An epidemiological study of the Schistosoma japonicum reinfection rate in 6 endemic villages in the Poyang lake region, Jiangxi, China, was carried out. The results showed that there was a close correlation between the reinfection rate after chemotherapy and the pre-treatment prevalence of infection. In a hyperendemic village, the annual reinfection rate remained above 30%. In a second hyperendemic village with environmental modifications, the annual reinfection rate was significantly reduced.
