I-COUSH ACUTE ACUTEMURIRACLOPS SPRONOME CORONAVIRUS 2 (SARS-Cov-2), i-pathogen ebabazekayo yesifo sakamuva kakhulu se-coronavirus 2019 (i-Covid-19), ingumqondo omuhle, i-rna ye-rna eyodwa enosayizi we-genome ezungeze 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-Ba.2.86 LINEAGE ye-SARS-Cov-2, eyayiqala ukubonwa ngo-Agasti 2023, ihlukile ngokujikeleza kwamanje kuma-Omicron XBB uLineeges, kufaka phakathi i-EG.5.1 ne-HK.3. I-Lineage ye-BA.2.86 iqukethe izinguquko ezingaphezu kuka-30 kumaprotheni weSpike, okukhombisa ukuthi le nhlanganisela iyakwazi ukugwema ama-anti-sars akhona wangaphambi kokuba akhona - i-cov-2.

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. Ucwaningo luphenya ama-HK.3 kanti okunye "kwe-Flip" okuhlukahlukene kukhombisile ukuthi ukuthola ukuguqulwa kwe-L455f ku-Spike Protein kuhlotshaniswa nokutholwa kwegciwane le-Spike nekhono lokuzivikela komzimba. 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.
