Abstract
The disease schistosomiasis is commonly caused by two major species, namely, S haematobium and S mansoni in Ethiopia. The primary objective of the study was to determine the burden of the disease and associated risk factors of intestinal schistosomiasis in and around Delo-Mena district from March to June,2022. The study included an age group of students ranging from 5-14 years with a mean participant age of 9.25 years old. A school-based quantitative cross-sectional study was conducted among two selected primary/elementary schools after completing the interview through a prepared questioner. Parallelly based on the interview, collected stool samples from each individual were processed at the field and facility using single Kato-Katz and Ritchie’s concentration techniques for the presence and absence of S mansoni eggs as well as infection burden or intensity. A total of n = 250 school children were included during the study with a composition of 37.6% female and 62.4% male. The overall prevalence of S mansoni infection was 39.2%, n = 98 (moderate). Among compared determinant risk factors and sociodemographic characteristics, sex, residence, sources of water, and swimming habit had shown a strong statistical association, AOR = 3.11 (1.75,5.51), 0.26 (0.15,0.45), 0.37 (0.21,0.63) and 16.92 (8.11,35.29), respectively p < 0.000. The intensity of S mansoni infection was found to be heavier in male students n = 28 (11.2%) when compared to females, p < 0.000. Similarly, students engaged in swimming were more exposed to heavier infection than non-swimmers, n = 31 (13.6%) and n = 3 (1.2%), respectively, with AOR = 16.92(8.11,35.29), p < 0.000. Despite students who had a swimming habit, frequent swimming was also strongly related with heavier S mansoni infection with n = 28(11.2%) and n = 3(1.2%), respectively, when students swim always and sometimes. The study concluded with the recommendation of an integrated control strategies due to the resulted burden of infection which was lined to moderate level.
