High mobility, poor conditions and limited healthcare access heighten the risk of visceral leishmaniasis (VL) among refugees. Though, data on infection prevalence is remains limited. This study aims to determine the prevalence of <jats:italic>Leishmania<\/jats:italic> infection in refugee camps in Benishangul Gumuz and Gambella regions to improve VL detection and guide effective control strategies in humanitarian settings.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec025\">\n<jats:title>Methods<\/jats:title>\n<jats:p>A cross-sectional study was conducted from May to August 2023 in four refugee camps to determine <jats:italic>Leishmania<\/jats:italic> infection using DAT and rtPCR on blood samples. Sociodemographic and clinical data were collected using structured questionnaires. Ethical approval was granted, and informed consent was obtained. Data were analyzed using SPSS v23, with associations assessed using logistic regression and Chi-square tests at a 0.05 significance level. Continuous variables summarized by median and interquartile range (IQR).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec026\">\n<jats:title>Result<\/jats:title>\n<jats:p>The study included 1,223 participants (440 from Tsore camp and 220 from Sherkole in Benishangul Gumuz Region; 288 from Kule camp and 275 from Terkidi in Gambella Region), most of whom were from South Sudan (66.7%) and the majority were females (56.5%). 17.8% of the participants reported fever, with no spleen or liver enlargement and 0.2% lymph node swelling. Real-time PCR positivity was significantly higher in Tsore (14.6%, \u03c7\u00b2\u2009=\u200921.4, p\u2009&lt;\u20090.001), no significant difference in DAT positivity was observed across refugee camps (\u03c7\u00b2\u2009=\u20096.6, p\u2009=\u20090.084). <jats:italic>Leishmania<\/jats:italic> DAT positivity rates were 6.0%, 4.6% and 4.7% in those with fever, chills and headache, respectively. <jats:italic>Leishmania<\/jats:italic> kDNA based rtPCR positivity rate were 11.7%, 8.8%, 7.3% and 6.2% in those with fever, chills, headache and weakness, respectively. Participants from Benishangul Gumuz region [AOR: 3.67 (95%CI: 1.57-8.59); p\u2009=\u20090.003]; South Sudanese [AOR: 2.87 (95%CI: 1.26-6.50); p\u2009=\u20090.012 and those with fever [AOR: 2.08 (95%CI: 1.01-4.28); p\u2009=\u20090.047] had a higher odds of DAT positivity. On the other hand, lower rtPCR positivity rates were seen in the Sherkole refugee camp compared to Tsore camps in Benishangul Gumuz region [AOR: 0.19 (95%CI: 0.08-0.45); p\u2009&lt;\u20090.0001].<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec027\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p><jats:italic>Leishmania<\/jats:italic> infection was prevalent in refugee camps in Gambella and Benishangul Gumuz regions.
