Tau ntau xyoo lawm,tshuaj tua kab-kho txaj nets thiab cov kev pab cuam tshuaj tua kab hauv tsev yog ib qho tseem ceeb thiab dav siv tau zoo los tswj cov yoov tshaj cum uas kis tus kab mob malaria, kab mob thoob ntiaj teb puas tsuaj. Tab sis rau ib lub sij hawm, cov kev kho mob no kuj txwv tsis pub cov kab hauv tsev xws li kab txaj, kab laum thiab yoov.
Tam sim no, ib txoj kev tshawb fawb tshiab ntawm North Carolina State University uas tshuaj xyuas cov ntaub ntawv tshawb fawb txog kev tswj xyuas kab tsuag hauv tsev pom tau tias thaum cov kab hauv tsev ua rau cov tshuaj tua kab mob yoov tshaj cum, kev rov qab los ntawm kab txaj, kab laum thiab yoov mus rau hauv tsev yog ua rau pej xeem kev txhawj xeeb thiab kev txhawj xeeb. ua rau muaj kev txhawj xeeb. Feem ntau, tsis siv cov kev kho mob no ua rau muaj mob malaria ntau ntxiv.
Nyob rau hauv luv luv, lub txaj txaj thiab tshuaj tua kab kho tau zoo heev ntawm kev tiv thaiv yoov tshaj cum tom (thiab yog li ntawd malaria), tab sis tau pom ntau dua li ua rau muaj kab mob hauv tsev.
Chris Hayes, tus tub ntxhais kawm ntawm North Carolina State University thiab tus kws sau ntawv hais tias "Cov kab tshuaj tua kab no tsis yog tsim los tua cov kab tsuag hauv tsev zoo li kab kab, tab sis lawv zoo heev," said Chris Hayes, tus tub ntxhais kawm ntawm North Carolina State University thiab tus sau ntawm ib daim ntawv piav qhia txog kev ua haujlwm. . "Nws yog ib yam dab tsi uas tib neeg nyiam, tab sis cov tshuaj tua kab tsis zoo tiv thaiv kab tsuag hauv tsev."
Koby Schaal, tus kws tshaj lij ntawm Brandon Whitmire Distinguished xibfwb ntawm Entomology ntawm NC State thiab tus kws sau ntawv tau hais tias "Qhov teebmeem tshwm sim feem ntau yog teeb meem, tab sis qhov no lawv tau txais txiaj ntsig,"
"Tus nqi rau tib neeg tsis tas yuav txo qis ntawm malaria, tab sis kev tshem tawm lwm yam kab tsuag," Hayes ntxiv. "Tej zaum yuav muaj kev sib txuas ntawm kev siv cov nets no thiab cov tshuaj tua kab dav dav hauv cov kab hauv tsev no, tsawg kawg hauv Africa. txoj cai.”
Cov kws tshawb fawb ntxiv tias lwm yam xws li kev tshaib kev nqhis, kev ua tsov ua rog, kev faib hauv nroog-nyob deb nroog thiab kev txav ntawm cov pej xeem kuj tseem tuaj yeem ua rau muaj qhov tshwm sim malaria.
Txhawm rau sau qhov kev tshuaj xyuas, Hayes scoured cov ntaub ntawv tshawb fawb rau kev kawm txog cov kab tsuag hauv tsev xws li kab txaj, kab laum thiab fleas, nrog rau cov khoom ntawm malaria, txaj nets, tshuaj tua kab thiab tshuaj tua kab hauv tsev. Kev tshawb nrhiav tau txheeb xyuas ntau dua 1,200 kab lus, uas tom qab ua tiav cov txheej txheem tshuaj xyuas cov neeg sib tw tau nqaim mus rau 28 cov lus tshuaj xyuas cov phooj ywg uas ua tau raws li qhov xav tau.
Ib txoj kev tshawb fawb (kev tshawb fawb ntawm 1,000 tsev neeg hauv Botswana ua nyob rau hauv 2022) pom tias thaum 58% ntawm cov neeg txhawj xeeb tshaj plaws txog yoov tshaj cum hauv lawv lub tsev, ntau tshaj 40% muaj kev txhawj xeeb tshaj plaws txog kab laum thiab yoov.
Hayes tau hais tias tsab xov xwm tsis ntev los no tau tshaj tawm tom qab kev tshuaj xyuas hauv North Carolina pom tias tib neeg liam cov yoov tshaj cum rau qhov muaj cov kab cab.
"Qhov zoo tshaj plaws muaj ob txoj hauv kev," Schaal hais. "Ib qho yog siv ob txoj hauv kev: kev kho yoov tshaj cum thiab cais kev tswj kab hauv nroog uas tsom cov kab tsuag. Lwm qhov yog nrhiav cov cuab yeej tswj hwm malaria tshiab uas tseem tsom rau cov kab tsuag hauv tsev no. Piv txwv li, lub hauv paus ntawm lub txaj txaj tuaj yeem kho cov kab laum thiab lwm yam tshuaj muaj nyob hauv cov kab txaj.
"Yog tias koj ntxiv ib yam dab tsi rau koj lub txaj txaj uas tawm tsam cov kab tsuag, koj tuaj yeem txo qhov qias neeg nyob ib puag ncig cov nets."
