Evaluation of community-based systems for the surveillance of day three-positive Plasmodium falciparum cases in Western Cambodia

摘要

BackgroundDelayed clearance of Plasmodium falciparum parasites is used as an operational indicator of potential artemisinin resistance. Effective community-based systems to detect P. falciparum cases remaining positive 72 hours after initiating treatment would be valuable for guiding case follow-up in areas of known resistance risk and for detecting areas of emerging resistance.
