1. Kupezeka ndi kufalikira kwa mitundu yosinthika ya Omi Keron Pa Novembara 9, 2021, South Africa idapeza mtundu wa B.1.1.529 wa kachilombo ka corona kwanthawi yoyamba. M'milungu iwiri yokha, mtundu wa mutant unakhala vuto lalikulu kwambiri la matenda atsopano a koronavirus ku Gauteng Province, South Africa, ndipo kukula kwake kunali kofulumira. Pa Novembara 26, WHO idafotokoza kuti ndi yachisanu "yosiyana yodetsa nkhawa" (VOC), yomwe idatcha chilembo chachi Greek Omicron (Omicron). Pofika pa November 28, South Africa, Israel, Belgium, Italy, United Kingdom, Austria, ndi Hong Kong, China, akhala akuyang'anira momwe mtunduwo umasinthira. Kuyika kwamtunduwu sikunapezeke m'zigawo zina ndi mizinda m'dziko langa. Omi Keron mutant adapezeka koyamba ndikufotokozedwa ku South Africa, koma sizitanthauza kuti kachilomboka kanayamba ku South Africa. Sikuti malo amene mutant anapezeka si malo kwenikweni.
2. Zifukwa zotheka kuonekera kwa Omi Keron mutants Malinga ndi zomwe panopa ndi latsopano koronavirus nkhokwe Nawonso achichepere GISAID, chiwerengero cha masinthidwe malo a latsopano korona virus Omi Keron mutant kupsyinjika ndi kwambiri kuposa ma virus onse atsopano korona. mitundu yosinthika yomwe yakhala ikuzungulira zaka ziwiri zapitazi, makamaka pakusintha kwa protein spike (Spike). . Zikuganiziridwa kuti zifukwa za kutuluka kwake kungakhale zinthu zitatu izi: (1) Wodwala immunodeficiency atatenga kachilombo katsopano ka coronavirus, adakumana ndi nthawi yayitali yosinthika m'thupi kuti adziunjikire kuchuluka kwa masinthidwe, omwe zimafalitsidwa mwangozi; (2) matenda enaake a gulu la nyama New coronavirus, kachilomboka kamakhala ndi kusintha kosinthika pakufalikira kwa nyama, ndipo masinthidwe amasinthidwe ndi apamwamba kuposa a anthu, kenako amakhuthukira mwa anthu; (3) Mtundu wosinthikawu wapitilira kufalikira kwa nthawi yayitali m'maiko kapena madera omwe kuwunika kwa masinthidwe amtundu watsopano wa coronavirus kukucheperachepera. , Chifukwa chosakwanira kuwunika kuwunika, ma virus am'badwo wapakatikati a chisinthiko chake sakanatha kudziwika munthawi yake.
3. Kutha kufala kwa Omi Keron mutant strain Pakali pano, palibe kafukufuku watsatanetsatane wa kufala, kudwala, komanso mphamvu yopulumukira ya Omi Keron mutants padziko lapansi. Komabe, mtundu wa Omi Keron ulinso ndi malo ofunikira amino acid osinthika mumitundu inayi yoyamba ya VOC Alpha, Beta, Gamma ndi Delta spike proteins, kuphatikiza ma cell receptors owonjezera. Masamba osinthika a somatic kuyanjana komanso kuthekera kobwereza ma virus. Kuwunika kwa Epidemiological and laboratory monitoring data kukuwonetsa kuti kuchuluka kwa mitundu ya Omi Keron ku South Africa kwakwera kwambiri, ndipo kwalowa m'malo mwa Delta (Delta). Mphamvu yopatsirana iyenera kuyang'aniridwa ndi kuphunziridwanso.
4. Mphamvu ya mitundu yosiyanasiyana ya Omi Keron pa katemera ndi mankhwala a antibody Kafukufuku wasonyeza kuti kukhalapo kwa masinthidwe a K417N, E484A, kapena N501Y mu S protein ya coronavirus yatsopano kumasonyeza kuti chitetezo cha mthupi chimatha kuthawa; pomwe Omi Keron mutant alinso ndi kusintha katatu kwa "K417N + E484A+N501Y"; Kuphatikiza apo, Omi Keron mutant palinso masinthidwe ena ambiri omwe angachepetse ntchito yoletsa ma antibodies ena a monoclonal. Kukula kwa masinthidwe kumatha kuchepetsa mphamvu zoteteza za mankhwala ena a antibody motsutsana ndi Omi Keron mutants, komanso kuthekera kwa katemera omwe alipo kuti athawe chitetezo chokwanira kumafuna kuwunika ndi kufufuza kwina.
5. Kodi kusinthika kwa Omi Keron kumakhudza zozindikiritsa za nucleic acid zomwe zikugwiritsidwa ntchito pano m'dziko langa? Kuwunika kwa ma genome a mtundu wa Omi Keron mutant kunawonetsa kuti malo ake osinthika samakhudza kukhudzika ndi kutsimikizika kwa ma nucleic acid omwe amazindikira ma nucleic acid m'dziko langa. Malo osinthika a Omi Keron mutant strain amakhazikika kwambiri m'chigawo chosinthika kwambiri cha jini ya S protein, ndipo sapezeka mu nucleic acid discovery reagent primers ndi madera omwe akuwunikira omwe adasindikizidwa mu kope lachisanu ndi chitatu la "New Coronavirus Pneumonia" ya dziko langa. Prevention and Control Program” (China The ORF1ab gene ndi N gene yotulutsidwa ndi Centers for Disease Control and Prevention to the world). Komabe, deta yochokera ku ma laboratories angapo ku South Africa imasonyeza kuti ma nucleic acid reagents omwe amazindikira jini ya S sangathe kuzindikira bwino jini ya S ya mtundu wa Omi Keron.
6. Njira zomwe mayiko ndi zigawo zomwe zikuyenera kutengedwa Poona momwe miliri ya Omi Keron imasinthira ku South Africa, mayiko ndi zigawo zambiri, kuphatikiza United States, United Kingdom, European Union, Russia, Israel, Taiwan ya dziko langa ndi Hong Kong, aletsa kulowa kwa alendo ochokera kumwera kwa Africa.
7. Mayankho a dziko langa Njira yopewera ndi kuwongolera dziko lathu la "chitetezo chakunja, chitetezo chamkati motsutsana ndi kuyambiranso" ikugwirabe ntchito motsutsana ndi Omi Keron mutant. Institute of Viral Diseases of the Chinese Center for Disease Control and Prevention yakhazikitsa njira yodziwira ma nucleic acid ya mtundu wa Omi Keron mutant, ndipo ikupitilizabe kuyang'anira ma virus pamilandu yomwe ingabwere kuchokera kunja. Njira zomwe tatchulazi zithandizira kuzindikira munthawi yake zosinthika za Omi Keron zomwe zitha kutumizidwa kudziko langa.
8. Malingaliro a WHO okhudzana ndi zovuta za Omi Keron mutant The WHO imalimbikitsa kuti mayiko alimbikitse kuyang'anira, kupereka malipoti ndi kafukufuku wa coronavirus yatsopano, ndikuchitapo kanthu paumoyo wa anthu kuti aletse kufalikira kwa kachilomboka; Njira zopewera matenda zomwe zimalimbikitsidwa kwa anthu ndi monga kukhala ndi mtunda wa mita imodzi pamalo opezeka anthu ambiri, kuvala masks, kutsegula mawindo olowera mpweya, komanso kusunga Sambani m'manja, kutsokomola kapena kuyetsemula m'zigongono kapena minofu, kulandira katemera, ndi zina zambiri. pewani kupita kumalo opanda mpweya wabwino kapena malo odzaza anthu. Poyerekeza ndi mitundu ina ya VOC, sizikudziwikabe ngati mtundu wa Omi Keron uli ndi kufalikira kwamphamvu, mphamvu ya pathogenicity komanso mphamvu yopulumukira ya chitetezo chamthupi. Kafukufuku woyenerera adzapeza zotsatira zoyambirira m'masabata angapo otsatira. Koma zomwe zimadziwika pakadali pano ndikuti mitundu yonse yosinthika imatha kuyambitsa matenda kapena kufa kwambiri, chifukwa chake kupewa kufalikira kwa kachilomboka ndiye chinsinsi nthawi zonse, ndipo katemera watsopano wa korona akadali wothandiza kuchepetsa matenda akulu ndi imfa.
9. Poyang'anizana ndi mtundu watsopano wa coronavirus watsopano Omi Keron, kodi anthu ayenera kuyang'ana chiyani pa ntchito yawo ya tsiku ndi tsiku ndi ntchito? (1) Kuvala chigoba akadali njira yabwino yoletsera kufalikira kwa kachilomboka, komanso kumagwiritsidwa ntchito ku mitundu ina ya Omi Keron. Ngakhale njira yonse ya katemera ndi katemera wa chilimbikitso itatha, ndikofunikira kuvala chigoba m'malo opezeka anthu ambiri, mayendedwe apagulu ndi malo ena. Komanso, sambani m'manja pafupipafupi ndi ventilate chipinda. (2) Chitani ntchito yabwino yoyang'anira thanzi lanu. Ngati pali zizindikiro za chibayo chatsopano chapamtima, monga kutentha thupi, chifuwa, kupuma movutikira ndi zizindikiro zina, yang'anani kutentha kwa thupi mwachangu ndikuyambapo kukaonana ndi dokotala. (3) Chepetsani kulowa ndi kutuluka kosafunikira. M'masiku ochepa chabe, mayiko ndi zigawo zambiri zalengeza motsatizana za kuitanitsa mitundu ya Omi Keron mutant. China ikuyang'anizananso ndi chiwopsezo chotengera mtundu wamtunduwu wamtunduwu, ndipo chidziwitso chapadziko lonse lapansi chokhudza mtundu wosinthikawu ndi chochepa. Chifukwa chake, kuyenda kumadera omwe ali pachiwopsezo chachikulu kuyenera kuchepetsedwa, ndipo chitetezo chamunthu paulendo chiyenera kulimbikitsidwa kuti achepetse mwayi wotenga matenda a Omi Keron mutant.
