This monsoon plays an important role while provoking hydrological consequences that result from climate variability over time and space. Such consequences may be droughts or floods with harsh consequences for the socioeconomic activities of the urban population and the environment. For example, the Sahelian drought of the 1970s forced the urban populations to relocate to former backwaters, ponds and mud flats located within Saint-Louis (Senegal). However, better levels of rainfall in the late 1990s subjected the urban population to severe flooding and precarious environmental conditions. This situation is due to the poor and inadequate water network systems which in most cases are old and obsolete. Hence, the poor environmental conditions and stagnant water encourage the breeding of several species of mosquitoe. Among the species, Anopheles and Aedes are the most dangerous because of the transmission of malaria and yellow fever. It is thus important to investigate and model the population’s vulnerability to infectious diseases as a result of current climate variation and its consequences. This work entails the integration of spatial and non-spatial data within the technological framework of a Geographical Information System (GIS), in order to assess the health impacts due to climatic fluctuation. The results show that there is a relationship between periods of flooding, cases of disease and mosquitoes.
