Ib qho tshiab thiab muaj kev sib kis ntau dua thiab txaus ntshai ntawm Omicron, tam sim no lub npe hu ua Omicron BA.2 subtype variant, tau tshwm sim uas tseem ceeb tab sis tsis tshua tham txog qhov xwm txheej hauv Ukraine. (Editor's note: Raws li WHO, Omicron strain suav nrog b.1.1.529 spectrum thiab nws cov xeeb leej xeeb ntxwv ba.1, ba.1.1, ba.2 thiab ba.3. ba.1 tseem suav nrog feem ntau ntawm cov kab mob, tab sis cov kab mob ba.2 tau nce ntxiv.)
BUPA ntseeg hais tias qhov kev hloov pauv ntxiv hauv kev lag luam thoob ntiaj teb ob peb hnub dhau los no yog vim muaj qhov tsis zoo ntawm qhov xwm txheej hauv Ukraine, thiab lwm qhov laj thawj yog qhov hloov pauv tshiab ntawm Omicron, qhov hloov pauv tshiab ntawm tus kab mob uas lub koom haum ntseeg tias muaj kev pheej hmoo thiab nws cov macro cuam tshuam rau kev lag luam thoob ntiaj teb tej zaum yuav tseem ceeb tshaj qhov xwm txheej hauv Ukraine.
Raws li qhov kev tshawb pom tshiab tshaj plaws los ntawm University of Tokyo hauv Nyij Pooj, BA.2 subtype variant tsis tsuas yog kis tau sai dua piv rau tam sim no uas muaj COVID-19, Omicron BA.1, tab sis kuj tseem tuaj yeem ua rau mob hnyav thiab zoo li tuaj yeem cuam tshuam. qee yam riam phom tseem ceeb uas peb muaj tawm tsam COVID-19.
Cov kws tshawb fawb tau kis tus kab mob BA.2 thiab BA.1 hom kab mob sib kis, thiab pom tias cov neeg kis tus kab mob BA.2 tau mob thiab ua rau mob ntsws hnyav dua. Cov kws tshawb fawb pom tias BA.2 tseem tuaj yeem hla qee cov tshuaj tiv thaiv uas tsim los ntawm cov tshuaj tiv thaiv thiab tiv thaiv qee cov tshuaj kho.
Cov kws tshawb fawb ntawm qhov kev sim tau hais tias, "Kev sim ntsuas nruab nrab qhia tias kev txhaj tshuaj tiv thaiv kab mob tsis ua haujlwm zoo rau BA.2 raws li nws tawm tsam BA.1."
Cov kab mob BA.2 txawv ntawm tus kab mob no tau raug tshaj tawm nyob rau ntau lub tebchaws, thiab Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb tau kwv yees tias BA.2 yog kwv yees li 30 feem pua tau kis tus kabmob BA.1 tam sim no, uas tau pom nyob rau hauv 74 lub tebchaws thiab 47 lub xeev Asmeskas.
Tus kab mob subvarian no suav txog 90% ntawm tag nrho cov mob tshiab tsis ntev los no hauv Denmark. Lub tebchaws Denmark tau pom qhov rov qab los tsis ntev los no ntawm cov neeg mob uas tau tuag vim yog kis tus kabmob COVID-19.
Cov kev tshawb pom los ntawm University of Tokyo hauv Nyij Pooj thiab qhov tshwm sim hauv Denmark tau ceeb toom rau qee tus kws tshaj lij thoob ntiaj teb.
Tus kws kho mob kis kab mob Dr. Eric Feigl-Ding tau coj mus rau Twitter hu tawm qhov xav tau rau WHO (Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb) tshaj tawm qhov hloov pauv tshiab ntawm Omicron BA.2 ua rau muaj kev txhawj xeeb.
Maria Van Kerkhove, WHO tus kws tshaj lij rau tus kabmob tshiab, kuj tau hais tias BA.2 yog qhov hloov pauv tshiab ntawm Omicron.
Cov kws tshawb fawb tau hais.
"Txawm hais tias BA.2 raug suav hais tias yog qhov hloov pauv tshiab ntawm Omicron, nws cov kab ke genome txawv ntawm BA.1, qhia tias BA.2 muaj qhov sib txawv ntawm cov kab mob sib txawv dua li BA.1."
BA.1 thiab BA.2 muaj ntau qhov kev hloov pauv, tshwj xeeb tshaj yog nyob rau hauv qhov tseem ceeb ntawm cov kab mob stinger protein. Jeremy Luban, tus kws kho mob virologist ntawm University of Massachusetts Medical School, tau hais tias BA.2 muaj tag nrho cov kev hloov pauv tshiab uas tsis muaj leej twg tau sim.
Mads Albertsen, kws tshaj lij bioinformatician ntawm Aalborg University hauv Denmark, tau hais tias kev sib kis tsis tu ncua ntawm BA.2 hauv ntau lub tebchaws qhia tias nws muaj kev loj hlob zoo dua lwm cov kev hloov pauv, suav nrog lwm hom kev hloov pauv ntawm Omicron, xws li cov spectrum tsis tshua muaj npe hu ua BA. 3.
Kev tshawb fawb ntawm ntau dua 8,000 Danish tsev neeg muaj tus kab mob omicron qhia tias qhov nce ntawm tus kab mob BA.2 yog vim muaj ntau yam. Cov kws tshawb fawb, suav nrog Troels Lillebaek, tus kws kho mob kis mob thiab tus thawj coj ntawm Pawg Neeg Saib Xyuas Kev Nyab Xeeb Kev Nyab Xeeb ntawm COVID-19 Qhov txawv, pom tias cov neeg tsis tau txhaj tshuaj tiv thaiv ob zaug thiab tshuaj tiv thaiv kab mob yog txhua tus muaj feem kis tus kabmob BA.2 dua li BA.1. kab mob.
Tab sis Lillebaek tau hais tias BA.2 tuaj yeem ua rau muaj kev sib tw ntau dua qhov twg cov tshuaj tiv thaiv tsawg. Qhov kev loj hlob zoo ntawm qhov sib txawv no dhau BA.1 txhais tau tias nws tuaj yeem ua kom ntev lub ncov ntawm tus kab mob omicron, yog li ua rau muaj feem kis kab mob hauv cov neeg laus thiab lwm tus neeg uas muaj kev pheej hmoo siab rau cov kab mob loj.
Tab sis muaj qhov ci ntsa iab: cov tshuaj tiv thaiv kab mob hauv cov ntshav ntawm cov neeg uas nyuam qhuav kis tus kab mob omicron kuj tshwm sim muaj qee qhov kev tiv thaiv BA.2, tshwj xeeb tshaj yog tias lawv tau txhaj tshuaj tiv thaiv.
Qhov no tsa lub ntsiab lus tseem ceeb, hais tias University of Washington School of Medicine virologist Deborah Fuller, tias thaum BA.2 zoo nkaus li kis tau thiab muaj kab mob ntau dua li Omicron, nws yuav tsis xaus rau qhov ua rau muaj kev puas tsuaj ntau ntawm cov kab mob COVID-19.
Tus kab mob yog qhov tseem ceeb, nws hais tias, tab sis peb kuj yog nws tus tswv muaj peev xwm. Peb tseem nyob hauv kev sib tw tawm tsam tus kabmob, thiab nws tsis yog lub sijhawm rau cov zej zog los txhawb nqa txoj cai npog ntsej muag.
