ABSTRACT

OBJECTIVE: To evaluate the contribution of poses screen pre-impregnated (PSP) installed at openings and eaves of dwellings in the reduction of malaria transmission in the commune of Aguégués in Bénin. METHODS: The PSP were manufactured from preimpregnated Olyset Net. They were installed at windows, eaves and doors of 70 dwellings. 320 children aged 6-59 months were treated and 311 children were recruited in the control zone. Variables measured are plasmodic index (IP), gametocyte index, parasite density (PD), fever, hemoglobin, anemia. RESULTS: The global IP was 16.62% with PSP and 72.20% without PSP. Gametocyte index did not differ significantly between the treated zone (27.8) and the control zone (29.1). The total geometric mean of DP was 309 in the treated zone and 600 in the control zone. Hemoglobin level is 8.7 in the control zone and 9.5 in the treated zone. We noted a predominance of anemia in the control zone compared to the treated zone. CONCLUSIONS: The PSP have contributed to a significant reduction in morbidity in the commune of Aguégués.
