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.

Implementation of indoor residual spraying for vector control is shifting with the emergence of insecticide resistance. Cross-analyzing vector control interventions across countries, partners, and strategies is hampered by measurement methods and indicator definitions. Small changes in definitions can impact the interpretation and analysis of the effectiveness of vector control programs.

There is a lack of evidence on impact and cost of new insecticides used for indoor residual spraying (IRS) to protect against malaria. This study analyzed data collected in Southern Province, Zambia to retrospectively evaluate the effectiveness of next-generation IRS, such as Actellic, on malaria incidence and prevalence in Zambia.
