Is Malaria still exist in ASEAN countries?

By

Malaria in ASEAN Countries: Yes, malaria remains endemic in several ASEAN countries, though the prevalence has declined significantly in recent years due to control efforts.

  • Key Countries Affected:
  • Myanmar: Highest burden in the region, with an estimated 140,000 cases in 2022 (WHO).
  • Indonesia: ~200,000 cases annually, concentrated in Papua and West Papua provinces.
  • Cambodia, Laos, Vietnam, and Philippines: Lower transmission, but sporadic outbreaks persist.
  • Brunei, Malaysia, Singapore, Thailand: Near elimination; Thailand reported <10,000 cases in 2022.
  • Rationale: The WHO Southeast Asia Region (including ASEAN) accounted for ~3% of global malaria cases in 2022, with Plasmodium falciparum and P. vivax as dominant species. Control measures (e.g., insecticide-treated nets, artemisinin-based therapy) have reduced incidence, but challenges include drug resistance (e.g., artemisinin resistance in the Greater Mekong Subregion) and cross-border transmission.
