Ngenkathi abantu abaningi begxile kwelaser kokuhlukile okuthelelana kakhulu kwe-Delta, abacwaningi manje bathi okuhlukile kwe-C.1.2 kwe-COVID-19 kungakuhle ukubhekelela nakho.

Isifundo sangaphambi kokuphrinta sithunyelwe ku- medRxiv ngesonto eledlule (lokho okungakabuyekezwa kontanga) kuningiliziwe ukuthi okuhlukile kwe-C.1.2 kwavela kanjani ku-C.1, ubunzima obabangelwa igagasi lokuqala lokutheleleka nge-SARS-CoV-2 (igciwane elibangela i-COVID-19) eNingizimu Afrika Uhlobo lwe-C.1 lwagcina ukutholakala eNingizimu Afrika ngoJanuwari walo nyaka, ngokusho kombiko, kwathi uhlobo luka-C.1.2 lwavela kuleli ngoMeyi.

Ngale kweNingizimu Afrika, nokho, abacwaningi bathi okuhlukile kwe-C.1.2 kutholakele kwamanye amazwe ase-Afrika, eYurophu, nase-Asia, kodwa hhayi e-U.S.

Nakuba kusenemibuzo eminingi mayelana nalokhu okuhlukile kwe-C.1.2, nakhu okudingeka ukwazi, nokuthi izikhulu zezempilo zithini.

Yini i-C.1.2 COVID-19 Variant?

C.1.2 okuhlukile okutholakale ngesikhathi somsakazo wesithathu wezifo ze-COVID-19 eNingizimu Afrika kusukela ngoMeyi walo nyaka, ngokusho kwe I-medRxiv bika.

Ngokwengeziwe, abacwaningi bathole ukuthi okuhlukile kwe-C.1.2 kuqukethe "ukuguqulwa okuningi" okukhonjwe kuzinto ezine ezikhathazayo ze-COVID-19: i-Alpha, iBeta, iDelta, neGamma. Kusho ukuthini lokhu, ngempela? Okokuqala, iZikhungo Zokulawulwa Nokuvimbelwa Kwezifo zibona okwahlukahluka kwe-COVID-19 njengama-VOCs asuselwe ebufakazini obusekela ukwanda kokuthwalwa, izifo ezinzima kakhulu (ukuphakama kokubhedlela noma ukufa), nokunciphisa ukusebenza kwezindlela zokwelapha.

Futhi nakuba i-CDC ingakangezi okuhlukile kwe-C.1.2 ohlwini lwayo lwe-VOC, abacwaningi abavela ku- I-medRxiv okuhlukile kombiko wenothi "uqukethe okushintshwayo okuningi ... nokususiwe ... ngaphakathi kweprotheni ye-spike." Futhi, i-ICYDK, iprotheni ye-spike itholakala ngaphandle kwegciwane futhi inganamathisela kumaseli akho, ngaleyo ndlela idale i-COVID-19. Ukushintshwa nokususwa okuningi ngaphakathi kweprotheni ye-spike "kuye kwabonwa kwamanye ama-VOC futhi kuhlotshaniswa nokwanda kokutholakala kokunye kanye nokunciphisa ukuzwela kwe-neutralization," ngokusho kocwaningo.

Kufanele Abantu Bakhathazeke Kangakanani Ngokuhluka kwe-C.1.2?

Akukacaci ngokuphelele okwamanje. Ngisho nabacwaningi ababhala i medRxiv umbiko awunasiqiniseko. "Umsebenzi wesikhathi esizayo uhlose ukunquma umthelela osebenzayo walokhu kuguqulwa, okungenzeka kufaka phakathi ukuphunyuka kwe-antibody, kanye nokuphenya ukuthi ukuhlanganiswa kwakho kunikeza inzuzo ephindaphindayo yokuqina kunokwehluka kwe-Delta," kusho abacwaningi. Okusho ukuthi, umsebenzi omningi uyadingeka ukuze uthole ukuthi lokhu kuhluka kungaba kubi kangakanani nokuthi kungadlula i-Delta esivele inenkinga.

UMaria Van Kerkhove, Ph.D., ohola i-World Health Organisation we-COVID-19, ubhekise kuTwitter ngoMsombuluko futhi wathi, "Ngalesi sikhathi, uC.1.2 akabonakali esesakazekile, kepha sidinga ukulandelana okwengeziwe ezokwenziwa nokwabelwana ngayo emhlabeni jikelele, "Wengeze ngoMsombuluko," iDelta ibukeka ibalulekile maqondana nokulandelana okutholakalayo. " Ngamanye amagama, ngokusho kukaVan Kerkhove, okuhlukile kweDelta kuhlala kubusa ngokususelwa ekulandelaneni okutholakalayo ngo-Agasti 2021.

Ngaphezu kwalokho, ochwepheshe bezifo ezithathelwanayo ababonakali bethuka ngokweqile manje. "Kunokulandelana okucishe kube yikhulu okubikwe emhlabeni jikelele futhi akubonakali kuyanda njengoba iDelta ibusa ezinye izinhlobo," kusho u-Amesh A. Adalja, MD, isazi sezifo ezithathelwanayo nesifundiswa esiphezulu eJohns Hopkins Center for Health Security.

"Okwamanje, lokhu akuyona imbangela enkulu yokukhathazeka," kunezela uWilliam Schaffner, M.D., uchwepheshe wezifo ezithathelwanayo kanye noprofesa eVanderbilt University School of Medicine. "Lapho sibheka kakhulu, kulapho silandelana kakhulu ngofuzo, kuzovela kakhulu lezi zinhlobonhlobo. Ezinye zazo zizosabalala futhi umbuzo uthi, 'Ingabe zizocosha umusi?'

UDkt Schaffner uphinde waveza ukuthi okuhlukile kweLambda, ngokwesibonelo, "bekukhona lapho isikhashana, kepha akukaze kuthathe umusi." Sekushiwo lokho, uphawula ukuthi akucaci ukuthi u-C.1.2 uzolandela yini indlela efanayo. "Isakazeka kancane kepha ezinye zalezi zinhlobonhlobo zizosabalala kancane futhi zingenzi okunye okuningi," kusho uDkt Schaffner.

UDkt. Adalja uphawula ukuthi akukho okuningi okuzoqhubeka no-C.1.2 njengamanje. "Okwamanje, alukho ulwazi olwanele olungakwazi ukuhlola ukuthi umkhondo walo wesikhathi esizayo uzoba yini," usho kanje. "Kodwa-ke, ukwahluka kweDelta, ngenxa yokuqina kwayo kwenza kube nzima kakhulu ukuthi okunye ukuhlukahluka kuzuze."

Ungazivikela Kanjani Ku-C.1.2 Variant

Uma kukhulunywa ngokuhlukahluka okufanele ukhathazeke ngakho, uC.1.2 kubonakala sengathi akayona enye yazo okwamanje. Eqinisweni, ayikatholakali e-U.S. Okwamanje, ngokusho kombiko osanda kuprintwa ngaphambili.

Nokho, uDkt. Schaffner uthi ungazivikela ku-C.1.2 nezinye izinhlobo ngokugonyelwa ngokugcwele i-COVID-19. Uphinde aphakamise ukuthi uthole i-booster shot uma sekuphele izinyanga eziyisishiyagalombili kusukela umthamo wakho wesibili womgomo we-mRNA (okungaba i-Pfizer-BioNTech noma i-Moderna), ngokusho kwezincomo ze-CDC. (FYI, i-booster shot yomuthi wokugomela umthamo owodwa ka-Johnson & Johnson awukakagunyazwa.)

Ngokuqhubeka nokugqoka imaskhi uma usendlini ezindaweni lapho ukusabalala kwegciwane kuphezulu futhi kuyindlela ewusizo yokwehlisa ingozi yokuthola noma yiluphi uhlobo lwe-COVID-19. "Lezi yizinto okufanele sizenze ukuze sihlale sivikelekile," kusho uDkt Schaffner. "Uma wenza eziningana zazo, uvikeleke nakakhulu."

Imininingwane ekule ndaba inembile njengesikhathi sokushicilela. Njengoba izibuyekezo mayelana ne-coronavirus COVID-19 ziqhubeka nokuvela, kungenzeka ukuthi ulwazi oluthile nezincomo kule ndaba kushintshile kusukela ekushicilelweni kokuqala. Sikukhuthaza ukuthi uhlole njalo izinsiza ezifana ne-CDC, i-WHO, kanye nomnyango wezempilo womphakathi wendawo ukuze uthole imininingwane yakamuva nezincomo.
