The adoption of new products for indoor residual spraying (IRS) is challenged by evidence gaps regarding their impact and cost-effectiveness. To provide evidence to address this gap, we present a retrospective, observational analysis of the epidemiological and entomological impact of IRS with different insecticides using routine indicators of malaria transmission.

Changes in ingredients have contributed to operational shifts in indoor residual spraying (IRS) in Ghana. These changes allowed for observational study to better describe the impact of IRS with a third generation IRS product with a focus on the impact of shifting ingredients and introducing IRS into previously unsprayed districts.

To supplement entomological analyses of a switch in indoor residual spraying (IRS) ingredients in Ghana, we conducted a preliminary, retrospective, observational analysis of the epidemiological impact of IRS. Results are triangulated with previous analyses to better understand the impact of IRS with next-generation products in a region with insecticide resistance.

In 2012, insecticide resistance promoted a switch in Ghana from pyrethroids to pirimiphos-methyl. We conducted a retrospective, observational analysis of the epidemiological impact of indoor residual spraying (IRS) operations in the Northern region of Ghana from 2014-2016, using routine epidemiological data comparing malaria incidence rates from IRS and non-IRS districts.

To best optimize available malaria funding, countries and programs have to make evidence-based decisions implementing malaria control interventions, including new vector control tools. This study aims to describe the malaria control decision-making landscape in Mali and Zambia and assess the facilitators and barriers that affect evidence generation and utilization.
