshwa lukhohlokhohlo, ukuphelelwa umoya, njalo njalo, ezinokukhula ngokukhawuleza kwinyumoniya enzima, ukusilela kokuphefumla, isifo sokuphefumla esibuhlungu, ukothuka, ukusilela kwamalungu amaninzi, zintlanu Isifo se-reasidi-basemetabolism, kwanobomi esichengeni.I-SARS-CoV-2 ichongiwe njengesixhobo sokuphefumla ngamathontsi okuphefumla( ukuthimla, ukukhohlela, njalo njalo) kunye nokunxibelelana i-hthevirus,i-rubbingeyes,njl.).I-SARS-CoV-2iyingozi kwi-ultravioletrayandheat,kwaye inokunganyanzelwa kuma-56℃imizuzu engama-30kunye nefatsolublesolventsuchasethylether,75%ethanol,i-chlorinedisinfectant,peraceticacidandchloroform.
