Background: This report is based on the 2021 annual meeting of the Asia-Pacific Malaria Elimination Network Surveillance and Response Working Group held online on November 1-3, 2021. In light of the 2030 regional malaria elimination goal, there is an urgency for Asia-Pacific countries to accelerate progress towards national elimination and prevent re-establishment. The Asia Pacific Malaria Elimination Network (APMEN) Surveillance Response Working Group (SRWG) supports elimination goals of national malaria control programmes (NMCPs) by expanding the knowledge base, guiding the region-specific operational research agenda and addressing evidence gaps to improve surveillance and response activities.

Article Synopsis
  • Cambodia is working towards eliminating malaria by 2025 but faces challenges with Plasmodium vivax (P.v) due to the high prevalence of G6PD deficiency, which complicates treatment options.
  • The study conducted in Pursat province involved creating and evaluating a new care pathway for treating P.v infections while considering G6PD status, using a collaborative approach with local stakeholders.
  • The new care pathway included point-of-care G6PD testing, referral systems, and community follow-up by Village Malaria Workers to enhance treatment adherence and improve health outcomes for patients.

Article Synopsis
  • Malaria cases in Cambodia dropped significantly (90.8%) from 2010 to 2020, but a surge occurred in 2018, prompting the National Center for Parasitology, Entomology and Malaria (CNM) to launch the "Intensification Plan" (IP).
  • The IP involved strategic site selection, intervention tactics in health facility catchment areas, and thorough monitoring of malaria data from 2018-2020.
  • Implementing the IP led to a remarkable 96.2% reduction in Plasmodium falciparum/mixed cases in targeted areas, contributing to an overall decline in malaria cases across Cambodia.

Village Malaria Workers (VMWs) are lay people trained to provide a valuable role in frontline testing and treatment of malaria in rural villages in Cambodia. Emergence of artemisinin-resistant malaria highlights the essential role of such VMWs in surveillance and early treatment of malaria. Smartphone technology offers huge potential to support VMWs in isolated and resource-poor settings.

Mass-screen-and-treat and targeted mass-drug-administration strategies are being considered as a means to interrupt transmission of Plasmodium falciparum malaria. However, the effectiveness of such strategies will depend on the extent to which current and future diagnostics are able to detect those individuals who are infectious to mosquitoes. We estimate the relationship between parasite density and onward infectivity using sensitive quantitative parasite diagnostics and mosquito feeding assays from Burkina Faso.

Background: Artemisinin-resistant Plasmodium falciparum malaria has recently been identified on the Thailand-Cambodia border and more recently in parts of Thailand, Myanmar and Vietnam. There is concern that if this resistance were to spread, it would severely hamper malaria control and elimination efforts worldwide. Efforts are currently underway to intensify malaria control activities and ultimately eliminate malaria from Cambodia.

Background: Accurate malaria stratification is essential for effective targeting of interventions but represents a particular challenge in pre-elimination settings. In these settings transmission is typically sufficiently low and spatially heterogeneous to warrant a need for estimates of malaria risk at sub-district or village level but is also likely to be sufficiently high to render the type of decision support systems appropriate to the final stages of malaria elimination impractical. In such a scenario it is arguably more feasible to strengthen existing passive malaria surveillance systems so that routinely generated case data can provide an effective basis for stratifying malaria risk.
