The efficacy of permethrin impregnated curtains as a malaria control measure was evaluated in a rice field are nearby Ouagadougou (BF). Two groups of children aged 1-5 years matched for age, sex and malaria exposure, were followed through the rainy season of 1987 for illness and febrile episodes. One group of 118 children lived in houses protected with impregnated curtains, the other in houses without curtains. All children were examined for parasitaemia spleen index packed cell volume (PCV) and antisporozoites antibodies at the beginning and the end of the rainy season. During rainy season no difference could be found in the number of clinical episode between the two groups. A reduction in the prevalence of splenomegaly and parasitaemia and an increase in the PCV was observed during the dry season. It is suggested that curtains may have a protective effect during the period of moderate transmission.

The impact of permethrin-impregnated curtains on the incidence of malaria episodes, parasitaemia and splenomegaly was assessed during a 22 month period in 2 groups of children aged 0.5-6 years. One group lived in houses where permethrin-impregnated curtains had been installed, the other group lived in houses without curtains. A significant reduction of incidence of malaria episodes, mean parasite density, parasite prevalence and splenomegaly was consistently observed in the intervention group towards the end of the period of moderate transmission, whereas no clear-cut impact could be demonstrated during the high transmission period. The influence of malaria pressure and community utilization on the protective efficiency of curtains is discussed. Because of their acceptability and the ease of reimpregnation, curtains proved to be a suitable technique for integration into primary health care.

The degree of utilisation of permethrin-impregnated curtains was assessed in a rural community near Ouagadougou, Burkina Faso. Results showed that in the first half of the night, until 11-11.30 p.m., curtains were only partially used by the community. Indeed by this time around 50% of houses had doors well protected by curtains and, over 35% of the community, children and adults, were staying outside. A very marked pattern of this behavior was found, wrong utilisation of curtains being higher in the warm season and lower in the cold season. On the one hand, this situation decreased the potential action of curtains as a barrier to avoid mosquito-man contact and, on the other hand, facilitated the exposure of community to the risk of outdoor infection. These findings may explain the variable level of efficacy showed by curtains in the prevention of malaria morbidity, which seems to be higher in the period between January and February, the winter season in Burkina Faso. The possible application of impregnated curtains as a community-based vector control method is discussed.
