To evaluate the prevalence, intensity, and clinical morbidity of Schistosomiasis japonica in an endemic rural region prior to the launch of targeted control efforts.
Surveyed 96% of the available population aged 2 to 65 years across two rural brigades (Brigade A, N=778; Brigade B, N=1532) in Gui-chi County, Anhui Province, China.
Conducted quantitative fecal examinations to measure egg output and performed standardized medical histories and physical examinations.
Infection prevalence reached 26.3% in Brigade A and 14.4% in Brigade B, with approximately 50% of the overall population having a history of prior treatment.
Increased weakness was limited to individuals with the highest egg counts, and hepatomegaly was slightly elevated in moderate and heavy infections.
Splenomegaly was rare and unrelated to intensity, while abdominal pain, stool consistency, and fecal occult blood showed no association with infection status.
