Coronavirus belongs rau tus mob coronavirus ntawm coronaviridae ntawm Nidovirales hauv kev faib tawm. Coronaviruses yog cov kab mob RNA nrog lub hnab ntawv thiab cov kab ib kab kab zoo genome. Lawv yog ib pawg loj ntawm cov kab mob uas muaj nyob rau hauv qhov xwm txheej.
Coronavirus muaj txoj kab uas hla ntawm 80 ~ 120 nm, methylated cap qauv ntawm 5' kawg ntawm genome thiab poly (a) tail ntawm 3′ kawg. Tag nrho qhov ntev ntawm genome yog li 27-32 KB. Nws yog tus kab mob loj tshaj plaws hauv cov kab mob RNA paub.
Tus mob Coronavirus tsuas kis tus kab mob vertebrates, xws li tib neeg, nas, npua, miv, dev, hma, qaib, nyuj thiab nqaij qaib.
Coronavirus yog thawj zaug cais tawm ntawm qaib hauv xyoo 1937. Lub cheeb ntawm cov kab mob yog 60 ~ 200 nm, nrog qhov nruab nrab txoj kab uas hla ntawm 100 nm. Nws yog spherical los yog oval thiab muaj pleomorphism. Tus kab mob muaj ib lub hnab ntawv, thiab muaj cov txheej txheem spinous ntawm lub hnab ntawv. Tag nrho tus kab mob zoo li corona. Cov txheej txheem spinous ntawm cov kab mob coronaviruses sib txawv yog pom tseeb. Tubular suav nrog lub cev qee zaum tuaj yeem pom hauv cov kab mob coronavirus.
2019 Novel Coronavirus (2019 ncov , ua rau muaj tus kabmob tshiab pneumonia covid-19 ) yog xya tus kabmob coronavirus uas tuaj yeem kis tau rau tib neeg. Lwm qhov yog hcov-229e, hcov-oc43, HCoV-NL63, hcov-hku1, SARS CoV (ua rau mob hnyav ua pa nyuaj) thiab mers cov (ua rau Middle East respiratory syndrome).
