Abstract:
Background. Malaria remains a serious public health problem, particularly in resource scarce areas of the world. 'e number of
malaria cases has dropped remarkably in Ethiopia over the last decade, and e,orts to eliminate the disease are underway.
Asymptomatic infections may pose signi-cant challenges to the elimination program. 'e essence of this study was to assess the
prevalence of asymptomatic Plasmodium infection and the associated factors among communities of the selected districts in the
Ka,a zone. Materials and Methods. April to May and September to October 2021, were the two seasons in which the communitybased
cross-sectional survey was conducted. Capillary blood from a -nger prick was examined by light microscopy (LM) and
screened using rapid diagnostic tests (RDTs). 'e participants’ sociodemographic characteristics and malaria prevention measures
were collected using a pretested semistructured questionnaire. Data entry and analyses were carried out using EpiData and SPSS
version 25.0. Logistic regression (bivariate and multivariable) analyses were carried out to assess the possible associations between
the dependent variable and the associated factors. Results. 566 study participants were involved in the two cross-sectional surveys,
including 234 male and 332 female subjects with a mean age of 18.486 (SD ± 15.167). 'irty-eight blood samples (6.7%) were
found to be positive for Plasmodium species tested by both LM and RDT. Last night’s use of long-lasting insecticidal net (LLIN)
(AOR � 2.448, 95% CI: 1.009 5.938, p � 0.048), presence of eave (AOR � 4.144, 95% CI: 1.049–16.363, p � 0.043), and house
sprayed in the last year (AOR � 5.206, 95% CI: 2.176–12.455, p < 0.001) were among factors that showed signi-cant association
with asymptomatic Plasmodium infection. Conclusion. 'e asymptomatic Plasmodium infection prevalence recorded in the study
area was low. Last night’s LLIN usage, the presence of an eave, a house sprayed in the last year, and the presence of stagnant water
near the home of the study participants were among the factors associated with an increased risk of catching the disease.
