Malaria is endemic throughout Senegal and the entire population is at risk. Transmission occurs seasonally and is affected by rainfall and persistent flooding, especially in peri-urban areas. While the number of reported malaria cases has dropped in recent years, malaria is still a major cause of morbidity and mortality and a high priority for the government. Senegal has made significant progress against malaria and remains a leader in piloting and scaling up new recommendations and strategies to increase the reach and effectiveness of interventions. Striving toward malaria pre-elimination by 2018, malaria interventions in Senegal are targeted to the different transmission zones.

As part of an effort to scale up vector control (VC) interventions, the National Malaria Control Program (NMCP) has received support from the U.S. President’s Malaria Initiative (PMI) for Indoor Residual Spraying (IRS). In Senegal, IRS implementation began as a pilot in three health districts (Velingara, Nioro, and Richard-Toll) in 2007. Beginning in 2015, targeted IRS was implemented within districts where health posts reported high malaria incidence (> 15 cases/ 1000 inhabitants).

In 2018, the Senegal NMCP decided to discontinue PMI-funded IRS, but entomological monitoring will continue, particularly to evaluate monitor vector densities and sporozoite infection rates in areas following withdrawal of IRS. The Laboratory of Vector and Parasite Ecology (LEVP) of the Faculty of Science and Technology (FST) at the University Cheikh Anta Diop (UCAD) in Dakar, in collaboration with NMCP, has been implementing entomological monitoring activities in Senegal since 2007. Since 2015, UCAD continued the implementation of entomological monitoring activities as a subcontractor under the PMI Africa Indoor Residual Spraying Project. In 2018, the PMI VectorLink Project will be responsible for entomological monitoring in Senegal, and will continue to subcontract with UCAD for the implementation of project activities.
