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 2020, the PMI VectorLink project in Senegal resumed IRS activities in four health districts located in three regions, namely Koungheul (Kaffrine region), Koumpentoum and Makacolibatang (Tambacounda region) and Kedougou district (Kedougou region). In total, 136,417 structures were sprayed out of 137,932 structures found for a coverage level of 98.9%
Since January 2020, the PMI VectorLink project has been working collaboratively with NMCP to manage routine ITN distribution (storage, quantification, distribution of PMI-procured ITNs, supervision and reporting). As of October 2020, VectorLink has distributed 736,550 ITNs (14,731 bales) out of the 1,725,667 ITNs received in 2020 and 989,117 ITNs are remaining in stock.
The Goal of the PMI VectorLink Senegal Project (VectorLink Senegal) is to increase access to integrated malaria vector control interventions in Senegal.
The three specific objectives are:
- Objective 1: Reach a minimum coverage of 85% of the structures found in each target district by implementing high-quality IRS operations.
- Objective 2: Conduct entomological monitoring activities.
- Objective 3: Support the distribution of ITNs through routine channels.
VectorLink Senegal will carry work by implementing the following strategies:
- 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 promoting women’s meaningful and equitable participation across all 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).
- Subcontract with the Universite Cheikh Anta Diop (UCAD) for entomological monitoring activities.
- Work collaboratively with the NMCP, Regions and Districts to support the routine distribution of ITNs.
These objectives will be achieved by implementing the following activities:
- Conduct training with a focus on IRS supervision and spray techniques to improve the overall quality of spraying.
- Conduct IRS environmental compliance activities and inspections
- Conduct regular M&E of project activities to ensure alignment with set targets and objectives.
- Work collaboratively with the NMCP to coordinate community mobilization activities in collaboration with stakeholders to raise awareness of IRS and ITN interventions, promote acceptance and use, and to encourage beneficiary and stakeholder ownership.
- Conduct insecticide susceptibility and synergist tests nationwide and measure the resistance intensity, as required, for the main malaria vectors, Anopheles gambiae s.l. and An. funestus s.l.
- Monitor the density, species composition, behavior, blood meal sources, and Plasmodium sporozoite infection rates of malaria vectors in 32 sites across 17 districts in ten regions.
- Monitor the residual life of the sprayed insecticides using wall cone bioassays in the four IRS districts.
- Analyze IRS spray data, entomological and epidemiological data from Kedougou to assess impact of 2020 and 2021 IRS to determine whether spray will continue in 2022.
- Ensure reception and storage of all PMI procured ITNs for routine distribution.
- Distribute ITNs to each of the Medical Regions, as needed.
- Provide technical assistance to the central, regional, and district levels for the routine distribution of ITNs in order to build their capacity and improve their systems, including revision of the NMCP Routine Distribution Methodological Guidelines).
- Collaborate with other implementing partners in the four districts to complement each other’s work and avoid duplication of efforts in routine distribution of ITNs.
- 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.
