PLA ntxeem tau microneedles: nrhiav tau sai ntawm covid-19 tshuaj tiv thaiv tsis muaj ntshav kuaj
Cov kws tshawb fawb Nyij Pooj tau tsim cov tshuaj tiv thaiv kab mob tshiab rau kev tshawb nrhiav sai thiab ntseeg tau ntawm tus kabmob tshiab tshiab yam tsis tas yuav kuaj ntshav. Cov txiaj ntsig kev tshawb fawb tsis ntev los no tau luam tawm hauv phau ntawv xov xwm Science report. Kev txheeb xyuas tsis zoo ntawm cov neeg muaj tus kabmob coronavirus tau txwv lub ntiaj teb cov lus teb rau COVID-19, uas ua rau muaj kev cuam tshuam ntau dua los ntawm tus kabmob asymptomatic siab (16% - 38%). Txog tam sim no, txoj kev sim tseem ceeb yog khaws cov qauv los ntawm kev so lub qhov ntswg thiab caj pas. Txawm li cas los xij, daim ntawv thov ntawm txoj kev no raug txwv los ntawm nws lub sijhawm tshawb pom ntev (4-6 teev), tus nqi siab thiab cov kev xav tau rau cov cuab yeej siv thiab cov neeg ua haujlwm kho mob, tshwj xeeb tshaj yog nyob rau hauv cov tebchaws uas muaj peev txheej tsawg. Tom qab ua pov thawj tias cov kua dej interstitial yuav haum rau cov tshuaj tiv thaiv ...
