Randomized trial evaluated schistosomiasis prevalence in Hunan Province, indicating reduced infections in humans and bovines.

This research aimed to evaluate the current epidemiological status of schistosomiasis japonica in Hunan Province, China.
Conducted a sampling survey in 1995 involving 45,590 humans and 3,726 domestic animals across 52 villages.
Examined subjects for schistosoma japonicum using parasitological and serological tests.
Compared results to baseline data from 1989 to assess changes in infection prevalence.
Overall human prevalence of S. japonicum was 7.81% in uncontrolled endemic villages, with 45.65% reduction since 1989.
Geometric mean intensity of infection was 17.71 eggs per gram among infected individuals.
Bovine prevalence was 9.63% in endemic areas, showing over 60% reduction during the sampling period.

Dongbao et al. (1999) studied this question.
