This study explores how well the prevalence in that age group predicted \nthe overall prevalence in the community in data from stool examinations (Kato\u2013Katz method) from 180000 people in 3 \nmunicipalities in Brazil in 1984 and 1985. The median prevalence was higher in 1984, before community treatment was \nintroduced. There was a strong relationship between the prevalence among 7- to 14-year-olds and the overall prevalence \nin the community. We present sensitivities and positive predictive values for the use of prevalence in the indicator group \nto select communities for mass treatment as recommended by WHO. For a range of assumptions sensitivity and positive \npredictive value were never both above 80%. We suggest that the estimates of validity presented in this paper inform \nfuture evaluations of strategies for <jats:italic>S. mansoni<\/jats:italic> control.<\/jats:p>","DOI":"10.1017\/s0031182099006733","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T09:30:22Z","timestamp":1027762222000},"page":"507-512","source":"Crossref","is-referenced-by-count":5,"title":["Predicting the community prevalence of schistosomiasis mansoni from the prevalence among 7- to 14-year-olds"],"prefix":"10.1017","volume":"121","author":[{"given":"L.
