Abstract:
Background: Malaria remains the first important public health concernsacross the globe.The
highest morbidity and mortality burden is in sub Saharan African countries. Little is known
about indoor residual spraying (IRS) in areas with intense malaria transmission sub-Saharan
Africa including Ethiopia.
Objective: This study assessedprevalence of malaria and associated factors among Indoor
Residual Sprayed versus Non Sprayed households in Gomboraworeda , Hadiya zone ,South
Ethiopia,March 2017
Method: we conducted community based comparative Cross sectional study among IRS
households verses non sprayed households in Gombora woreda.Weselected 462 participants
from IRS and 462from non IRS kebeles using stratified multistage sampling method.We used
Epidata for data entry and SPSS ver.21for analysis.Bivaraite and multivariate analysis was done
to examine the relationship between malaria and no malaria with IRS status.
Result: Four hundred twenty three participants from sprayed households and 423 from non
sprayed total of 846 individuals were participated. In this study participants from non sprayed
households more malaria AOR 1.798(95%CI 1.052-3.07)than participants from sprayed
households. The prevalence of malaria in sprayed households29(6.63%) lower than non sprayed
households 42(9.9%) from all participants.Those individuals living in one kilometer to stagnant
water source were more affected 1.873(95% CI 1.554-7.183)times than those far away.Children
age ≤ 5 years weremore affected than age ≥ 15 years with AOR 3.384(1.554-7.366).Students that
read and write only were more likely infected by malaria AOR 2.103(1.046-4.229) than grade 9
and above students.
Conclusion:Malaria infection among sprayed households was lower than non sprayed
households. Therefore strengthening IRS is an important measure to eliminate malaria from
Gombora woreda as well as Hadiya zone SNNPR Ethiopia.
