Ngakhale anthu ambiri akhala akuganizira kwambiri za mitundu yosiyanasiyana ya Delta, ofufuza tsopano akunena kuti mtundu wa C.1.2 wa COVID-19 nawonso uyenera kuunikidwa.

Kafukufuku woyambirira kusindikizidwa medRxiv sabata yatha (yomwe sinawunikidwenso ndi anzawo) idafotokoza mwatsatanetsatane momwe kusinthika kwa C.1.2 kudasinthira kuchokera ku C.1, zovuta zomwe zidayambitsa matenda oyamba a SARS-CoV-2 (kachilombo kamene kamayambitsa COVID-19) ku South Africa. Mavuto a C.1 adapezeka komaliza ku South Africa mu Januware chaka chino, malinga ndi malipoti, vuto la C.1.2 lidawonekera mdziko muno mu Meyi.

Kupitilira South Africa, komabe, ofufuza akuti kusiyana kwa C.1.2 kwapezeka m'maiko ena kuzungulira Africa, Europe, ndi Asia, koma osati U.S.

Ngakhale pali mafunso ambiri pazomwe zikubwera za C.1.2, Nazi zomwe muyenera kudziwa, komanso zomwe azaumoyo akunena.

Kodi C.1.2 COVID-19 ndiyotani?

C.1.2 ndi mtundu womwe udadziwika panthawi yachitatu ya matenda a COVID-19 ku South Africa kuyambira mu Meyi chaka chino, malinga ndi medRxiv lipoti.

Kuphatikiza apo, ofufuza apeza kuti mtundu wa C.1.2 uli ndi "zosinthika zambiri" zomwe zadziwika mu "mitundu inayi yodetsa nkhawa" ya COVID-19: Alpha, Beta, Delta, ndi Gamma. Kodi izi zikutanthauza chiyani, ndendende? Poyambira, Centers for Disease Control and Prevention imazindikira mitundu ya COVID-19 ngati ma VOC kutengera umboni wotsimikizira kuwonjezeka kwa kufalikira, matenda owopsa (opitilira kuchipatala kapena kufa), ndikuchepetsa mphamvu yothandizira.

Ndipo ngakhale CDC sinaphatikizepo C.1.2 pamndandanda wake wa VOC, ofufuza a mdRxiv lipoti losiyanasiyana "lili ndi zolowa m'malo zingapo ... ndi kufufutidwa ... mkati mwa protein yolimba." Ndipo, ICYDK, puloteni ya spike ili kunja kwa kachilomboka ndipo imatha kumamatira kuma cell anu, zomwe zimayambitsa COVID-19. Malowa m'malo ndi kuchotsedwa kwamapuloteni a spike "awonedwa mu ma VOC ena ndipo amalumikizidwa ndikuwonjezereka kosunthika ndikuchepetsa mphamvu yakusalowerera ndale," malinga ndi kafukufukuyu.

Kodi Anthu Ayenera Kukhudzidwa Motani ndi Kusiyana kwa C.1.2?

Sizikudziwika bwinobwino pakadali pano. Ngakhale ofufuza amene analemba mdRxiv lipoti silikutsimikiza. "Ntchito yamtsogolo ikufuna kudziwa momwe kusinthaku kungakhudzire, komwe kungaphatikizepo kuthawa kwa ma antibody, ndikufufuza ngati kuphatikiza kwawo kumapereka mwayi wolimbitsa thupi kuposa mtundu wa Delta," atero ofufuzawo. Kutanthauza, ntchito yambiri ikufunika kuti mupeze momwe zosinthazi zingakhalire zoipa komanso ngati zingapose Delta yomwe ili kale ndi mavuto.

Maria Van Kerkhove, Ph.D., mtsogoleri wa World Health Organisation's COVID-19, adapita ku Twitter Lolemba ndipo adati, "Pakadali pano, C.1.2 sikuwoneka kuti ikuyenda, koma tikufunika kutsatizana kwambiri. kuti ichitidwe & kugawidwa padziko lonse lapansi," adawonjezera Lolemba, "Delta ikuwoneka yopambana pamatsatidwe omwe alipo." Mwanjira ina, malinga ndi Van Kerkhove, kusiyanasiyana kwa Delta kumakhalabe kotsogola potengera zomwe zapezeka mpaka Ogasiti 2021.

Kuphatikiza apo, akatswiri a matenda opatsirana sakuwoneka kuti ali ndi mantha kwambiri pakadali pano. "Pali zochitika pafupifupi 100 zomwe zanenedwa padziko lonse lapansi ndipo sizikuwoneka kuti zikuwonjezeka chifukwa Delta ikulamulira mitundu ina," atero Amesh A. Adalja, MD, katswiri wodziwa za matenda opatsirana komanso katswiri wamaphunziro ku Johns Hopkins Center for Health Security.

"Pakadali pano, ichi sichinthu chachikulu chodetsa nkhawa," akuwonjezera William Schaffner, MD, katswiri wa matenda opatsirana komanso pulofesa ku Vanderbilt University School of Medicine. "Tikamayang'ana kwambiri, momwe timapangira kwambiri chibadwa, zochulukirapo zidzawonekera. Ena mwa iwo adzafalikira ndipo funso nlakuti, 'Kodi atenga nthunzi?'"

Dr. Schaffner akunenanso kuti kusiyana kwa Lambda, mwachitsanzo, "kwakhala kunja kwa kanthawi, koma sikunatenge nthunzi." Izi zikunenedwa, akuwona kuti sizikudziwika ngati C.1.2 itsatira njira yofananira. "Akufalikira pang'ono koma zina mwazosiyanasiyana zidzafalikira pang'ono osachita zina zambiri," akutero Dr. Schaffner.

Dr. Adalja akunena kuti palibe zambiri zoti zichitike ndi C.1.2 pakadali pano. "Pakadali pano, palibe chidziwitso chokwanira kuti athe kuwunika momwe tsogolo lawo lidzakhalire," akutero. "Komabe, kusiyana kwa Delta, chifukwa cha kulimba kwake kumapangitsa kuti zikhale zovuta kuti kusiyana kwina kupezeke."

Momwe Mungadzitetezere Kokha ku C.1.2 Zosiyanasiyana

Zikafika pamitundu yosiyanasiyana yodandaula nayo, C.1.2 sikuwoneka ngati imodzi mwa izo pakadali pano. M'malo mwake, sichinapezeke ku US pano, malinga ndi lipoti lomwe latchulidwalo.

Komabe, Dr. Schaffner akuti mutha kudziteteza ku C.1.2 ndi mitundu ina mwa kulandira katemera wa COVID-19. Akukulimbikitsanso kuti muwombere chilimbikitso pakadutsa miyezi isanu ndi itatu kuchokera pomwe mwalandira katemera wachiwiri wa mRNA (mwina Pfizer-BioNTech kapena Moderna), malinga ndi malingaliro a CDC. (FYI, chowombera chowonjezera cha katemera wa mlingo umodzi wa Johnson & Johnson sichinaloledwebe.)

Kupitiliza kuvala chigoba mukakhala m'nyumba m'malo omwe kufalikira kwa kachilomboka ndikwambiri ndi njira yothandiza yochepetsera chiopsezo chotenga matenda a COVID-19. “Izi ndi zinthu zomwe tiyenera kuchita kuti tikhale otetezedwa,” akutero Dr. Schaffner. "Mukachita zingapo mwa izo, mumatetezedwa kwambiri."

Zomwe zili munkhaniyi ndizolondola monga nthawi yolemba. Pomwe zosintha za coronavirus COVID-19 zikupitilizabe kusintha, ndizotheka kuti zina ndi zina zomwe zanenedwa m'nkhaniyi zasintha kuyambira pomwe zidasindikizidwa koyamba. Tikukulimbikitsani kuti mumayang'anitsitsa pafupipafupi ndi zinthu monga CDC, WHO, ndi dipatimenti yazaumoyo yakwanuko kuti mumve zambiri zamtunduwu komanso malingaliro awo.
