Rudzi rutsva rwemambure epamubhedha anogona kuderedza umhutu husingaurayiwi nemishonga yechinyakare rwakaderedza zvakanyanya utachiona hwemarariya muTanzania, masayendisiti anoti.
Kuenzaniswa nemambure epyrethroid-chete, mambure akaderedza zvakanyanya kuwanda kwemarariya, akacheka huwandu hwehutachiwana hwevana nehafu uye akaderedza zvikamu zvechipatara zvechirwere ne44 muzana mumakore maviri ekuedzwa kwacho.
Kusiyana nemishonga inouraya umhutu, mambure matsva anoita kuti umhutu dzisakwanise kuzviriritira, kufamba kana kuruma, zvichivauraya nenzara, sekutsvagurudza kwakabudiswa muna Kurume muThe Lancet.
Muongororo iyi inosanganisira dzimba dzinodarika zviuru makumi matatu nepfumbamwe nevana vanodarika zviuru zvina nemazana mashanu muTanzania, zvakaonekwa kuti mambure emishonga ekuuraya zvipembenene anogara kwenguva refu akabatwa nemishonga miviri, chlorfenapyr nechlorfenapyr LLIN, akaderedza kupararira kweMalaria kwakadzikira nechikamu che43% kana zvichienzaniswa nemambure epyrethroid-only. , uye kuderedzwa kwechipiri kwe37%.
Ongororo iyi yakaratidza kuti clofenapyr yakaderedzawo humhutu hune malaria hwakabatwa nechikamu che85 percent.
Maererano nemasayendisiti, clofenapyr inoshanda zvakasiyana nepyrethroids nekuita kuti spasms mumisumbu yepterygoid, iyo inodzivirira kushanda kwemhasuru dzendege.Izvi zvinodzivirira umhutu kuti usasangana kana kuruma mauto avo, izvo zvinogona kupedzisira zvaita kuti vafe.
Dr. Manisha Kulkarni, mumwe purofesa paUniversity of Ottawa's School of Epidemiology, akati: “Basa redu rekuwedzera clofenac kumambure epyrethroid ane simba guru rokudzora marariya inoparadzirwa neumhutu husingaurayiwi nemishonga muAfrica kupfurikidza noku‘pedza’ mosquito.“Utano Hwevanhu.
Kusiyana neizvi, mambure epamubhedha akabatwa nepiperonyl butoxide (PBO) kuti awedzere kushanda kwepyrethroids akadzikisa utachiona hwemalaria nechikamu che27% mukati memwedzi gumi nemiviri yekutanga yekuedzwa, asi mushure memakore maviri nekushandiswa kwemambure akajairika.
Mambure echitatu akabatwa nepyrethroid uye pyriproxyfen (neutered female mosquitoes) yakanga ine zvishoma zvekuwedzera zvichienzaniswa neyakajairwa pyrethroid nets.Chikonzero chacho hachina kunyatsojeka, asi chinogona kunge chiri nekuda kwekusakwana pyriproxyfen yakasara paIndaneti nekufamba kwenguva.
“Kunyange zvazvo zvichidhura, mutengo wepamusoro we clofenazim LLIN unodzikiswa nemari yakachengetwa kubva mukuderedza nhamba yezvirwere zvemalaria zvinoda kurapwa.Naizvozvo, mhuri nenzanga dziri kugovera mambure eclofenazim dzine mukana wokuve Mutengo wose unotarisirwa kuve wakaderera,” rakadaro boka revasayendisiti, vanotarisira kuti World Health Organization uye zvirongwa zvokudzora marariya zvichagamuchira mambure matsva munzvimbo dzine utachiona husingaurayiwi nemishonga. umhutu.
Zvakawanikwa kubva kuNational Institute of Medicine, Kilimanjaro Christian University College of Medicine, London School of Hygiene and Tropical Medicine (LSHTM) uye University of Ottawa inhau dzinogamuchirwa mukondinendi umo mambure epamubhedha akajairwa anotadza kudzivirira vanhu kubva kumaparasite.
Mambure ane mishonga yekuuraya zvipembenene akabatsira kudzivirira 68% yezvirwere zvemalaria muSouth Africa yeSahara pakati pa2000 na2015. Mumakore mashoma apfuura, zvisinei, kuderera kwehuwandu hwemalaria kwakamira kana kutodzokera kumashure mune dzimwe nyika.
Vanhu 627,000 vakafa nemarariya muna 2020, zvichienzaniswa ne409,000 muna 2019, kunyanya muAfrica nevana.
“Zvabuda zvinofadza izvi zvinoratidza kuti tine chimwe chishandiso chinoshanda chekubatsira kudzora marariya,” akadaro munyori mukuru weongororo iyi, Dr Jacklin Mosha vekuTanzania National Institute of Medical Research.
"Mambure eumhutu husingabhururuke, husingaruma," inotengeswa se "Interceptor® G2," inogona kutungamirira kune zvakakosha kudzora marariya muAfrica yekumaodzanyemba kweSahara, boka racho rakati.
Nekudaro, vanoti tsvakiridzo yakawanda inodiwa kuyedza kugona kwekukwira kumusoro uye kupa zano rekudzivirira manejimendi nzira dzinodiwa kuchengetedza kushanda mukufamba kwenguva.
“Kuchenjerera kunodiwa,” anonyevera kudaro mumwe munyori anonzi Natacha Protopopoff.” Kuwedzera kukuru kweiyo standard pyrethroid LLIN makore 10 kusvika ku20 apfuura kwakakonzera kupararira nokukurumidza kwepyrethroid resistance.Dambudziko ravepo nderekuchengetedza kushanda kwe clofenazepam nekugadzira hurongwa hwekuramba kutonga.
