The epidemiology of in the Lake Tana Basin (Ethiopia): Review with retrospective data analyses.

is one of the major waterborne diseases grouped underwater based Neglected Tropical Diseases in Africa. In Ethiopia, the Lake Tana Basin has favorable environment (temperature and water) for transmission. The prevalence of varies among regions based on environmental conditions and human water contact. Therefore, this review was conducted to identify hot spots districts and determine the prevailing prevalence in the Lake Tana Basin. Research articles published in English in the last 65 years were searched from Google scholar, PubMed, and Web of science. In addition, four-year data that were reported in health care facilities were extracted from health management information system in 61 districts of the Lake Tana Basin. In total, 43 research articles on that met the inclusion criteria and were published between 1957 and 2022. Over 98% of the articles were cross-sectional studies, while five articles addressed malacological studies. Among 61 districts, 19 (31%) were identified as hotspot districts for infection in the Lake Tana Basin. prevalence and the abundance of its host snail showed spatial and seasonal variations. On average 2000 school children/year attended health care facilities for infection. Swimming habits [adjusted odds ratio (AOR) = 3.2, p = 0.030], irrigation practice (AOR = 3:09, p ≤ 0.001), fishing (AOR = 2:43, p = 0.005) and being male (AOR = 1.74, p = 0.002) were risk factors for contributing to infection. This study showed the spatial and seasonal variations of prevalence and its endemicity in the hottest lowland areas of the Lake Tana Basin. The research articles on had poor geographical coverage. Malacological studies on water bodies, assessments on knowledge and attitude in the community towards transmission are areas of future studies.
