Kev tshawb fawb ua ntej luam tawm ntawm medRxiv lub lim tiam dhau los (uas tseem tsis tau tshuaj xyuas dua) ntxaws ntxaws li cas C.1.2 kev hloov pauv hloov pauv los ntawm C.1, qhov kev nyuab tom qab thawj nthwv dej ntawm SARS-CoV-2 kis (tus kab mob uas ua rau COVID-19) hauv South Africa .Cov kab mob C.1 tau kuaj pom zaum kawg hauv South Africa thaum Lub Ib Hlis xyoo no, raws li tsab ntawv ceeb toom, nrog C.1.2 hom kab mob tshwm sim hauv lub tebchaws thaum lub Tsib Hlis.

Qhov no txhais li cas, raws nraim? Zoo, rau qhov pib, Lub Tsev Haujlwm Saib Xyuas Kab Mob thiab Tiv Thaiv tau lees paub qhov sib txawv ntawm COVID-19 raws li VOCs raws li cov pov thawj uas txhawb nqa kev kis tus kabmob, kab mob hnyav dua (kev nce siab hauv tsev kho mob lossis kev tuag), thiab txo cov kev kho mob.

Thiab, ICYDK, cov protein muaj nyob rau sab nraud ntawm tus kab mob thiab tuaj yeem txuas rau koj cov cell, yog li ua rau COVID-19. Ntau qhov kev hloov pauv thiab kev tshem tawm hauv cov protein ntau "tau pom nyob rau hauv lwm yam VOCs thiab cuam tshuam nrog kev nce kis tau zoo thiab txo qis kev tsis txaus ntseeg," raws li kev tshawb fawb.

Dab tsi ntxiv, cov kws paub txog kab mob sib kis zoo li tsis muaj kev ceeb toom dhau los ntawm qhov no. Amesh A. Adalja, MD, tus kws paub txog kab mob sib kis thiab tus kws tshaj lij ntawm Johns Hopkins Center for Health Security hais tias "Muaj txog 100 qhov xwm txheej tau tshaj tawm thoob ntiaj teb thiab nws tsis zoo li yuav nce ntxiv raws li Delta ua tus tswj hwm lwm yam."

"Lub sijhawm tam sim no, qhov no tsis yog qhov ua rau muaj kev txhawj xeeb," ntxiv William Schaffner, MD, tus kws tshaj lij kis mob thiab tus xibfwb ntawm Vanderbilt University School of Medicine. "Qhov ntau peb saib, ntau qhov kev sib txuas ntawm caj ces peb ua, qhov ntau ntawm cov kev hloov pauv no yuav tshwm sim. Ib txhia ntawm lawv yuav kis tau thiab cov lus nug yog, 'Puas yog lawv mus khaws chav?"

Dr. Schaffner kuj taw qhia tias Lambda variant, piv txwv li, "tau tawm mus ib ntus, tab sis nws tseem tsis tau khaws cov chav." Uas tau hais, nws sau tseg tias nws tsis meej yog C.1.2 yuav ua raws txoj hauv kev zoo sib xws. "Nws tau kis me ntsis tab sis qee qhov kev hloov pauv no yuav kis me ntsis thiab tsis ua ntau ntxiv," hais tias Dr. Schaffner.

Dr. Adalja sau tseg tias tsis muaj ntau ntxiv nrog C.1.2 tam sim no. "Lub sijhawm no, tsis muaj ntaub ntawv txaus los ntsuas seb nws txoj hauv kev yav tom ntej yuav zoo li cas," nws hais. "Txawm li cas los xij, Delta variant, vim tias nws lub zog ua rau nws nyuaj rau lwm yam sib txawv kom tau txais ib qho foothold."
