Abstract
A mollusciciding campaign [to control Biomphalaria glabrata] was begun in Cul-de-Sac Valley, St. Lucia, West Indies, at the end of 1970, following several years of epidemiological studies in which transmission of S. mansoni was high in settlements on the valley floor but low in hillside settlements. Postcontrol (1971-73) findings in children, when compared with precontrol data and with data from an adjacent valley having a similar transmission pattern, show significant reductions in prevalence, incidence and intensity of infection.
