Little is known about transmission and seasonal and spatial patterns of malaria in urban context in the Sahel. The rapid urban growth and the spatial heterogeneity of African cities make urban malaria to a central issue in future. To overcome these gaps the research presents the spatial and seasonal patterns of malaria epidemiology in the urban setting of N’Djamena, Chad. The study analyses the frequency and seasonality of malaria, looks at the quality of malaria treatment of primary care providers, maps zones of high transmission and defines households’ responses to the disease. The results show that malaria transmission is seasonally, but not spatially heterogeneous: malaria prevalence rates are not higher in peri-urban areas. It also brings evidence to the fact that diagnosis strategies should be revisited in order to improve treatment and reduce economic costs. The author further recommends a partial re-allocation of available human and other resources from well equipped, central areas to under equipped, peripheral urban areas. These are important issues in the elaboration of locally adapted malaria control strategies in Sahelian urban setting.
