UAI tuaj yeem ua rau cov menyuam yaus muaj kev pheej hmoo ntawm lub plawv nres thiab lwm yam teeb meem loj vim tias lawv txoj kev ua pa me me tau yooj yim thaiv, cov kws tshawb fawb tau hais.
Feem pua ntawm cov menyuam yaus nyob hauv tsev kho mob nrog Covid-19 uas tseem pom tias muaj UAI tau nce los ntawm 1.5% nyob rau lub sijhawm ua ntej omicron (Lub Peb Hlis 1, 2020 txog Lub Kaum Ob Hlis 25, 2021) mus rau 4.1% nyob rau lub sijhawm omicron (Lub Kaum Ob Hlis 26, 2021 rau Lub Ob Hlis 17, 2022), raws li kev tshawb fawb.
Cov kws tshawb fawb tseem pom tias omicron nyiam ua rau UAI rau cov menyuam yaus - lub hnub nyoog nruab nrab ntawm tus menyuam pw hauv tsev kho mob nrog Covid-19 thiab UAI poob li ntawm 4 xyoo thiab tsib lub hlis thaum lub sijhawm ua ntej omicron txog li 2 xyoos thiab ib hlis thaum lub sijhawm omicron. lub sij hawm.
Zuag qhia tag nrho, 21.1% ntawm cov menyuam yaus nyob hauv tsev kho mob nrog Covid-19 thiab UAI tau tsim cov kab mob hnyav uas xav tau kev ntsuas xws li ntxig lub raj rau hauv lub ntsws los pab ua pa.

Kev ntsuas qhov sib txheeb qhov hnyav ntawm omicron variant tau ua rau muaj kev sib tw rau cov kws tshawb fawb. Txawm li cas los kev tshawb fawb ua nyob ib ncig ntawm lub sij hawm omicron tsim nws dominance Hauv Teb Chaws Asmeskas tau qhia tias nws tsuas yog kis tau yooj yim dua thiab tsis tshua muaj mob hnyav ntawm cov delta variant, kev txhawj xeeb sai sai tshwm sim txog omicron qhov cuam tshuam rau menyuam yaus.

Andrew Pavia, tus thawj coj ntawm University of Utah Health's Division of Pediatric Infectious Diseases, kuj pom tias hais tias omicron yuav kis tau rau sab sauv txoj hlab ntsws yooj yim dua li lub ntsws, txo qhov kev pheej hmoo ntawm mob ntsws loj heev tab sis ua rau muaj kev pheej hmoo ntawm cov kab mob ua pa sab sauv, uas cov menyuam yaus tshwj xeeb tshaj yog muaj kev phom sij. Thaum tus nqi ntawm Covid-19-ua rau UAI ntawm cov menyuam yaus tsis yog "dhau siab heev," kev tshawb fawb ntxiv tuaj yeem pab qhia kev kho mob rau cov neeg mob hluas, sau cov sau phau ntawv. JAMA Pediatrics kawm.

Thaum lub omicron variant tau nce tus kab mob ntawm cov menyuam yaus, qhov kev pheej hmoo ntawm kev mob hnyav ntawm cov menyuam yaus tseem qis heev. Cov ntaub ntawv los ntawm CDC thiab cov JAMA Pediatrics txoj kev tshawb fawb qhia tias tus me nyuam txoj kev pheej hmoo mus pw hauv tsev kho mob nrog Covid-19 yog kwv yees li 1 ntawm 14,085, thaum tus me nyuam txoj kev pheej hmoo mus pw hauv tsev kho mob nrog Covid-19 thiab txhim kho UAI thiab cov tsos mob hnyav yog kwv yees li 1 ntawm 10 lab. Qhov kev pheej hmoo ntawm kev mob hnyav ntawm cov menyuam yaus nyob hauv tsev kho mob nrog Covid-19 kuj tau poob rau kwv yees li 3.4% thaum lub sijhawm omicron, nqis los ntawm 38.8% thaum lub sijhawm ua ntej omicron, raws li cov ntaub ntawv.
