disease is endemic in most parts of rural Zambia, and associated complications are common. We conducted a cross-sectional study among 754 people in rural communities of Kaoma District, western Zambia to determine the burden of infection and associated morbidity. Parasitology and ultrasonography assessments were conducted on consenting participants. The overall prevalence of infection and geometric mean egg count (GMEC) were 42.4% (304) and 86.6 eggs per gram (95% confidence interval = 75.6–99.6), respectively. Prevalence was highest in the age group of 15–19 years old (adjusted prevalence ratio = 1.70, = 0.017). -related portal fibrosis was detected in 26% of the participants screened. Participants above 39 years old were 2.93 times more likely to have fibrosis than the 7–9 years old age group ( = 0.004). The study highlights the high burden of disease in this area and calls for immediate interventions to avert complications associated with the disease.
