Maximizing the Impact of Vector Control with Entomological Surveillance
As malaria programs face severe funding constraints, entomological surveillance is increasingly at risk of being reduced or eliminated, making it critical to focus limited resources on the data that are most essential for vector control decisions. Developed by the UCSF’s Malaria Elimination Initiative (MEI) and the Clinton Health Access Initiative (CHAI), this practitioner’s guide draws on engagement with six national malaria programs through a March 2026 workshop in Nairobi, as well as key informant interviews with subject matter experts conducted between November 2025 and May 2026. The guide offers practical recommendations for “right-sizing” entomological surveillance: link surveillance investments directly to programmatic decisions, adopt more cost-efficient sampling strategies, expand community-based and technology-enabled data collection, and integrate surveillance infrastructure and resources across diseases and borders. The overarching goal is to preserve the surveillance that matters most for the decisions malaria programs need to make.
