Izinja zineempumlo ezibhityileyo kakhulu kwaye ziyakwazi ukuqaphela kwaye zibonise amasuntswana amancinci emoyeni ngevamvo yazo yokujoja. Abahlobo abanemilenze emine baye bangqina amaxesha ngamaxesha ukuba oku kusebenza nakwizifo. Izifundo ezininzi zibonise ukuba izinja zokukhangela zinokusezela usulelo lwe-Covid-19.
Abaqeqeshi abavela kwiZinja zoNyango lwezoNyango baqhube uphononongo ngentsebenziswano neLondon School of Hygiene kunye neTropical Medicine kunye nezinja ezintandathu ukuchonga i-coronavirus kwiimpahla ezinxitywa ngabantu. Isiphumo: Izinja bezichanekile ngama-94.3% exesha, abaqeqeshi banika ingxelo.
Zingasetyenziswa Njani Izinja ukufumanisa i-Covid-19?
Ukukwazi kwezixhobo zokujonga inja ukufumanisa i-Covid-19 ngevumba kunokuba luncedo olukhulu kubantu kwihlabathi liphela. I-Sniffers inokusetyenziswa, umzekelo, kwizikhululo zeenqwelo-moya okanye kwiziganeko ezinkulu kwaye ubonise abantu abosulelekileyo ekungeneni ngesantya sombane. Abahlobo abanemilenze emine nabo babona izigulane ezingenazimpawu.
Kude kube izinja zesiNgesi zilungele ukusetyenziswa ngabantu, kufuneka ziqhubeke nokuqeqesha kunye nokunyusa izinga lokubetha. Abaphandi kwiDyunivesithi yasePennsylvania baphinde bapapasha uphononongo ngo-Epreli olwavavanya amandla ezinja ukufumanisa iimeko ezintle zeCorona. Izinja ezisithoba zokukhangela zasebenzisa iisampulu zomchamo ukufumanisa ngokuchaneka kweepesenti ezingama-96 ukuba umntu une-Covid-19.
Nangona kunjalo, izinja akunakwenzeka ukuba zitshintshe ngokupheleleyo uvavanyo lwe-PCR nanini na kungekudala. Nangona kunjalo, abaphandi bakholelwa ukuba ukudibanisa izinja zenkonzo kunye novavanyo lokuqinisekisa kunokuba luncedo. Ke, phantse iipesenti ezingama-91 zabo bonke abantu abane-SARS-Cov-2 banokuchongwa beneempawu okanye bengenazo.
Uqwalaselo lwe-Covid-19: Khangela Izinja njengoLongezo olunokwenzeka kwiiMvavanyo ze-PCR
“Eyona nto iluncedo kakhulu ezi zinja kukuba zikhawuleza kangakanani ukulibona ivumba losulelo,” utshilo uNjingalwazi uLogan, umbhali ngokubambisana kolu phononongo, ekwabandakanya nezinja zoNyango. "Imodeli yethu icebisa ukuba izinja zisetyenziswa kakuhle njengesixhobo sovavanyo lobunzima obukhawulezayo kunye novavanyo oluqinisekisayo lwe-PCR ebantwini abachonga izinja njengezilungileyo. Oku kunokunciphisa inani lovavanyo lwe-PCR olufunekayo. ”
