Namhlanje, i-FDA yase-US ibhengeze ulwamkelo lwechiza elitsha le-SIGA Technologies TPOXX (tecovirimat) kunyango lwe-smallpox. Kufanelekile ukukhankanya ukuba eli lichiza elitsha lama-21 elivunywe yi-US FDA kulo nyaka kunye nechiza elitsha lokuqala elivunyiweyo kunyango lwe-smallpox.
Igama le-smallpox, abafundi beshishini le-biomedical abayi kuba bangaqhelekanga. Isitofu sokugonya sengqakaqha sisitofu sokuqala esiphuhliswe ngempumelelo ngabantu, kwaye sinesixhobo sokuthintela esi sifo sibulalayo. Ukususela ekugonyweni kogonyo lwengqakaqha, abantu baye baphumelela kumlo ochasene neentsholongwane. Ngowe-1980, iWorld Health Organization yenza isaziso sokuba sisiphelisile isisongelo sengqakaqha. Olu hlobo lwesifo esosulelayo, oluye lwachaphazeleka ngokubanzi nekwathethwa ngalo, luye lwaphela ngokuthe ngcembe eluntwini.
Kodwa ngenxa yokuntsonkotha kwemeko yehlabathi kula mashumi eminyaka, abantu baqalisa ukuba nexhala lokuba intsholongwane yengqakaqha isenokwenziwa ibe zizixhobo zebhayoloji, isongela ubomi babantu abaqhelekileyo. Ngoko ke, abantu baye bagqiba ekubeni benze ichiza elinokunyanga ingqakaqha kwimeko kaxakeka. I-TPOXX yabakho. Njengechiza le-antiviral, inokujolisa ngokufanelekileyo ukusasazeka kwentsholongwane ye-variola emzimbeni. Ngokusekwe kwisakhono salo, eli chiza litsha linikwe imigangatho yemfundo ekhawulezayo, iziqinisekiso zophononongo oluphambili, kunye neziqinisekiso zamachiza enkedama.
Ukusebenza kunye nokhuseleko lweli chiza elitsha livavanyiwe kwizilingo zezilwanyana kunye nabantu, ngokulandelelanayo. Kuvavanyo lwezilwanyana, izilwanyana ezosulelwe yi-TPOXX zihlala ixesha elide kunezo ziphathwa nge-placebo emva kokusuleleka yintsholongwane ye-variola. Kwizilingo zabantu, abaphandi baqesha amavolontiya aphilileyo angama-359 (ngaphandle kosulelo lwe-smallpox) kwaye babacela ukuba basebenzise i-TPOXX. Uphononongo lubonise ukuba iziphumo zecala eziqhelekileyo ziyintloko, isicaphucaphu, kunye neentlungu zesisu ngaphandle kwemiphumo emibi. Ngokusekelwe kwimpumelelo ebonakaliswe kwiimvavanyo zezilwanyana kunye nokhuseleko olubonakaliswe ngamalingo abantu, i-FDA yavuma ukuqaliswa kweyeza elitsha.
"Ekuphenduleni ingozi ye-bioterrorism, iCongress ithathe amanyathelo okuqinisekisa ukuba i-pathogens isetyenziswa njengezixhobo, kwaye siye saphuhlisa kwaye savuma amanyathelo okuthintela. Ukwamkelwa kwanamhlanje kubonisa isiganeko esibalulekileyo kule migudu!” UMlawuli we-FDA uScott Gottlieb Ugqirha uthe: “Eli lichiza lokuqala elitsha ukuwongwa ngophononongo oluphambili lwe-'Material Threat Medical Countermeasure'. Ulwamkelo lwanamhlanje lukwabonisa ukuzibophelela kwe-FDA ekuqinisekiseni ukuba siyilungele ingxaki yezempilo yoluntu kunye nokubonelela ngokhuseleko kwangexesha. Iimveliso zamachiza amatsha asebenzayo.”
Nangona eli chiza litsha kulindeleke ukuba linyange ingqakaqha, sisalindele ukuba ingqakaqha ayisayi kuphinda ibuye, kwaye sijonge phambili kwimini apho abantu bengasokuze balisebenzise eli chiza litsha.
