Acceptance of IRS was influenced by diverse operational and contextual factors.
indoor residual spraying (IRS)
The core vector control measures, long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS), reduce the risk of malaria infection by targeting indoor biting mosquitoes.
IRS coverage from the 2015 spray season benefited from the use of spatial aids based upon satellite enumeration.
The preliminary data from this pilot study showed that IRS with the CS formulation of pirimiphos-methyl is likely very effective in reducing malaria transmission risk.
From 2012 to 2015, the annual IRS campaigns in Ségou are associated with several hundred thousand fewer cases of malaria.
The level of willingness to take up IRS was low (79%) compared to the targeted 85%.
This study demonstrates that IRS application did have a significant impact on entomological indicators of malaria transmission in the IRS project districts of Northern Ghana.
There was sustained control of malaria incidence during IRS implementation.
Long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) have contributed substantially to reductions in the burden of malaria in the past 15 years.
A rapid reduction in malaria incidence was observed in Tororo District following the introduction of IRS in addition to LLINs.
