Contribution of Seasonal Malaria Chemoprevention (SMC) to the Reduction of Malaria Burden in Children Under 5 Years of Age in the Sud-Ouest Region, Burkina Faso

Moumouni Bonkoungou, Ousmane Badolo, Mathurin Bonzi, Youssouf Sawadogo, Andre Kone, Thierry Ouedraogo, Gauthier Tougri, Mathurin Dodo, Edward Kenyi, Gladys Tetteh, and William Brieger working with the US PMI Impact Malaria project implemented Seasonal Malaria Chemoprevention (SMC) in collaboration with the National Malaria Control Program (NMCP) of Burkina Faso in 3 regions. Their findings are seen below and are presented at the Annual Meeting of the American Society of Tropical Medicine and Hygiene in Seattle.

According to health statistics for 2020, in Burkina Faso, malaria accounts for 40% of medical consultations and 27% of deaths. Children under 5 years of age account for 72% of malaria deaths. 

In 2021, the SMC consists of the administration of three days of monthly treatments of amodiaquine plus sulfadoxine-pyrimethamine to all eligible children (3-59 months of age) during the high malaria transmission season (June to October). The objective is to maintain therapeutic concentrations of these antimalarials during the period of high transmission. 

In 2021, 19 of 70 health districts (27%) were supported by the project to implement SMC with more than 838,000 children under 5 years treated, including 180,000 from the Sud-Ouest region (Dano, Batie, Kampti, Gaoua, and Diebougou health districts). In this region of high rainfall, the number of severe malaria cases in children under 5 years decreased from 17,760 in 2017 (before SMC) to 14,609 in 2021 with SMC after 4 years of SMC implementation, i.e., a reduction of 17%. 

The number of malaria deaths also decreased from 133 in 2017 (before SMC) to 118 in 2021, a reduction of 11%. Kampti health district recorded the highest reduction of deaths of 78% [33 to 7 deaths] between 2017 and 2021 and Dano district had a reduction in severe malaria cases by 28% between 2017 and 2021. 

The main challenges with SMC include a delay in referral of fever cases by community distributors to health facilities during the campaign, management of vomiting during the 2nd or 3rd dose, and failure to retain the treatment cards by the parents. Seasonal Malaria Chemoprevention is a proven intervention and appears to be an important

component of the malaria prevention strategy in Burkina Faso but consideration should be given to address ongoing implementation challenges.
