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 the 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 2020, the PMI VectorLink Senegal project will work with the local partners to spray 134,883 targeted structures in four districts using Fludora® Fusion and SumiShield® 50WG. The project’s goal is to reach a minimum coverage of 85 percent of the structures found in each district by implementing high-quality IRS operations.
In addition to spraying, the project will carry work towards the following objectives:
- Build capacity at the national, regional, district, and local levels to manage IRS operations, including planning, spraying, resource allocation, and monitoring and evaluation (M&E).
- Mainstream gender equality and female empowerment by ensuring women’s participation in different project activities.
- Strengthen the IRS logistics and warehousing system through enhanced training and supervision.
- Ensure safe and correct insecticide application, thus minimizing human and environmental exposure to IRS insecticides, in compliance with the Pesticide Evaluation Report and Safer Use Action Plan and Supplemental Environmental Assessment (SEA).
- Support the routine distribution of ITNs at the national level and Piperonyl Butoxide (PBO) ITNs distribution in the district of Tambacounda.
These objectives will be achieved by implementing the following activities:
- Prepare an exit strategy for the end of the project in 2022 in collaboration with key stakeholders and other implementing partners working on malaria prevention and control.
- Conduct training with a focus on IRS supervision and spray techniques to improve the overall quality of spraying.
- Conduct regular M&E of project activities to ensure alignment with set targets and objectives.
- Using findings from the Year Two logistics assessment in the spray districts, arrange all procurement, shipping, delivery, and storage of IRS commodities.
- Coordinate community mobilization activities in collaboration with stakeholders to raise awareness of IRS and to encourage beneficiary and stakeholder ownership.
- Collaborate with other implementing partners in the four districts to complement each other’s work and ensure no duplication of efforts.
- Prepare a new 2020 – 2025 nationwide supplemental environmental assessment (SEA).
- Conduct insecticide susceptibility and synergist tests nationwide and measure the resistance intensity, as required, for the main malaria vectors, Anopheles gambiael. and An. funestus s.l.
- Monitor the density, species composition, behavior, blood meal sources, and Plasmodium sporozoite infection rates of malaria vectors in the selected districts.
- Monitor the residual life of the sprayed insecticides using wall cone bioassays in the four IRS districts.
- Distribute ITNs to each of the Medical Regions as needed.
- Provide technical assistance to the central, regional, and district-level for the routine distribution of ITNs.
- Conduct distribution of Piperonyl Butoxide (PBO) ITNs in 60 villages in the district of Tambacounda
