RESUMO
Objective To evaluate the effect on schistosomiasis control by implementing the synthetic measures with emphasis on infection source control.Methods Ten higher endemic villages in 10 counties were chosen to implement the measures of " replacing cattle with machines", "rearing domestic animals in pens", "safely treating night-soil or building methane-generating pits".In these villages, all cattle should be eliminated, other livestock be reared in pens, and all households be supplied with sanitary lavatories that could safely treat night-soil, or with methane-generating pits, and safe water. Results After 1 year of implementing the project, the number of cattle, sheep, pigs and dogs in 10 villages reduced by 92.7%,70.8%,14.3% and 20.2%, respectively, 76.0% of households had sanitary lavatories or methane-generating pits, 75.9% of households had safe water supply, all the remaining pigs were reared in pens, and the schistosome infection rate of residents reduced by 75.8%, the infection rate of cattle reduced by 79.8%, the density of infected snails reduced by 75.0% and the infection rate of snails reduced by 60.0%, respectively. Conclusion The synthetic measures with emphasis on infection source control are effective in schistosomiasis control.
