Kugwiritsa ntchitomankhwala ophera tizilombom'nyumba zingakhudze kwambiri chitukuko cha kukana matenda kunyamula udzudzu ndi kuchepetsa mphamvu ya mankhwala ophera tizilombo.
Akatswiri a sayansi ya zamoyo ku Liverpool School of Tropical Medicine asindikiza pepala mu The Lancet Americas Health yofotokoza za momwe amagwiritsira ntchito mankhwala ophera tizilombo m'mayiko 19 kumene matenda ofalitsidwa ndi tizilombo monga malungo ndi dengue ndi ofala.
Ngakhale kafukufuku wambiri awonetsa momwe njira zaumoyo wa anthu komanso kugwiritsa ntchito mankhwala ophera tizilombo kumathandizira kukulitsa kukana mankhwala ophera tizilombo, olemba lipotilo akuti kugwiritsa ntchito m'nyumba ndi zotsatira zake sikudziwika bwino. Izi ndizowona makamaka chifukwa chakuchulukirachulukira kwa matenda omwe amafalitsidwa ndi ma vector padziko lonse lapansi komanso chiwopsezo chomwe chimadzetsa thanzi la anthu.
Pepala lotsogozedwa ndi Dr Fabricio Martins likuyang'ana zotsatira za mankhwala ophera tizilombo m'nyumba pa chitukuko cha kukana kwa udzudzu wa Aedes aegypti, pogwiritsa ntchito Brazil monga chitsanzo. Iwo adapeza kuti kuchuluka kwa masinthidwe a KDR, komwe kumapangitsa kuti udzudzu wa Aedes aegypti ukhale wosagwirizana ndi mankhwala ophera tizilombo (omwe amagwiritsidwa ntchito kwambiri pazinthu zapakhomo komanso thanzi la anthu), pafupifupi kuwirikiza kawiri pazaka zisanu ndi chimodzi kachilombo ka Zika kamayambitsa mankhwala ophera tizilombo ku msika ku Brazil. Kafukufuku wa labotale anasonyeza kuti pafupifupi 100 peresenti ya udzudzu umene unapulumuka pangozi yakupha tizilombo ta m’nyumba unakhala ndi masinthidwe angapo a KDR, pamene udzudzuwo sunafe.
Kafukufukuyu adapezanso kuti kugwiritsa ntchito mankhwala ophera tizilombo m'nyumba ndikofala, ndipo pafupifupi 60% ya anthu okhala m'malo 19 omwe ali ndi kachilomboka amagwiritsa ntchito mankhwala ophera tizilombo kuti adziteteze.
Iwo ati kugwiritsa ntchito molakwika komanso kosavomerezeka koteroko kungachepetse mphamvu za zinthuzi komanso kukhudzanso njira zazikulu zaumoyo wa anthu monga kugwiritsa ntchito maukonde ophera tizirombo komanso kupopera mankhwala otsalira m'nyumba.
Kafukufuku wowonjezereka akufunika kuti awone zotsatira zachindunji ndi zosalunjika za mankhwala ophera tizilombo m'nyumba, kuopsa kwake ndi ubwino wake pa thanzi la anthu, ndi zotsatira za mapologalamu oletsa tizilombo toyambitsa matenda.
Olemba lipotilo akuwonetsa kuti opanga malamulo amakhazikitsa malangizo owonjezera pa kasamalidwe ka mankhwala ophera tizilombo m'nyumba kuti awonetsetse kuti mankhwalawa akugwiritsidwa ntchito moyenera komanso motetezeka.
Dr Martins, wofufuza kafukufuku wa vector biology, anati: "Ntchitoyi idakula kuchokera kuzinthu zomwe ndinasonkhanitsa pamene ndikugwira ntchito limodzi ndi anthu ku Brazil kuti ndidziwe chifukwa chake udzudzu wa Aedes ukukula, ngakhale m'madera omwe mapulogalamu a zaumoyo adasiya kugwiritsa ntchito pyrethroids.
"Gulu lathu likukulitsa kafukufukuyu m'maboma anayi kumpoto chakumadzulo kwa Brazil kuti amvetsetse momwe mankhwala ophera tizilombo a m'nyumba amayendetsera kusankha kwa majini okhudzana ndi pyrethroid resistance.
"Kafukufuku wamtsogolo wokhudzana ndi kukana pakati pa mankhwala ophera tizilombo m'nyumba ndi mankhwala azachipatala adzakhala ofunika kwambiri pakupanga zisankho zozikidwa ndi umboni komanso kupanga malangizo owongolera ma vector."
