Approche geographique dans la lutte contre le paludisme dans la region des Hautes Terres Centrales a Madagascar

ABSTRACT

"Geographic Information System as a supplementary tool in malaria control in Madagascar"" Following the severe malaria outbreak in the central highlands in Madagascarin 1986; a vector control program by use DDT pm 75 house-spraying has been implemented to operate in areas located at altitudes between 1000 and 1500 m. Early treatment with chloroquine has also been incorporated in the control program. To detect areas at particular high risk for malaria outbreak the Geographic Information System (GIS) has been applied and tested. The study has shown that the system can be used in malaria surveillance in order to identify areas in which an intense distribution of Anopheles funestus can be anticipated and; hence; targeted in spraying campaigns. The system may also be used to monitor changes in anti-malarial drug resistance; in addition; to control of other vector-born diseases."
