Impinduka nshya ya Omicron BA.2 yakwirakwiriye mu bihugu 74! Inyigo isanga: Ikwirakwira vuba kandi ifite ibimenyetso bikomeye

Impinduka nshya kandi yanduye kandi iteje akaga ya Omicron, kuri ubu yitwa Omicron BA.2 subtype variant, yagaragaye nayo ifite akamaro ariko ntiganirwaho cyane kuruta uko byagenze muri Ukraine. . ariko indwara ya ba.2 iriyongera.)

BUPA yizera ko ihungabana rikomeye ku masoko mpuzamahanga mu minsi yashize biterwa no kuba ibintu byifashe nabi muri Ukraine, kandi indi mpamvu ni uburyo bushya bwa Omicron, ubwoko bushya bwa virusi iki kigo cyizera ko kigenda cyiyongera kandi kikaba ari nde? Ingaruka ya macro ku bukungu bwisi irashobora kuba ingenzi kuruta uko muri Ukraine.

Nk’uko ubushakashatsi buheruka gukorwa muri kaminuza ya Tokiyo mu Buyapani bubivuga, ubwoko bwa BA.2 butagaragara gusa bukwirakwira vuba ugereranije na COVID-19 yiganje muri iki gihe, Omicron BA.1, ariko kandi bushobora no gutera uburwayi bukomeye kandi bigaragara ko bushobora kuburizamo. zimwe mu ntwaro z'ingenzi dufite zo kurwanya COVID-19.

Abashakashatsi banduye hamsters hamwe na BA.2 na BA.1, basanga abanduye BA.2 barwaye kandi bakangiza cyane ibihaha. Abashakashatsi basanze BA.2 ishobora no kuzenguruka zimwe muri antibodies zakozwe nuru rukingo kandi ikaba ishobora kurwanya imiti imwe n'imwe ivura.

Abashakashatsi b'ubwo bushakashatsi bagize bati: “Ubushakashatsi bwo kutabogama bwerekana ko ubudahangarwa buterwa n'inkingo budakora neza kuri BA.2 nk'uko bukora kuri BA.1.”

Ibibazo bya virusi ya BA.2 byagaragaye mu bihugu byinshi, kandi Ishami ry'Umuryango w'Abibumbye ryita ku Buzima rivuga ko BA.2 yanduye hafi 30 ku ijana ugereranije na BA.1 y'ubu, iboneka mu bihugu 74 na Leta 47 zo muri Amerika.

Iyi virusi ya subvariant ihwanye na 90% by'indwara zose ziherutse kuba muri Danimarike. Danemark yagaragaye vuba aha mu mubare w'abantu bapfuye bazize kwandura COVID-19.

Ibyavuye muri kaminuza ya Tokiyo mu Buyapani n'ibibera muri Danimarike byamenyesheje impuguke mpuzamahanga.

Epidemiologue Dr. Eric Feigl-Ding yerekeje kuri Twitter ahamagarira ko OMS (Umuryango w’ubuzima ku isi) itangaza ko ubwoko bushya bwa Omicron BA.2 butera impungenge.

Maria Van Kerkhove, umuyobozi wa tekinike wa OMS kuri coronavirus nshya, na we yavuze ko BA.2 isanzwe ari variant nshya ya Omicron.

Abashakashatsi bavuze.

"Nubwo BA.2 ifatwa nk'imiterere mishya ya mutant ya Omicron, uko genome ikurikirana itandukanye cyane na BA.1, byerekana ko BA.2 ifite imiterere ya virusi itandukanye na BA.1."

BA.1 na BA.2 bifite ihinduka ryinshi, cyane cyane mubice byingenzi bya poroteyine ya virusi. Jeremy Luban, inzobere mu bijyanye na virusi mu ishuri ry’ubuvuzi rya kaminuza ya Massachusetts, yavuze ko BA.2 ifite ihinduka ry’imihindagurikire mishya nta muntu wigeze yipimisha.

Mads Albertsen, umuhanga mu binyabuzima muri kaminuza ya Aalborg muri Danimarike, yavuze ko ubwiyongere bukabije bwa BA.2 mu bihugu byinshi byerekana ko bufite inyungu zo gukura kurenza izindi mpinduka, harimo n’ubundi bwoko butandukanye bwa Omicron, nk’ibintu bitamenyekana cyane bizwi nka BA. 3.

Ubushakashatsi bwakozwe ku miryango irenga 8000 yo muri Danemarke yanduye omicron yerekana ko kwiyongera kwa BA.2 kwandura biterwa nimpamvu zitandukanye. Abashakashatsi barimo Troels Lillebaek, inzobere mu byorezo akaba na perezida wa komite ya Danemark ishinzwe gusuzuma ingaruka za COVID-19 zitandukanye, basanze abantu badakingiwe, inkingo ebyiri ndetse n’inkingo zatewe na booster bose bashobora kuba banduye BA.2 kurusha BA.1. kwandura.

Ariko Lillebaek yavuze ko BA.2 ishobora guteza ikibazo gikomeye aho umubare w’inkingo uri muke. Inyungu yo gukura yiyi variant kurenza BA.1 bivuze ko ishobora kongera igihe cyo kwandura omicron, bityo bikongerera amahirwe yo kwandura abasaza nabandi bantu bafite ibyago byinshi byindwara zikomeye.

Ariko hari ahantu heza: antibodies mumaraso yabantu baherutse kwandura virusi ya omicron nayo isa nkaho itanga uburinzi kuri BA.2, cyane cyane niba nabo barakingiwe.

Umuhanga mu bumenyi bwa virusi ya kaminuza ya kaminuza ya Washington, Deborah Fuller, avuga ko ibi bitera ingingo y'ingenzi, ko mu gihe BA.2 isa nkaho yanduye kandi itera indwara kurusha Omicron, idashobora kurangira itera umuvuduko ukabije w’ubwandu bwa COVID-19.

Yavuze ko virusi ari ngombwa, ariko natwe turi nk'abashobora kuyakira. Turacyari mu marushanwa yo kurwanya virusi, kandi ntabwo igihe kirageze ngo abaturage bakureho amategeko ya mask.
