RésuméBackground: Malariometric information is needed to decide how to introduce malaria vaccines and evaluate their impact in sub-Saharan African countries. Methods: This cross-sectional study (NCT01954264) was conducted between October and November, 2013, corresponding to the high malaria transmission season, in four sites with Health and Demographic Surveillance Systems (DSS) [two sites with moderate-to-high malaria endemicity in Burkina Faso (Nouna and Sapone) and two sites with low malaria endemicity in Senegal (Keur Soce and Niakhar)]. Children (N = 2421) were randomly selected from the DSS lists of the study sites and were stratified into two age groups (6 months-4 years and 5-9 years). A blood sample was collected from each child to evaluate parasite prevalence of Plasmodium falciparum and other Plasmodium species and gametocyte density by microscopy, and rapid diagnosis test in the event of fever within 24 h. Case report forms were used to evaluate malaria control measures and other factors. Results: Plasmodium falciparum was identified in 707 (29.2%) children, with a higher prevalence in Burkina Faso than Senegal (57.5 vs 0.9% of children). In Burkina Faso, prevalence was 57.7% in Nouna and 41.9% in Sapone in the 6 months-4 years age group, and 75.4% in Nouna and 70.1% in Sapone in the 5-9 years age group. Infections with other Plasmodium species were rare and only detected in Burkina Faso. While mosquito nets were used by 88.6-97.0 and 64.7-80.2% of children in Burkina Faso and Senegal, other malaria control measures evaluated at individual level were uncommon. In Burkina Faso, exploratory analyses suggested that use of malaria treatment or any other medication within 14 days, and use of insecticide spray within 7 days decreased the prevalence of malaria infection; older age, rural residence, natural floor, grass/palm roof, and unavailability of electricity in the house were factors associated with increased malaria occurrence. Conclusions: Plasmodium falciparum infection prevalence in children younger than 10 years was 57.5% in Burkina Faso and 0.9% in Senegal, and variability was observed, among others, by age, study site and malaria control measures.
