Is dengue fever a risk in Bali?
Checked October 2026 · 3 sources
Yes. Dengue is spread by mosquitoes in Bali all year, and cases usually rise in the wet season, roughly November to April. Local reports counted 10,391 cases in 2025. Cases fell about 83% in January to July 2026 compared with the same months of 2025. Avoiding mosquito bites is the main protection.
In detail
Local media, citing Bali Post and Bali Tribune, reported 1,588 cases from January to July 2026, compared with 9,116 in the same period of 2025. Australian authorities have reported dengue in travellers returning from Bali. Zika and chikungunya, which are spread by the same mosquitoes, have also been reported in visitors.
The mosquitoes that carry dengue mostly bite during the day, including in towns and resorts. Use a repellent containing DEET, picaridin or similar, wear light clothing that covers your arms and legs, and choose rooms with screens or air conditioning.
Symptoms include high fever, severe headache, pain behind the eyes, and joint or muscle pain. See a doctor quickly if you get a fever in Bali or after you return. Do not take ibuprofen or aspirin unless a doctor says so.
A dengue vaccine exists, but it is only advised for certain people, such as those who have had dengue before. Ask a travel-health professional whether it suits you.
Good to know
- Put on repellent in the morning and late afternoon.
- Choose accommodation with air conditioning or window screens.
