Interventions Milestones in Senegal
Controlling Biting Mosquitos
The mass distribution of long-lasting insecticide-treated nets (LLINs) has been a main driver of Senegal's reduction in malaria transmission. The first mass distribution campaign of LLINs in Senegal occurred in 2009 and targeted every child under the age of five. As of 2010, mass distribution campaigns, conducted on average every two years, aim at universal coverage—one net for each sleeping space across the country.
Net distribution across Senegal increased from 1.3 million nets in 2008 to 3.4 million in 2013 and 3.8 million in 2014. Household surveys show that this increase in distribution is mirrored in coverage and usage data. While LLIN distribution is the backbone of vector control interventions in Senegal, innovative methods of controlling biting mosquitoes are on the horizon.

Delivering high-quality case management
Case management refers to the prompt diagnosis and treatment of malaria infections to reduce the likelihood of progression to severe disease and death. Additionally, timely case management may reduce transmission by markedly shortening the duration of infection, thereby decreasing the chance of parasite transmission from humans to mosquitoes.
Both artemisinin-based combination therapy (ACT) and rapid diagnostic tests (RDTs) are provided free at the point of care to all patients (with all health services provided free to children under five years of age). Starting in 2008, RDTs and ACT have been widely available at the community level through the PECADOM scheme—a community-based model of care. This involves the recruitment of a DSDOM—an individual chosen by the community who is trained in malaria case management. This individual provides care to all patients within the village, and is trained to refer those with negative RDT results (or serious illness) to local health services. In 2012, a pilot program in five districts expanded PECADOM to integrate treatment of diarrhea and acute respiratory illness (ARI) to reduce childhood mortality. The program has now been rolled out nationwide.
Decreasing risk among vulnerable populations
In addition to case management, antimalarial drugs are used to reduce the disease burden in vulnerable populations—including pregnant women and children—in high-transmission areas.
In order to prevent malaria in pregnancy, Senegal introduced intermittent preventive treatment in pregnancy (IPTp) in 2003 with sulfadoxine-pyrimethamine (SP) given free of charge across the country.
Trials of the impact of seasonal malaria chemoprevention (SMC) demonstrated a significant decrease in malaria incidence and mortality in children up to ten years of age. Since adopting SMC in 2012, Senegal has employed a community health platform for the distribution of sulfadoxine-pyrimethamine + amodiaquine (SP-AQ), using a door-to-door approach targeting children up to ten years old.
