Cov txiaj ntsig zoo mob qa mus ntxiv yog dab tsi? Dab tsi yog qhov txawv ntawm cov qa zoo mus rau hauv lub caj pas thiab daim ntawv npog uas tau lees paub los ntawm COVID-19?
Qhov ncauj caj pas zoo qhia tias muaj cov kabmob
GG quot; Tom qab qhov COVID-19 tawg lawm, kev khaws qa mus rau hauv lub qa yog tam sim no tus qauv tseem ceeb rau cov kab mob viral nucleic acid nyob rau hauv Suav teb.Yog hais tias muaj caj pas zoo mob qog txhais tau tias yog kuaj nucleic acid, ces cov 45 yog tus tshiab Coronavirus." Ib tus kws tshaj lij hauv kev tiv thaiv kabmob hauv lub cev tau qhia Science thiab Technology Txhua Hnub.
Lub nucleic acid test zoo li cas txhais tau tias? Nws tau qhia tias tus kabmob coronavirus yog muaj cov protein thiab RNA, uas yog lub luag haujlwm rau cov luam tawm tus kab mob.Qhov cov nqaijrog sab nraud ob leeg tswj hwm tus qauv ntawm tus kabmob thiab tiv thaiv sab hauv RNA.So qhov kev ntsuam xyuas nucleic acid yog qhov kev ntsuam xyuas ncaj qha rau qhov muaj tus kabmob, uas txhais tau tias mob caj pas zoo qhia tias muaj tus kabmob.
Kab mob coronavirus yog feem ntau kis los ntawm kev ua pa, thiab pharynx yog qhov chaw uas cov kab mob zoo li no. Cov khoom no yog ua los ntawm ntsaws tawm ib qho me me ntawm kev zais tawm ntawm pharynx nrog cov paj rwb kho mob thiab tom qab ntawd kuaj cov hnoos qeev.
Cov kws tshaj lij-tshaj lij hais rau cov kws qhia ntawv tau hais tias ob lossis ntau ntau qhov kev kuaj qa nqaij hauv lub caj pas feem ntau yuav tsum tau txheeb xyuas tus neeg muaj tus mob, thiab ob txoj kev mob caj pas tau zoo yog suav tias yog kis mob, thiab ob txoj kev kuaj mob nyob nruab nrab yog 24 teev sib nrug. kuaj cov kua qaub kuj yog qhov ntsuas kev tawm.
Cov neeg uas muaj caj pas caj pas mus rau hauv lub qa zoo tuaj yeem paub tseeb lossis asymptomatic
GG quot; Cov neeg pom kev zoo-swab yuav yog asymptomatic lossis muaj ib kis uas pom tseeb ntawm COVID-19." Cheng Zhenshun, tus thawj coj ntawm Lub Tsev Haujlwm Tiv Thaiv Kev Kho Mob thiab Kev Tu Mob Hlwb Lub Tsev Kho Mob ntawm Central South Tsev Kho Mob ntawm Wuhan University thiab tus thawj coj ntawm Cov Chaw Pab Kho Mob ntawm Wuhan Medical Association, tau taw qhia tias qhov kev hloov caj pas zoo tsis txhais tau tias yog kis mob coVID-19 Cov.
GG quot; Yog tias ib tug neeg' s mob caj pas mob qa o tau zoo rau NUCLEic acid tab sis tsis muaj cov kev kuaj mob, xws li ua npaws lossis mob ua paug, thiab CT scan ntawm lub ntsws tsis qhia pom tseeb tias muaj tus kab mob viral, ces nws lossis nws yog asymptomatic," Cheng piav.
Raws li kev piav qhia ntawm kev kuaj mob rau kev tshawb pom tseeb COVID-19 nyob rau COVID-19 Kev kuaj mob thiab kho raws txoj cai (sim version 7), cov neeg kawm ntawv uas kuaj pom zoo rau NUCLEic acid xav tau los ua ke lawv cov kev soj ntsuam nrog lwm qhov tshawb pom xws li ntsws CT, cheng ntxiv xwb. Tsuas yog cov uas ua tau raws li kev kuaj mob rau COVID-19 tuaj yeem suav hais tias yog cov ntaub ntawv lees paub.
GG quot; Raws li kev tshawb nrhiav tsis ntev los no hauv Wuhan, cov neeg mob asymptomatic kis tau tus kab mob tsis muaj zog, tab sis cov neeg mob asymptomatic yuav tig los ua mob, yog li lawv yuav raug cais tawm rau kev soj ntsuam. Feem ntau hais lus, cov neeg mob asymptomatic tuaj yeem muab cais tawm yam tsis tau kho tshwj xeeb." Cheng Zhenshun hais ntxiv.
