Nooc cusub oo faafa oo khatar badan oo Omicron ah, oo hadda lagu magacaabo Omicron BA.2 nooc-hoosaadka, ayaa soo baxay kaas oo sidoo kale muhiim ah laakiin aan laga hadlin marka loo eego xaaladda Ukraine.(Xusuusin tifaftiraha: Sida laga soo xigtay WHO, nooca Omicron waxaa ka mid ah b.1.1.529 spectrum iyo farcankeeda ba.1, ba.1.1, ba.2 iyo ba.3. ba.1 weli waxay xisaabiyaan inta badan caabuqyada, laakiin ba.2 caabuq ayaa kor u kacaya.)
BUPA waxay aaminsan tahay in isbedbedelka dheeraadka ah ee suuqyada caalamiga ah dhowrkii maalmood ee la soo dhaafay ay sabab u tahay xaalada sii xumaanaysa ee Ukraine, sabab kale ayaa ah kala duwanaanshaha cusub ee Omicron, nooc cusub oo fayraska ah oo ay hay'addu aaminsan tahay inuu kor u kacayo khatarta saamaynta macro ee dhaqaalaha caalamiga ah waxaa laga yaabaa in xitaa ka sii muhiimsan tahay xaaladda Ukraine.
Marka loo eego natiijooyinkii ugu dambeeyay ee Jaamacadda Tokyo ee Japan, kala duwanaanshaha nooca-hoosaadka ee BA.2 kaliya kuma fido dhaqso marka la barbar dhigo kan hadda jira ee COVID-19, Omicron BA.1, laakiin wuxuu sidoo kale sababi karaa jirro daran wuxuuna u muuqdaa inuu awood u leeyahay inuu joojiyo. qaar ka mid ah hubka muhiimka ah ee aan u haysano ka hortagga COVID-19.
Cilmi-baadhayaashu waxay hamsters-ka ku qaadeen noocyada BA.2 iyo BA.1, siday u kala horreeyaan, waxayna ogaadeen in kuwa uu ku dhacay BA.2 ay ka sii xanuunsadeen oo ay soo gaareen dhaawac aad u daran.Cilmi-baadhayaashu waxay ogaadeen in BA.2 laga yaabo inay xitaa hareer marto qaar ka mid ah unugyada difaaca jirka ee uu soo saaray tallaalku oo ay u adkaysato daawooyinka daweynta qaarkood.
Cilmi-baarayaasha tijaabada ayaa yiri, "Tijaabooyin dhexdhexaadin ah ayaa soo jeedinaya in difaaca tallaalku uusan si fiican u shaqeynin BA.2 sida uu uga hortago BA.1."
Kiisaska fayraska kala duwan ee BA.2 ayaa laga soo sheegay wadamo badan, Ururka Caafimaadka Adduunka ayaa ku qiyaasay in BA.2 uu ka badan yahay boqolkiiba 30 marka loo eego BA.1 hadda, kaas oo laga helay 74 waddan iyo 47 gobol oo Maraykan ah.
Fayraskan kala duwan ayaa 90% ka ah dhammaan kiisaska cusub ee Danmark.Danmark waxay aragtay dhawaan dib u soo kabashada tirada kiisaska u dhintay caabuqa COVID-19.
Natiijooyinka ka soo baxay Jaamacadda Tokyo ee Japan iyo waxa ka dhacaya Denmark ayaa digniin u diray khubaro caalami ah.
Khabiir ku takhasusay cudurrada faafa Dr. Eric Feigl-Ding ayaa bartiisa Twitter-ka ku soo qoray baahida loo qabo in WHO (Ururka Caafimaadka Adduunka) ay ku dhawaaqdo kala duwanaanshaha cusub ee Omicron BA.2 sabab walaac leh.
Maria Van Kerkhove, oo ah hogaamiyaha farsamada ee WHO ee coronavirus-ka cusub, ayaa sidoo kale sheegtay in BA.2 ay horeyba u tahay nooc cusub oo Omicron ah.
Cilmi-baarayaashu waxay sheegeen.
"In kasta oo BA.2 loo tixgeliyo inay tahay nooc cusub oo mutant ah oo Omicron ah, isku xigxiga genome-ga ayaa aad uga duwan BA.1, taasoo soo jeedinaysa in BA.2 ay leedahay muuqaal fayras oo ka duwan BA.1."
BA.1 iyo BA.2 waxay leeyihiin daraasiin isbeddello ah, gaar ahaan qaybaha muhiimka ah ee borotiinka stinger-ka ee fayraska.Jeremy Luban, oo ku takhasusay cilmiga virologist kana tirsan Jaamacadda Massachusetts Medical School, ayaa sheegay in BA.2 ay leedahay tiro dhan oo isbedelo cusub ah oo aan cidina tijaabin.
Mads Albertsen, oo cilmi-nafsi yaqaan ah oo ka tirsan jaamacadda Aalborg ee Denmark, ayaa sheegay in faafitaanka joogtada ah ee BA.2 ee dalal dhowr ah ay soo jeedinayso inay faa'iido koritaan ka leedahay noocyada kale, oo ay ku jiraan noocyada kale ee noocyada kale ee Omicron, sida noocyada caanka ah ee yar ee loo yaqaan BA. 3.
Daraasad lagu sameeyay in ka badan 8,000 oo qoys Danish ah oo uu ku dhacay omicron ayaa soo jeedinaysa in kororka heerka caabuqa BA.2 ay sabab u tahay arrimo kala duwan.Cilmi-baarayaasha, oo ay ku jiraan Troels Lillebaek, oo ah khabiir ku takhasusay cudurrada faafa iyo guddoomiyaha guddiga Danishka ee qiimeynta khatarta ah ee COVID-19 Variants, waxay ogaadeen in aan la tallaalin, laba-tallaalan iyo kuwa xoojiya-tallaalka ah ay dhammaantood aad ugu dhowdahay in lagu qaado BA.2 marka loo eego BA.1 caabuq.
Laakin Lillebaek waxa uu sheegay in BA.2 ay keeni karto caqabad weyn halka heerarka talaalka ay hooseeyaan.Faa'iidada koritaanka ee kala duwanaanshahan BA.1 waxay la macno tahay inay sii dheerayn karto heerka ugu sarreeya ee caabuqa omicron, taas oo kordhinaysa fursadaha caabuqa ee waayeelka iyo dadka kale ee khatarta sare ugu jira cudurro halis ah.
Laakin waxaa jirta bar ifaya: unugyada difaaca jirka ee ku jira dhiiga dadka dhawaan qaaday fayraska omicron waxay sidoo kale u muuqdaan inay bixiyaan xoogaa ka hortag ah BA.2, gaar ahaan haddii iyagana la tallaalay.
Tani waxay kor u qaadaysaa qodob muhiim ah, ayay tidhi Jaamacadda Washington School of Medicine virologist Deborah Fuller, in iyadoo BA.2 ay u muuqato inay ka badan tahay caabuqa iyo cudur-sidaha marka loo eego Omicron, laga yaabo inaysan ku dhammaanayn inay keento mowjad aad u xun oo ah caabuqyada COVID-19.
Fayrasku waa muhiim, ayay tidhi, laakiin sidaas oo kale ayaanu nahay martigelintiisa.Waxaan wali ku jirnaa tartan ka dhan ah fayraska, lamana joogo waqtigii bulshooyinku ay qaadi lahaayeen sharciga maaskaro.
