Approximately three-quarters of the Kenyan population is at risk for malaria. All four species of the malaria parasite that infect humans occur in Kenya. Plasmodium falciparum, which causes the most severe form of the disease, is the most common species and accounts for nearly all malaria infections in the country. The Kenyan government places a high priority on malaria control and tailors its malaria control efforts according to malaria risk to achieve maximum impact. Recent household surveys show improvements in coverage with malaria prevention and treatment measures and reductions in malaria parasitemia and illness.
Working in close coordination with the Kenya NMCP and county-level MOH officials, the PMI AIRS Project successfully implemented IRS in Kenya in 2017 after a lapse of five years. AIRS targeted structures in six sub-counties in Migori County (Awendo, Nyatike, Rongo, Suna East, Suna West and Uriri).
Following the successful 2017 IRS implementation, in 2018 the PMI AIRS Project expanded IRS to include Homa Bay County, more than doubling the scale of the previous year’s malaria control intervention. This IRS campaign included the six sub-counties in Migori County plus eight sub-counties in Homa Bay County. The PMI AIRS Project transitioned to the PMI VL Project in July 2018 and implemented its first campaign in 2019 in all 14 sub-counties covered in 2018 (Migori County: Awendo, Nyatike, Rongo, Suna East, Suna West and Uriri and Homa Bay County: Homa Bay Township, Rachuonyo East, Ruchuonyo South, Suba North, Ndhiwa, Rachuonyo North, Rangwe and Suba South)), with the exception of Mfangano Island due to inaccessibility and concerns over cost efficiency.
In 2019, under the PMI VectorLink Project, IRS was conducted in 14 sub-counties, targeting 465,862 structures using Actellic 300 CS and a small pilot of SumiShield from January 28 – March 16, 2019. A total of 507,777 structures were sprayed out of 551,689 structures found by spray operators in the targeted counties, accounting for a coverage rate of 92.0%.
In 2019, the project will work with NMCP, Migori and Homa Bay Counties ministries of health and environment to spray 384,639 targeted structures in two counties using Actellic 300CS. The project’s primary objective is to reach a minimum coverage of 85 percent of the structures found in each county by implementing high-quality IRS operations.
