Kab mob ua pa hnyav heev coronavirus 2 (SARS-CoV-2), tus kab mob ua rau muaj tus kab mob coronavirus tshiab tshaj plaws xyoo 2019 (COVID-19), yog tus kab mob RNA ib txoj hlua zoo nrog qhov loj ntawm genome li ntawm 30 kb. Ntau hom SARS-CoV-2 nrog cov cim hloov pauv sib txawv tau tshwm sim thoob plaws hauv kev sib kis. Nyob ntawm lawv cov toj roob hauv pes hloov pauv protein, qee hom tau qhia txog kev sib kis, kev sib kis, thiab kev sib kis kab mob siab dua.

Cov noob caj noob ces BA.2.86 ntawm SARS-CoV-2, uas tau txheeb xyuas thawj zaug thaum Lub Yim Hli 2023, yog qhov sib txawv ntawm cov noob caj noob ces Omicron XBB uas tam sim no ncig, suav nrog EG.5.1 thiab HK.3. Cov noob caj noob ces BA.2.86 muaj ntau dua 30 qhov kev hloov pauv hauv cov protein spike, qhia tias cov noob caj noob ces no muaj peev xwm zam tau qhov kev tiv thaiv kab mob SARS-CoV-2 uas twb muaj lawm.

Tus JN.1 (BA.2.86.1.1) yog tus kab mob SARS-CoV-2 uas nyuam qhuav tshwm sim los ntawm cov noob caj noob ces BA.2.86. Tus JN.1 muaj qhov kev hloov pauv tseem ceeb L455S hauv cov protein spike thiab peb qhov kev hloov pauv ntxiv hauv cov protein uas tsis yog spike. Cov kev tshawb fawb tshawb nrhiav HK.3 thiab lwm yam "FLip" variants tau qhia tias kev tau txais L455F kev hloov pauv hauv cov protein spike yog txuam nrog kev kis tus kab mob ntau ntxiv thiab kev tiv thaiv kab mob. Cov kev hloov pauv L455F thiab F456L yog lub npe menyuam yaus "Tigkev hloov pauv vim tias lawv hloov qhov chaw ntawm ob lub amino acids, uas muaj npe F thiab L, ntawm cov protein spike.
