XE yavumbuwe bwa mbere mu Bwongereza ku ya 15 Gashyantare uyu mwaka.

Mbere ya XE, dukeneye kwiga ubumenyi bwibanze kuri COVID-19. Imiterere ya COVID-19 iroroshye, ni ukuvuga acide nucleic aside wongeyeho proteine ​​shell hanze. Poroteyine ya COVID-19 igabanyijemo ibice bibiri: poroteyine yubatswe na poroteyine idafite imiterere (NSP). Poroteyine zubaka ni ubwoko bune bwa poroteyine S, ibahasha ya poroteyine E, membrane proteine ​​M na proteine ​​nucleocapsid N. Ni poroteyine zikenewe mu gukora virusi. Kuri poroteyine zidafite imiterere, hariho ibirenga icumi. Ni poroteyine zashyizweho na virusi ya virusi kandi zifite imirimo imwe n'imwe mu gihe cyo kwigana virusi, ariko ntizihuza na virusi.

Kimwe mu bintu byingenzi bikurikirana kugirango tumenye aside nucleique (RT-PCR) ni ORF1 a / b igereranya akarere ka COVID-19. Guhinduranya ibintu byinshi ntabwo bigira ingaruka kuri nucleic aside.

Nka virusi ya RNA, COVID-19 ikunda guhinduka, ariko ibyinshi mubihinduka ntacyo bivuze. Bake muribo bazagira ingaruka mbi. Guhindura bike gusa birashobora kongera ubushobozi bwabo bwo kwandura, gutera indwara cyangwa kwirinda indwara.

Ibisubizo by'uruhererekane rwa gene byerekanaga ko ORF1a ya XE yari myinshi muri BA.1 ya Omicron, mugihe ibisigaye biva muri BA.2 ya Omicron, cyane cyane gen zigize igice cya poroteyine - bivuze ko ibiranga kwanduza bishobora kuba hafi ya BA.2. .

BA.2 ni virusi yanduye cyane iboneka mu myaka yashize. Kubwandura bwa endogenous virusi, mubisanzwe tureba R0, ni ukuvuga ko umuntu wanduye ashobora kwanduza abantu benshi badafite ubudahangarwa no kubarinda. Iyo R0 iri hejuru, niko kwandura kwinshi.

Amakuru yambere yerekanaga ko umuvuduko wubwiyongere bwa XE wari hejuru ugereranije na BA.2 wiyongereyeho 10%, ariko nyuma amakuru yerekanaga ko iyi mibare idahagaze neza. Kugeza ubu, ntibishobora kwemezwa ko umuvuduko wacyo wo hejuru ari inyungu zizanwa no kuvugurura.

Byemewe mbere na mbere ko ibikurikira byingenzi bishobora kwandura kurusha BA.2 y'ubu ifite ibyiza byinshi, kandi biragoye guhanura neza uburyo uburozi bwabwo buzahinduka (kwiyongera cyangwa kugabanuka). Kugeza ubu, umubare wibi bintu bishya ntabwo ari byinshi. Ntibishoboka gufata umwanzuro niba hari kimwe muri byo gishobora gutera imbere muburyo bukomeye. Irakeneye gukurikiranirwa hafi. Kubantu basanzwe, nta mpamvu yo guhagarika umutima muri iki gihe. Guhura nibi BA.2 cyangwa birashoboka recombinant variant, inkingo iracyakomeye cyane.

Imbere ya BA ifite imbaraga zikomeye zo guhunga ubudahangarwa 2. Ku bijyanye no gukingirwa bisanzwe (dosiye ebyiri), igipimo cyiza cy’inkingo ebyiri zikoreshwa muri Hong Kong mu gukumira indwara zaragabanutse cyane, ariko ziracyafite imbaraga ingaruka zo gukumira indwara zikomeye n'urupfu. Nyuma yo gukingirwa kwa gatatu, uburinzi bwarushijeho kunozwa.
