Oososayensi baseMelika baxele ubukho bamanqanaba amabini efom eqatha ye-COVID-19. Uphononongo olunxulumene noogqirha oluchaza ukusweleka kwezigulana lupapashwe kwiphephancwadi lezenzululwazi i-Nature Communications.
Ukuhlalutya ifuthe le-coronavirus emzimbeni, iingcali kwisibhedlele iMassachusetts General Hospital ziye zafunda izixhobo ezichaziweyo zezigulana ezingama-24 ezibulewe yi-COVID-19. Ngenxa yolwazi oluneenkcukacha ngezi datha, oogqirha babenako ukubona indawo ekuyo intsholongwane ye-SARS-CoV-2 kwiisampulu zemiphunga kwizigulana ezine-coronavirus.
Ngokusekwe kwidatha efunyenweyo, izazinzulu zifumanise ukuba kukho izigaba ezibini zohlobo olubi lwe-coronavirus. Inqanaba lokuqala limiselwa ngamanqanaba aphezulu wentsholongwane emiphungeni, ngenxa yoko umzimba uvuselela ukubonakaliswa kofuzo olufunekayo ukuze kubangele ukuphendula komzimba. Kwinqanaba lokugqibela, akukho nxalenye yentsholongwane, kodwa amathuba okufa ahlala ephezulu kakhulu. Oku kungenxa yenqanaba eliphezulu lomonakalo wemiphunga.
Ngokutsho koogqirha, ikhosi yohlobo olomeleleyo lwe-COVID-19 kubantu abohlukeneyo inokwahluka. "Impendulo yomzimba kwintsholongwane ingahluka, nkqu nakwiindawo ezahlukeneyo zemiphunga," watsho umbhali wophando uGqirha David T. Ting. Kwakhona, iingcali ziye zafumanisa ukuba ukusetyenziswa kwamachiza antiviral-umzekelo, i-remdesivir-inokusebenza kuphela kwinqanaba lokuqala lesi sifo.
Kwangoko, oogqirha baseRussia bavavanya ifuthe le-coronavirus kubomi besigulana. Ngokutsho kwe-immunologist-allergist uVladimir Bolibok, ixesha lokuphila kwabo banayo i-COVID-19 inokuncitshiswa, ukuba isigulana siba nezifo ezingapheliyo.
