The prevalence and morbidity of Schistosoma japonicum infection on 2 islands (large, Qingshan; small, Nianjiashan) in the Dongting lake region, Hunan Province, China, were studied in 1996. Overall, 1909 individuals representing 72.2% of the local population were examined. Stool examinations revealed that the prevalence on the large and small islands was 14.6 and 23.7%, respectively. Two distinct peaks of prevalence were observed at age groups 25-34 and 45-54 years on the large island.
