You’re planning your dream trip to Bali—admiring the beauty of Jatiluwih rice terraces, diving in crystal-clear waters, and enjoying beachside sunsets. But then, someone mentions malaria risk in Bali. Do you need malaria pills for Bali in 2025? Or is this just unnecessary worry?
The truth is, malaria is not a risk in Bali’s main tourist areas, but it is present in other parts of Indonesia. If you’re venturing beyond Bali—to see Komodo dragons in Komodo National Park, waterfalls in Sumba or rural areas—you may need protection. Let’s break down exactly where malaria is a concern and how to stay safe.
What is Malaria?
Malaria is a life-threatening disease caused by parasites, Plasmodium, transmitted primarily through the bites of infected Anopheles mosquitoes(1). Anopheles mosquitoes usually bite between dusk and dawn(1). While less common, malaria can also be spread through blood transfusions, needle sharing, organ transplantation, and from mother to child during pregnancy(1).
Where in Indonesia is Malaria a Risk?
Malaria is common in tropical and subtropical areas worldwide, including Africa, Latin America, the Caribbean, Asia, and the South Pacific.(1).
