[Impact of building a dam on the transmission of malaria. Malaria survey conducted in southeast Mauritania].

In March during the dry season an investigation was conducted on the site of Foum Gleita dam in the Islamic Republic of Mauritania in order to study, one year after the filling of the dam, the epidemiological situation of local malaria at a clinico-parasitological, immunological and entomological level. No malarial transmission was observed in the 5th month of the dry season. So far, the damming of water has not led to the spread of anophelines which would have brought about malarial transmission not within the rainy season.
