FDA yavomereza mankhwala atsopano a nthomba

Lero, bungwe la US FDA lalengeza kuti lavomereza mankhwala atsopano a SIGA Technologies a TPOXX (tecovirimat) pochiza nthomba. Ndikoyenera kunena kuti iyi ndi mankhwala atsopano a 21 ovomerezedwa ndi US FDA chaka chino komanso mankhwala atsopano oyamba ovomerezedwa pochiza nthomba.

Dzina la nthomba, owerenga makampani azachipatala sadzadziwika. Katemera wa nthomba ndiye katemera woyamba wopangidwa bwino ndi anthu, ndipo tili ndi chida chopewera matenda oopsa awa. Kuyambira pomwe katemera wa nthomba adaperekedwa, anthu apambana nkhondo yolimbana ndi mavairasi. Mu 1980, Bungwe la Zaumoyo Padziko Lonse linalengeza kuti tachotsa chiwopsezo cha nthomba. Mtundu uwu wa matenda opatsirana, womwe wakhudzidwa kwambiri ndipo wakhala ukukambidwa, watha pang'onopang'ono kuchokera m'malingaliro a anthu.

Koma chifukwa cha zovuta za dziko lonse m'zaka makumi angapo zapitazi, anthu anayamba kuda nkhawa kuti kachilombo ka nthomba kangapangidwe kukhala zida zamoyo, zomwe zingawopseze miyoyo ya anthu wamba. Chifukwa chake, anthu adaganizanso zopanga mankhwala omwe angathandize pochiza nthomba pakagwa ngozi. TPOXX idayamba kugwiritsidwa ntchito. Monga mankhwala oletsa mavairasi, imatha kuthana bwino ndi kufalikira kwa kachilombo ka variola m'thupi. Kutengera ndi kuthekera kwake, mankhwalawa atsopano apatsidwa ziyeneretso zachangu, ziyeneretso zowunikiranso patsogolo, komanso ziyeneretso za mankhwala amasiye.

Kugwira ntchito bwino ndi chitetezo cha mankhwala atsopanowa kwayesedwa m'mayesero a nyama ndi anthu, motsatana. Mu zoyeserera za nyama, nyama zomwe zili ndi TPOXX zimakhala ndi moyo wautali kuposa zomwe zidapatsidwa mankhwala a placebo zitadwala kachilombo ka variola. Mu zoyeserera za anthu, ofufuza adalemba anthu 359 odzipereka athanzi (opanda matenda a nthomba) ndipo adawapempha kuti agwiritse ntchito TPOXX. Kafukufuku wasonyeza kuti zotsatira zoyipa kwambiri ndi mutu, nseru, ndi kupweteka m'mimba popanda zotsatira zoyipa kwambiri. Kutengera ndi kugwira ntchito bwino komwe kwawonetsedwa m'zoyeserera za nyama komanso chitetezo chomwe chawonetsedwa ndi zoyeserera za anthu, FDA idavomereza kuyambitsa mankhwalawa atsopano.

"Poyankha kuopsa kwa uchigawenga wa bioterrorism, Congress yatenga njira zowonetsetsa kuti tizilombo toyambitsa matenda tikugwiritsidwa ntchito ngati zida, ndipo tapanga ndikuvomereza njira zotsutsana nazo. Kuvomerezedwa kwa lero kukuyimira gawo lalikulu pakuyesetsa kumeneku!" Mtsogoleri wa FDA Scott Gottlieb Dokotalayo anati: "Iyi ndi mankhwala atsopano oyamba kupatsidwa ndemanga yoyamba ya 'Material Threat Medical Countermeasure'. Kuvomerezedwa kwa lero kukuwonetsanso kudzipereka kwa FDA kuonetsetsa kuti tili okonzeka ku vuto la thanzi la anthu ndikupereka chitetezo panthawi yake. Mankhwala atsopano ogwira mtima."

Ngakhale kuti mankhwala atsopanowa akuyembekezeka kuchiza nthomba, tikuyembekezerabe kuti nthomba sidzabwereranso, ndipo tikuyembekezera tsiku limene anthu sadzagwiritsanso ntchito mankhwala atsopanowa.
