[Identification of high risks regions of schistosomiasis in Côte d'lvoire].

Regional and national epidemiological data being not available for coherent and efficient control strategies, the identification of high risk zones of schistosomiasis was set up in 5 regions of Côte d'lvoire in April 1999. The inquiry was conducted by questionnaire in 1291 primary schools including 119624 pupils. After less than 2 months, the results revealed blood in urines and in stools in respectively 22035 (18.6%) and 27555 (23.3%) pupils. Out of 1089 (99.8%) schools at risk of schistosomae, 358 (32.9%) are high risk schools. They are to be found especially in the Agnéby (30.8%) and the Marahoué (19.9%) regions identified as high risk areas where actions of control are then important to implement. They are followed by the Lakes regions (15%), the Middle-Comoé (12.6%) and Southern-Comoé (8.9%). These results should help to develop the schistosomiasis control in Côte d'lvoire.
