Malaria is a leading public health challenge in Côte d’Ivoire. It accounts for about 43 percent of outpatient visits in health facilities. The malaria incidence in 2015 was 155.49 per 1000 in general population and 292 per 1000 among children under five years. To reduce malaria burden, the main malaria vector control method used in Côte d’Ivoire is the distribution and utilization of insecticide-treated nets (ITNs). ITN distribution is typically carried out through mass campaigns for universal coverage and routine distribution through antenatal visits for pregnant women and immunization visits for children under one year of age.
The National Malaria Strategic Plan 2016-2020 has selected Indoor Residual Spraying (IRS) as additional vector control method to reduce malaria morbidity and mortality. Entomological surveillance is a key component of malaria vector control as it provides information on vector species, including the spatial and temporal distribution, density, ecology, biting and resting behavior, and susceptibility to the insecticides used in public health interventions. The information collected guides decision making regarding selection and distribution of the malaria vector control tools. In Côte d’Ivoire, these data will also guide the National Malaria Control Program (NMCP) and stakeholders on insecticide selection, IRS programming, and insecticide resistance management.
The PMI VectorLink Project in Côte d’Ivoire will support entomological surveillance to collect more data on the susceptibility status of An. gambiae s.l. to the insecticides used in public health interventions and on malaria transmission; PMI VectorLink will also support the NMCP and the malaria vector control stakeholders in the selection of the districts and insecticide for IRS in the second year of the project. To prepare for the IRS campaign in 2019, PMI VectorLink will also conduct an environmental assessment in its first year of the project.
The project in collaboration with the NMCP and the entomology research centers will implement insecticide resistance testing in six sentinel districts, in conjunction with six other sentinel districts supported by the Global Fund. The entomological surveillance data from the 12 sentinel sites will provide information on the susceptibility status of An. gambiae s.l. across the four ecological zones in Côte d’Ivoire. In addition, comprehensive vector bionomics monitoring in four selected districts will provide information on vector distribution and infectivity and help to determine the best time to spray. Paired with information on malaria incidence, population density, and acceptability of IRS, the project will generate robust data to select the districts for IRS in the second round of spraying
