Ngesikhathi sobhubhane lwe-Covid-19, iziphathimandla zaseNdiya ziphikelele ekusebenziseni izivivinyo ze-RT-PCR ezibiza kakhulu kodwa ezinembe kakhudlwana esikhundleni sokuhlolwa kwe-antigen (RAT) eshibhile kodwa ebucayi kancane ukugcwalisa izintuba esivivinyweni.
Kodwa manje, ithimba labacwaningi abavela e-Sonipat Ashoka University kanye ne-National Center for Biological Sciences (NCBS) e-Bangalore baye basebenzisa amamodeli wokubala ukuze babonise ukuthi ngisho nokusetshenziswa okuhlakaniphile kokuhlolwa kwe-antigen okusheshayo (RAT) kungaveza imiphumela emihle ngombono we-epidemiological.Uma ukuhlolwa kwenziwa ngokulinganayo.
Leli phepha, elibhalwe nguPhilip Cherian noGautam Menon base-Ashoka University kanye noSudeep Krishna we-NCBS, lishicilelwe ku-PLoS Journal of Computational Biology ngoLwesine.
Nokho, ososayensi bayaphikelela kwezinye izimo.Okokuqala, iRAT kufanele ibe nokuzwela okunengqondo, abantu abaningi kufanele bahlolwe (cishe u-0.5% wabantu ngosuku), labo abathole amasende kufanele babekwe bodwa kuze kutholakale imiphumela, futhi ukuhlolwa kufanele kuhambisane nabanye abangasebenzisi izidakamizwa abagqoke imaski futhi ukugcina ibanga lomzimba Kanye nokunye ukungenelela.
“Esiqongweni salolu bhubhane, kufanele senze izivivinyo eziphindwe kahlanu (i-RAT) kunanamuhla.Lokhu cishe izigidi ezingama-80 kuye kweziyi-9 ngosuku.Kepha uma inani lamacala lehla, ngokwesilinganiso, unganciphisa izivivinyo,” kusho uMenon etshela iBusinessLine.
Nakuba ukuhlola kwe-RT-PCR kuzwela kakhulu kunokuhlola okusheshayo kwe-antigen, kubiza kakhulu futhi akunikezi imiphumela esheshayo.Ngakho-ke, inhlanganisela enembile yokuhlola edingekayo ukuze kuthuthukiswe imiphumela kuyilapho kucatshangelwa izithiyo zezindleko bekungakacaci.
Ngesikhathi sobhubhane lwe-Covid, izifundazwe ezahlukahlukene zaseNdiya bezilokhu zisebenzisa inhlanganisela ehlukile ye-RT-PCR ne-RAT.Amazwe amaningi aya ngokuya ethembela kuma-RAT angazweli kangako—ngoba ashibhe kakhulu kune-RT-PCR—okuyindawo yombango phakathi kwawo noMnyango Wezempilo Wenhlangano.
Ukuhlaziya kwabo kubonise ukuthi mayelana nokuhlonza izifo eziphelele, ukusebenzisa kuphela ukuhlolwa kwe-antigen okusheshayo kungafinyelela imiphumela efana naleyo esebenzisa i-RT-PCR kuphela—inqobo nje uma isibalo sabantu abahloliwe sikhulu ngokwanele.Lokhu kuphakamisa ukuthi ohulumeni emazweni anemali engenayo ephansi naphakathi bangakwazi ukukhulisa ukuhlolwa ngokugxila ekusebenziseni izivivinyo ezingazweli kangako ezinikeza imiphumela esheshayo, kunokuba basekele i-RT-PCR ukuze izuze imiphumela engcono kakhulu.
Umbhali uphakamisa ukuthi uhulumeni kufanele aqhubeke nokuhlola inhlanganisela yokuhlola ehlukene.Uma kubhekwa ukuthi izindleko zokuhlola ziyehla, le nhlanganisela ingaphinda ilinganiswe ngezikhathi ezithile ukuze kuqashwe ukuthi yikuphi ukonga kakhulu.
“Ukuhlola kuhlala kuba ngcono, futhi ukuhwebelana kulungele ukuhlolwa okusheshayo, ngisho noma kungenazwelo kangako,” kusho uMenon."Ukulingisa umthelela wokusebenzisa inhlanganisela yokuhlola ehlukene, kuyilapho ukhumbula izindleko ezihambisanayo, kungasikisela izinguquko ezithile zenqubomgomo ezizoba nomthelela omkhulu ekuguquleni umsuka walolu bhubhane."
