The objectives of the study were to assess the IVM strategy for malaria control, to assess the impact of IRS strategy and to identify gaps for future programming and scale-up exercise to other LGAs.
Monthly data from reporting health facilities in Ikorodu LGA were reviewed from 12 months preceding the implementation of IRS (April 2009-March 2010) and 12 months following the implementation (April 2010- March 2010). Data on new malaria cases treated for each month was collated. Data was summarised using means and paired ‘t’test to explore the differences in malaria incidence in pre IRS and post IRS periods . Level of significance was set at p<0.05.
The mean incidence of malaria post IRS (3.94 cases/1,000 population/month, SD 1.59) was significantly (t(11) =2.31, p=0.04) less than the mean incidence pre IRS( 5.76 cases /1000 population/month, S.D 2.49) with a mean difference of 1.82 (95%CI, 0.84,3.56).
IRS has achieved its goal of reducing morbidities from malaria in Ikorodu LGA. IRS is still continuing in 6 LGAs (Ojo, Ikorodu, Amuwo/Odofin, Kosofe, Badagry, and Ibeju/Lekki) to prevent resurgence and efforts are being intensified to scale up the IRS exercise to other LGAs within the State.
Learning Objectives: To share knowledge on assessment of the Integrated Vector Management strategy for malaria control. To assess the impact of Indoor Residual Spraying strategy and to identify gaps for future programming and scale-up exercise to other LGAs.
