Indwara ya coronavirus 2 (SARS-CoV-2), indwara itera icyorezo cya coronavirus 2019 (COVID-19), ni virusi ya RNA ifite imiterere imwe, ifite ingano ya genome ingana na kilobe 30. Ubwoko bwinshi bwa SARS-CoV-2 bufite ibimenyetso bitandukanye bya mutation bwagaragaye mu gihe cyose cy'icyorezo. Bitewe n'imiterere ya poroteyine mutation, ubwoko bumwe bwagaragaje ko bwandurira cyane, ko bwandurira mu buryo bukabije, kandi ko bushobora kwanduzanya.

Urutonde rwa BA.2.86 rwa SARS-CoV-2, rwagaragaye bwa mbere muri Kanama 2023, rutandukanye cyane n'ubwoko bwa Omicron XBB buriho ubu, harimo EG.5.1 na HK.3. Urutonde rwa BA.2.86 rugizwe n'impinduka zirenga 30 muri poroteyine ya spike, bigaragaza ko uru rutonde rufite ubushobozi bwo kwirinda ubudahangarwa bwa SARS-CoV-2 bwari busanzweho.

JN.1 (BA.2.86.1.1) ni yo nkomoko iheruka kugaragara ya SARS-CoV-2 yakomotse ku muryango wa BA.2.86. JN.1 irimo impinduka ikomeye ya L455S muri poroteyine ya spike n'izindi mpinduka eshatu muri poroteyine zitari spike. Ubushakashatsi bwakozwe ku bushakashatsi bwa HK.3 n'ubundi bwoko bwa "FLip" bwagaragaje ko kubona impinduka ya L455F muri poroteyine ya spike bifitanye isano no kwiyongera kwa virusi no kwirinda ubudahangarwa bw'umubiri. Impinduka za L455F na F456L zitwa """Hindura"impinduka kuko zihindura imyanya ya aside amine ebyiri, zanditseho F na L, kuri poroteyine yo mu bwoko bwa spike.

Twebwe baysen medical dushobora gutanga isuzuma rya COVID-19 ku giti cyacu kugira ngo dukoreshwe mu rugo, murakaza neza kutwandikira kugira ngo mumenye byinshi.
