I-COUTH ACUTE REPHUPIRACLOCLOCATIRUS 2 (SARS-COV-2), i-pathogen ebabazekayo yesifo sakamuva kakhulu se-coronavirus 2019 (i-Covid-19) i-abhule, ingumqondo omuhle, i-rna ye-rna eyodwa ngosayizi we-genome azungeze ama-30 kb . Ukuhlukahluka okuningi kwe-SARS-Cov-2 okunamasiginesha ahlukile kuqhamuke kulo lonke ubhubhane. Ngokuya nge-spike protein actiational strational shortscape, ezinye izinto ezihlukile zikhombise ukuhanjiswa okuphezulu, ukusetshenziswa kwemali kanye ne-virulence.

I-JN.1 (BA.2.86.1.1) ivele isanda kuvela kwa-SARS-Cov-2 ehlelwe ngoLayini we-BA.2.86. I-JN.1 iqukethe ukuguqulwa okucacile okungu-L455s kumaprotheni we-spike nezinye izinguquko ezintathu kumaprotheni ama-dete. Studies investigating HK.3 and other “FLip” variants have shown that acquiring L455F mutation in the spike protein is associated with increased viral transmissibility and immune evasion ability. I-L455F kanye ne-F456L Deations babizwa ngokuthi "Flip "Izakhi zofuzo ngoba ziguqula izikhundla zama-amino acid amabili, abhalwe u-F no-l, kumaprotheni weSpike.

We Medical Medical Convotion singanikeza isivivinyo se-Covid-19 sokuzivivinya kwasekhaya, Siyakwamukela ukuxhumana nathi ukuthola eminye imininingwane.
