Sero-Prevalence of Visceral Leishmaniasis and Associated Risk Factors among Febrile Patients Attending Metema Hospital, West Gondar Zone, North West Ethiopia.

Introduction: In Ethiopia, visceral leishmaniasis (VL) is a public health concern that has been spreading to new endemic foci in recent years. An estimated 3.2 million people are at risk of infection, with 3700-7400 new cases yearly. Thus, the study aimed to determine the prevalence of VL and associated risk factors among febrile patients attending Metema Hospital, North West Ethiopia.

Methods: A hospital-based cross-sectional study was conducted on 404 febrile patients attending Metema Hospital from February 2021 to June 2021. The test for VL was done using an immune-chromatographic test (RK39) according to the manufacturer's instructions (InBios International Inc., USA). An interviewer-administered, pretested questionnaire was used to collect data on risk factors associated with VL. Logistic regression and Chi-square assessed the association between VL and the associated risk factors.

Reults: The overall prevalence of visceral leishmaniasis was 18.8% (76/404), with a higher prevalence of VL in males, in the age category between 21 and 30, in study participants who completed elementary school, and in those who earned less than 500 birr monthly compared to their counterparts. Houses with thatched roofs (adjusted odd ratio (AOR) = 17.648, 95CI = 6.549,47.563), houses with mud walls (AOR = 2.538, 95% CI = 1.187-5.411), cattle ownership (AOR = 3.173, 95% CI = 1.286-7.826), dog ownership (AOR = 2,533, 95% CI = 1.256-5.111), presence of Acacia trees near houses (AOR = 1.975, 95% CI:1.004-3.886), presence of Balanites tree (AOR = 3.015, 95% CI = 1.610-5.992), and outdoor sleeping (AOR = 2.259, 95% CI: 1.107-14.607) were the predictors of VL in the present study.

Conclusions: In the study area, VL is still very common. Thus, preventing and controlling infection in the area is largely dependent on raising community awareness of VL prevention and control measures and implementing the necessary interventions on the determinants that have been identified.
