NgoZibandlela wezi-2019, kwaqubuka ukutheleleka kwe-SARS-CoV-2 (i-severe acute acute respiratory syndrome 2) eWuhan, esifundazweni saseHubei, eChina, futhi kwasabalala ngokushesha emhlabeni wonke, sekumenyezelwe njengobhubhane yi-WHO ngoMashi 11, 2020. Zingaphezu kwezigidi ezingama-37.8 izehlakalo ezibikwe ngo-Okthoba 14, 2020 emhlabeni jikelele, okwaphumela ekufeni kwabantu abayi-1,081,868 .I-coronavirus entsha ka-2019 (2019-nCoV) isakazeka kalula phakathi kwabantu ngokukhiqizwa kwe-aerosol kusuka kubantu abanaleli gciwane bekhwehlela, bekhuluma noma bethimula besondelene nabanye, futhi inenkathi yokufukamela esukela osukwini olu-1 kuye kweziyi-14.[1]
Ukulandelana kofuzo okwenziwe ku-2019-nCoV, ngoJanuwari 7, 2020, kuvumele ukuthuthukiswa kwethuluzi elisheshayo lokuhlolwa kokuxilonga nge-RT-PCR (reverse transcription polymerase chain reaction).Ngaphandle kokuvimbela ukutheleleka, ukutholakala kwalo kusenesikhathi futhi ngokushesha kubalulekile ekulawuleni ukusabalala kwegciwane .I-Nasopharyngeal swabs (NPS)zisetshenziswa kabanzi futhi zinconyiwe njengesampula ejwayelekile yokuxilongwa kwegciwane lokuphefumula, okubandakanya i-SARS-CoV-2.Kodwa-ke, le ndlela idinga ukusondelana nochwepheshe bezempilo, okwandisa ingozi yokutheleleka ngegciwane futhi kungase kubangele ukungakhululeki, ukukhwehlela ngisho nokopha ezigulini, kungafiseleki kangako ekuqaphelweni kwe-serial viral load.
Amatheukusetshenziswa kokuxilongwa kwegciwane lesandulela ngculazi kukhiqize isithakazelo eminyakeni yamuva, ikakhulukazi ngoba kuyindlela engahlaseli, kulula ukuqoqa futhi inezindleko eziphansi.Ngenxa yokungabikho kwephrothokholi ejwayelekile, ukuqoqwa kwamathe kungatholwa kulokhu: a) amathe avuselelwe noma angavuselelwanga noma ngokuswayipha ngomlomo.Izifo eziningana ezibangelwa amagciwane zingatholakala ematheni, njengegciwane le-Epstein Barr, i-HIV, igciwane le-Hepatitis C, i-Rabies virus, i-Human papillomavirus, i-Herpes simplex virus kanye ne-Norovirus.Ngaphezu kwalokho, kuye kwabikwa ukuthi amathe ayindlela enhle yokuthola i-coronavirus nucleic acid ehambisana nesifo esibucayi sokuphefumula futhi, muva nje, i-SARS-CoV-2.
Izinzuzo zekusetshenziswa amasampula amathe okuxilongwa kwe-SARS-CoV-2, njengokuziqoqa nokuqoqwa ngaphandle kwezibhedlela, ukuthi amasampula amaningi angatholakala kalula futhi kunesidingo esincishisiwe sokuphathwa kochwepheshe bezempilo ngesikhathi sokuqoqwa kwesampula, ukunciphisa ingozi yokudluliselwa kwe-nosocomial, ukunciphisa isikhathi sokulinda ukuhlolwa, nokunciphisa i-PPE, ezokuthutha. nezindleko zokugcina.Enye inzuzo yale ndlela yokuqoqa engahlaseli futhi eyongayo umbono ongcono njengokuqapha komphakathi, kokubili izifo ezingenazimpawu kanye nokuqondisa ukuphela kokuvalelwa.
