Indoor residual surface treatments for malaria transmission control in areas with insecticide-resistant mosquito populations

Overview

"Preferred product characteristics” (PPCs) are key tools to incentivize and guide the development of urgently needed health products. The WHO categorization of existing and potential new vector control interventions is evolving from using the term “indoor residual spraying” (IRS) for the intervention class to the term “indoor residual surface treatment” (IRST). This PPC document was developed to stimulate further innovation in the area of IRST by articulating that WHO has identified a public health need for new interventions to treat indoor surfaces in order to provide additional options for the control of indoor biting/resting malaria vectors with a particular focus on providing alternative for insecticide resistance management.
