Abstract
community-based, cross-sectional study design was adopted using 501 consented children under the
age of 14 years from 200 households. Mathematical model for determining the relationship between
malaria prevalence (MP) and features of the household surroundings was designed using multiple regression
models. Children age was 75.0 ± 45.5 months (range = 3–168 months). MP was 29.9/100, Most of the
houses 99.0% had open drainage immediately around their surrounding, 7.1% of the drainages were flowing
while 91.9% were stagnant. Solid Wastes in Drains (SWD), Stagnation of Wastewater in Drains
(STWD), Presence of Open Drains (POD), and Presence of Weeds (POW) significantly predicted MP while
reduction in MP after a 12-months intervention was 14.4%. Features of the household surroundings contributed
more to MP and covered drainage system could reduce the burden of malaria through free flow
of wastewater. This engineering solution could be encouraged in communities with high MP.
