ndonesia recorded its highest number of malaria cases in 2025 mainly driven by population mobility and climate change that hamper elimination efforts to reduce patients, especially in high-burden regions such as Papua.
Last year, the Health Ministry recorded 706,000 malaria cases across the archipelago, an increase from 543,000 in 2024 and 418,000 in 2023.
“In 2025, we recorded the highest number of cases, with fluctuations largely driven by population mobility and weather conditions that contributed to rising cases across regions,” Health Ministry communicable diseases director Prima Yosephine said in a press briefing on April 30.
Despite 412 of 514 regencies across the country having declared malaria-free, the disease remains rampant in the country’s easternmost regions, with more than 95 percent of all reported cases found in six provinces across Papua. The highest concentration of cases were detected in Papua province.
Elimination efforts in Papua continue to face challenges due to the region’s vast forested area, Prima said, where many local communities live and work, Prima said. The topography made it difficult for health authorities to reach them as well as distribute healthcare services and infrastructure.
Malaria is an infectious disease caused by the Plasmodium parasite spread through the bites of a female Anopheles mosquito infected by the pathogen. The mosquito requires small and seasonal bodies of water for their larvae and pupae to grow, making swamps tropical and rainforests in Papua suitable habitats for the Anopheles.
