Although considerable progress has been made in malaria control in Cambodia over the past decade, the disease remains a major concern for the international community, the Ministry of Health, and the Cambodian people. This is primarily due to the confirmed spread of resistance to artemisinin drugs, the principal component of the first-line malaria treatments that are currently used worldwide. In Cambodia, PMI supports malaria elimination activities, procurement of antimalarial commodities based on identified gaps, surveillance for antimalarial drug resistance, and insecticide resistance and vector monitoring activities. The PMI VectorLink Project will be providing entomological surveillance and monitoring to help inform vector control program decisions.
