[Impact of curtains and blankets impregnated with permethrin on the malarial indicators and the number of malarial attacks per child in a village in an area hyperendemic for malaria on the Malian savannah (preliminary results of the first year study)].
From May 1989 to June 1990 an experimental study has been undertaken in two village's malarial hyperendemy of the Malian savannah. This study's objective was to test the effectiveness, on paludometric parameters and the openness of the population to the impregnated curtains and blankets, of permethrin as strategy of controlling malaria. The experimental village (Tiénéguébougou) and the control one (Kambila) are located in the same ecosystem and as at least 3 km any from each other. The impregnated curtains were installed in all the experimental village's houses and all the 216 residents have received impregnated blankets. The entomological, parasitical and clinical parameters were measured monthly from may 1989 to november 1989. The impregnated curtains were accepted by the population. However the impregnated blankets were little successful. Their impact on the entomological parameters is remarkable with a reduction of more than 98% of ma and the rate of entomological inoculation (REI) in the houses. The reduction of parasitical index is much less perceptible. The effect on the parasitical pressure was manifested by a highly significant difference of splenic index between the two villages (lower in the control village). The main vectors belong to complex: A. gambiae s.l. which rate of parity was not affected by the impregnated material. Very efficient against the harmfulness of in house hematophagic insects, the curtains impregnated by pyrethroids are not sufficient for interrupting the transmission of malaria. Actually, the study is continued for 2 years with a best evaluation of the malarial morbidity.
