ABSTRACT: Malaria, a febrile human disease transmitted by
female anopheles whose ecology is linked to water, is a major public
health problem in Côte d’Ivoire, more precisely in the Marahoué region
located in the southwest of the country. In order to effectively control this
disease, it is necessary to understand the etiology and the diffusion pattern
of the vectors. This justifies this study, which proposes to determine the
areas at risk of malaria transmission in order to carry out an effective fight
against this disease in this region of Côte d’Ivoire. To achieve this, a combined approach of geographic information
systems and multicriteria analysis was adopted. The analysis reveals that the
south and northwest of the Marahoué region present a high risk for malaria
transmission. This risk is linked to
indicators such as climatic factors that cover 48.36% of the study area,
environmental factors such as vegetation cover (NDVI), soil moisture (NDWI),
altitude, hydrography (water point) and population that covers 55.29% of the
area and land use. Also, the results indicated that 50.70% of the region has
favorable conditions for malaria transmission. Overall, climatic and
environmental indicators are the risk factors associated with the resurgence of
malaria.
