A FDA amavomereza mankhwala atsopano a nthomba

Lero, US FDA yalengeza kuvomereza kwa mankhwala atsopano a SIGA Technologies TPOXX (tecovirimat) ochizira nthomba. Ndikoyenera kutchula kuti awa ndi mankhwala atsopano a 21 ovomerezedwa ndi US FDA chaka chino komanso mankhwala atsopano ovomerezeka ochizira nthomba.

Dzina la nthomba, owerenga biomedical makampani sadzakhala achilendo. Katemera wa nthomba ndiye woyamba kupangidwa bwino ndi anthu, ndipo tili ndi chida chopewera matendawa. Chiyambireni katemera wa nthomba, anthu apambana pankhondo yolimbana ndi ma virus. Mu 1980, bungwe la World Health Organization linalengeza kuti tathetsa vuto la nthomba. Matenda opatsirana amtunduwu, omwe akhala akukhudzidwa kwambiri ndipo akhala akukambidwa, pang'onopang'ono achoka m'maganizo a anthu.

Koma chifukwa cha kusokonekera kwa zinthu padziko lonse m’zaka makumi angapo zimenezi, anthu anayamba kuda nkhaŵa kuti kachilombo ka nthomba kadzasanduka zida za tizilombo toyambitsa matenda, zomwe zikuwopseza miyoyo ya anthu wamba. Chifukwa chake, anthu adaganizanso zopanga mankhwala omwe amatha kuchiza nthomba pakagwa mwadzidzidzi. TPOXX idayamba kukhalapo. Monga mankhwala oletsa tizilombo toyambitsa matenda, amatha kulimbana ndi kufalikira kwa kachilombo ka variola m'thupi. Kutengera ndi kuthekera kwake, mankhwala atsopanowa apatsidwa ziyeneretso zofulumira, ziyeneretso zowunikira patsogolo, komanso ziyeneretso zamankhwala amasiye.

Mphamvu ndi chitetezo cha mankhwala atsopanowa ayesedwa mu mayesero a nyama ndi anthu, motsatira. Poyesa nyama, nyama zomwe zili ndi TPOXX zimakhala ndi moyo wautali kuposa zomwe zimathandizidwa ndi placebo pambuyo pa kachilombo ka variola. M'mayesero aumunthu, ochita kafukufuku adapeza anthu odzipereka athanzi a 359 (popanda matenda a nthomba) ndipo adawapempha kuti agwiritse ntchito TPOXX. Kafukufuku wasonyeza kuti zotsatira zofala kwambiri ndi mutu, nseru, ndi kupweteka kwa m'mimba popanda mavuto aakulu. Kutengera mphamvu zomwe zawonetsedwa pazoyeserera zanyama komanso chitetezo chowonetsedwa ndi mayesero a anthu, a FDA adavomereza kukhazikitsidwa kwa mankhwala atsopano.

"Poyankha kuopsa kwa bioterrorism, Congress yachitapo kanthu pofuna kuonetsetsa kuti tizilombo toyambitsa matenda tikugwiritsidwa ntchito ngati zida, ndipo tapanga ndi kuvomereza njira zopewera. Mkulu wa FDA a Scott Gottlieb Dokotalayo anati: “Awa ndi mankhwala atsopano oyamba kupatsidwa kuwunika koyambirira kwa 'Material Threat Medical Countermeasure.'

Ngakhale kuti mankhwala atsopanowa akuyembekezeka kuchiza nthomba, tikuyembekezerabe kuti nthombayo sidzabweranso, ndipo tikuyembekezera mwachidwi tsiku limene anthu sadzagwiritsa ntchito mankhwala atsopanowa.
