Ngelixa abantu abaninzi bejolise kwi-laser kukwahluka okuchaphazeleka kakhulu kwe-Delta, abaphandi ngoku bathi u-C.1.2 okwahlukileyo kwe-COVID-19 kunokuba kufanelekile ukuhoywa nawo.

Isifundo sokuprinta kwangaphambili esithunyelwe ngomhla medRxiv kwiveki ephelileyo (engekaphononongwa ngoontanga) ichaze indlela umahluko we-C.1.2 owavela ngayo ukusuka ku-C.1, ubunzima obusemva kosulelo lokuqala lwe-SARS-CoV-2 (intsholongwane ebangela i-COVID-19) eMzantsi Afrika. .I-C.1 strain igqityelwe ukubhaqwa eMzantsi Afrika kweyoMqungu kulo nyaka, ngokwengxelo, i-C.1.2 strain ibonakala kweli lizwe ngoMeyi.

Ngaphaya koMzantsi Afrika, nangona kunjalo, abaphandi bathi ukwahluka kweC.1.2 kufunyenwe kwamanye amazwe ajikeleze iAfrika, iYurophu, neAsia, kodwa hayi iU.S.

Nangona kusekho imibuzo emininzi ngolu hlobo luvelayo lwe-C.1.2, nantsi into ekufuneka uyazi, kwaye amagosa ezempilo athini.

Yintoni i-C.1.2 COVID-19 eyahlukileyo?

C.1.2 ngumahluko okwafunyanwa ngexesha lomsinga wesithathu wosulelo lwe-COVID-19 eMzantsi Afrika ukuqala ngoMeyi walo nyaka, ngokwe I-medRxiv ingxelo.

Ukongeza, abaphandi bafumanise ukuba i-C.1.2 eyahlukileyo iqulethe "izinto ezininzi eziguqulweyo" ezichongiweyo kwii-COVID-19 ezine "ezahlukeneyo zenkxalabo": Alfa, Beta, Delta, kunye neGamma. Kuthetha ukuthini oku, kanye? Kwabaqalayo, amaZiko oLawulo lweZifo noThintelo athathela ingqalelo ukwahluka kwe-COVID-19 njengee-VOC ngokusekwe kubungqina obuxhasa ukwanda kokuhanjiswa, isifo esibi kakhulu (ukuphakama esibhedlele okanye ukusweleka), kunye nokunciphisa ukusebenza konyango.

Kwaye ngelixa i-CDC ingekongezi i-C.1.2 eyahlukileyo kuluhlu lwayo lwe-VOC, abaphandi abavela I-medRxiv ingxelo yenqaku okwahlukileyo "inezinto ezininzi endaweni yazo ... kunye nokucinywa ... kwiprotein yespiki." Kwaye, ICYDK, iprotein ye-spike ingaphandle kwentsholongwane kwaye inokuncamathela kwiiseli zakho, ngaloo ndlela ibangela i-COVID-19. Ukufakwa endaweni okuninzi kunye nokucinywa kwiprotein ye-spike "kuye kwabonwa kwezinye ii-VOCs kwaye kunxulunyaniswa nokwanda kokuhambisa kunye nokunciphisa ubuntununtunu bokuthambeka," ngokophando.

Kufuneka Bakhathazeke Njani Abantu Ngalo C.1.2 Umahluko?

Akucaci ngoku kweli nqanaba. Nditsho nabaphandi ababhala i medRxiv ingxelo ayiqinisekanga. "Umsebenzi wexesha elizayo ujolise ekuqinisekiseni ifuthe elisebenzayo kolu tshintsho, olunokuthi lubandakanye ukubaleka kwe-antibody, kunye nokuphanda ukuba indibaniselwano yabo inika inzuzo yokuphindaphinda ukomelela ngaphezulu kokwahluka kweDelta," batsho abaphandi. Intsingiselo, umsebenzi omninzi uyafuneka ukufumana kanye ukuba lo mahluko unokuba mbi kangakanani kwaye ukuba unokugqitha iDelta esele iyingxaki. (Into omawuyenze ukuba ucinga ukuba une-COVID-19)

UMaria Van Kerkhove, Ph.D., okhokele i-COVID-19 ye-World Health Organisation, uthathe u-Twitter ngoMvulo kwaye wathi, "Ngeli xesha, u-C.1.2 akabonakali ngathi uphezulu, kodwa sifuna ukulandelelana ngakumbi. uzakwenziwa kwaye kwabelwane ngawo kwihlabathi liphela, "Wongeze uMvulo," I-Delta ibonakala ibalasele kulandelelwano olukhoyo. " Ngamanye amagama, ngokukaVan Kerkhove, umahluko weDelta uhlala ubalasele ngokusekwe kulandelelwano olukhoyo ngo-Agasti 2021.

Ngapha koko, iingcali zezifo ezosulelayo zibonakala zingoyiki ngoku. "Kukho malunga ne-100 yokulandelelana echazwe kwihlabathi jikelele kwaye akubonakali ngathi iyanda njengoko iDelta ilawula ezinye izinto," utshilo u-Amesh A. Adalja, MD, ingcali yesifo esosulelayo kunye nomphengululi omkhulu kwiziko i-Johns Hopkins Centre loKhuseleko lwezeMpilo.

"Okwangoku, oku akusona sizathu esikhulu sokukhathazeka," wongezelela uWilliam Schaffner, M.D., ingcali yezifo ezosulelayo kunye noprofesa kwi-Vanderbilt University School of Medicine. "Okukhona sijonga, kokukhona sisenza ngokulandelelana kwemfuza, kokukhona oku kuya kubonakala. Ezinye zazo ziya kusasazeka kwaye umbuzo ngulo, 'Ngaba baya kuthatha umphunga?'"

UGqr Schaffner ubonisa kwakhona ukuba ukwahluka kweLambda, umzekelo, "kuye kwaphuma ixesha elide, kodwa akuzange kuthathe umphunga." Oko kuthethiweyo, uqaphela ukuba akucaci ukuba i-C.1.2 iya kulandela indlela efanayo. Isasaza kancinci kodwa ezinye zezi zinto zahlukileyo ziya kusasazeka kancinci kwaye zingenzi enye into, utshilo uGqirha Schaffner.

Ugqirha Adalja uqaphele ukuba akukho nto ingako yokuqhubeka no-C.1.2 ngoku. “Okwangoku, akukho lwazi lwaneleyo lokukwazi ukuvavanya ukuba ikamva liza kuba yintoni na,” utshilo. "Nangona kunjalo, ukwahluka kweDelta, ngenxa yokuqina kwayo kwenza kube nzima kakhulu ukuba ezinye iiyantlukwano zifumane indawo."

Uzikhusela njani kuLuhlu lwe-C.1.2

Xa kufikwa kwizinto ezahlukileyo zokukhathazeka, C.1.2 kubonakala ngathi ayisiyiyo enye yazo ngalo mzuzu. Ngapha koko, ayikafunyanwa e-US okwangoku, ngokwengxelo ekhankanywe ngasentla.

Nangona kunjalo, uGqirha Schaffner uthi ungazikhusela kwi-C.1.2 nakwezinye izinto ngokugonya ngokupheleleyo i-COVID-19. Ucebisa ngokufumana i-booster shot emva kweenyanga ezisibhozo ukusukela kwidosi yakho yesibini ye-mRNA vaccine (nokuba yiPfizer-BioNTech okanye iModerna), ngokweengcebiso zeCDC. (I-FYI, i-booster shot yedosi enye yokugonya i-Johnson & Johnson ayikagunyaziswa.)

Ngokuqhubeka nokunxiba imaski xa ungaphakathi ezindlini kwiindawo apho ukusasazeka kwale ntsholongwane kuphezulu ikwayindlela eluncedo yokwehlisa umngcipheko wakho wokufumana naluphi na uhlobo lwe-COVID-19. "Ezi zizinto ekufuneka sizenzile ukuze sihlale sikhuselekile," utshilo uGqirha Schaffner. "Ukuba wenza ezininzi zazo, ukhuseleke ngakumbi."

Ulwazi kweli bali luchanekile ngexesha lokushicilelwa. Njengoko uhlaziyo malunga ne-coronavirus ye-COVID-19 luqhubeka nokuvela, kunokwenzeka ukuba ezinye iinkcukacha kunye nezindululo kweli bali zitshintshile ukusukela ekupapashweni kwayo. Siyakukhuthaza ukuba ujonge rhoqo ngezixhobo ezinjenge-CDC, i-WHO, kunye nesebe lezempilo likarhulumente kwindawo yakho yokufumana olona lwazi lwanamhlanje kunye neengcebiso.
