title: [Schistosomiasis mansoni: dynamics of transmission].
abstract: The following remarks were addressed at the round table that discussed the alternative approaches to schistosomiasis control. The address begins with a short analysis of the progressive spread of the area of distribution of the disease, and of the difficulties faced by those in charge of control programs, conventional or otherwise. A model was sketched, taking into consideration the distinct classes of factors involved in the dynamics of transmission: biological, immunological, ecological, socio-cultural, and economical. The true significance and pertinence of such a model was analysed, and the relevant questions that must be answered before a true representative model can be constructed, were listed.
