Mwana amagona pansi pa aukonde wa udzudzu.Pakafukufuku waposachedwapa, maukonde opangidwa ndi clofenapyr amachepetsa kufala kwa malungo ndi 43% m’chaka choyamba ndi 37% m’chaka chachiwiri kuyerekeza ndi nets wamba wa pyrethroid-only.Photos |Zolemba
Ukonde watsopano womwe ungachepetse udzudzu wosamva mankhwala ophera tizilombo wachepetsa kwambiri matenda a malungo ku Tanzania, asayansi atero.
Poyerekeza ndi ukonde wamba wa pyrethroid-only, maukondewo anachepetsa kwambiri kufala kwa malungo, anachepetsa chiŵerengero cha matenda a ana ndi pafupifupi theka ndi kuchepetsa zochitika zachipatala za matendawa ndi 44 peresenti m’zaka ziŵiri za kuyesedwa kwake.
Mosiyana ndi mankhwala ophera udzudzu, maukonde atsopanowa amapangitsa udzudzu kulephera kudzisamalira, kusuntha kapena kuluma, kuwapha ndi njala, malinga ndi kafukufuku wofalitsidwa mu Marichi mu The Lancet.
Pakafukufukuyu wokhudza mabanja opitilira 39,000 komanso ana opitilira 4,500 ku Tanzania, zidapezeka kuti maukonde ophera tizirombo omwe amakhala kwanthawi yayitali ndi mankhwala awiri, chlorfenapyr ndi chlorfenapyr LLIN, kuchepa kwa malungo kudachepetsedwa ndi 43% poyerekeza ndi ukonde wamba wa pyrethroid-only. , ndi kuchepetsa kachiwiri 37%.
Kafukufukuyu anapeza kuti clofenapyr inachepetsanso chiwerengero cha udzudzu wokhala ndi malungo omwe amagwidwa ndi 85 peresenti.
Malinga ndi asayansi, clofenapyr imachita mosiyana ndi pyrethroids mwa kuchititsa spasms mu minofu ya pterygoid, yomwe imalepheretsa ntchito ya minofu yowuluka.
Dr. Manisha Kulkarni, pulofesa wina wa pa yunivesite ya Ottawa's School of Epidemiology, anati: “Ntchito yathu yowonjezeretsa ukonde wa clofenac ku pyrethroid ili ndi kuthekera kwakukulu kothana ndi malungo ofalitsidwa ndi udzudzu wosamva mankhwala ku Africa mwa ‘kufola’ udzudzu."Zaumoyo wa anthu.
Mosiyana ndi zimenezi, maukonde opangidwa ndi piperonyl butoxide (PBO) pofuna kupititsa patsogolo mphamvu ya pyrethroids amachepetsa matenda a malungo ndi 27% m'miyezi 12 yoyambirira ya mayesero, koma patapita zaka ziwiri pogwiritsa ntchito maukonde okhazikika.
Khoka lachitatu lomwe limathandizidwa ndi pyrethroid ndi pyriproxyfen (udzudzu waukazi wokhala ndi neutered) linali ndi zotsatira zochepa zowonjezera poyerekeza ndi maukonde amtundu wa pyrethroid.Chifukwa chake sichidziwika bwino, koma chikhoza kukhala chifukwa chosakwanira pyriproxyfen yotsalira pa intaneti pakapita nthawi.
“Ngakhale kuti n’zokwera mtengo, mtengo wokwera wa clofenazim LLIN umachepetsedwa ndi ndalama zimene zasungidwa chifukwa chochepetsa chiwerengero cha odwala malungo ofunikira chithandizo.Choncho, mabanja ndi magulu omwe akugawira maukonde a clofenazim ndiwowonjezereka kuti ndalama zonse zikuyembekezeka kukhala zochepa, "anatero gulu la asayansi, omwe akuyembekeza kuti World Health Organization ndi mapulogalamu a malungo adzalandira maukonde atsopano m'madera omwe ali ndi tizilombo toyambitsa matenda. udzudzu.
Zomwe zapeza kuchokera ku National Institute of Medicine, Kilimanjaro Christian University College of Medicine, London School of Hygiene and Tropical Medicine (LSHTM) ndi University of Ottawa ndi nkhani zolandirika ku kontinenti komwe maukonde ogona amalephera kuteteza anthu ku tizirombo .
Ukonde wokhala ndi mankhwala ophera tizirombo unathandiza kupewa 68% ya matenda a malungo ku sub-Saharan Africa pakati pa 2000 ndi 2015. Komabe, pazaka zingapo zapitazi, kuchepa kwa malungo kwayima kapena kusinthiratu m'maiko ena.
Anthu 627,000 adamwalira ndi malungo mu 2020, poyerekeza ndi 409,000 mu 2019, makamaka ku Africa ndi ana.
"Zotsatira zosangalatsazi zikuwonetsa kuti tili ndi chida china chothandiza kuthana ndi malungo," adatero wolemba kafukufukuyu, Dr Jacklin Mosha wa ku Tanzania National Institute of Medical Research.
"Ukonde wa udzudzu wosauluka, wosaluma," wogulitsidwa ngati "Interceptor® G2," ukhoza kubweretsa phindu lalikulu la malungo ku sub-Saharan Africa, gululo linanena.
Komabe, akuti kafukufuku wochulukirapo akufunika kuti ayese kutheka kwa kukulitsa ndikuwonetsa njira zoyendetsera kukana zomwe zimafunikira kuti zisungidwe bwino pakapita nthawi.
Mlembi wina dzina lake Natacha Protopopoff anachenjeza kuti: “Kusamala n’kofunika.” Kukula kwakukulu kwa pyrethroid LLIN zaka 10 mpaka 20 zapitazo kunachititsa kuti matenda a pyrethroid afalikire mofulumira.Vuto tsopano ndikusungabe mphamvu ya clofenazepam popanga njira zowongolera zolimbikitsira. ”
Aka ndi koyamba mwa mayesero angapo ndi ma neti oteteza udzudzu a clofenapyr. Ena ali ku Benin, Ghana, Burkina Faso ndi Côte d'Ivoire.
Madera owuma ndi owuma ndi omwe adakhudzidwa kwambiri, pomwe zokolola za dzikolo zidatsika ndi 70 peresenti.
