Tourists traveling to Bali are being urged to take the risk of Dengue Fever seriously, even during the dry season.

Typically, the worst time of year for dengue fever in Bali is during the monsoon season; however, medical professionals are noting that as rates drop seasonally, the risks remain present. 

The Wangaya Regional General Hospital in Denpasar has recorded 636 cases of Dengue Fever in the year so far.

The updated figures have been shared by the Head of Public Relations for Wangaya Hospital, Anak Agung Ayu Dewi Purnami. He confirmed that there has been one recorded death due to Dengue Fever in a patient who was admitted to the hospital in April 2025.

Sharing statistics for all of Denpasar, the Head of the Denpasar City Health Office, AA Ayu Agung Candrawati, noted that the spike in Dengue Fever cases in 2025 corresponded with the monsoon season from early January to the end of March and the beginning of April.

Of the hundreds of cases recorded by the Denpasar City Health Office, many more would have gone unreported and undetected. In the city, a total of five Dengue Fever deaths were recorded between January and May 2025. 

Candrawati told reporters, “The rainy season that started earlier, since October 2024, made the spread of Aedes Aegypti mosquitoes faster, so that dengue cases began to increase since January 2025.”

Candrawati told reporters that one of the main obstacles faced by the Denpasar City Health Office in preventing Dengue Fever in the province is the lack of public awareness about the risks and prevention techniques, as well as little awareness about symptoms and treatment protocols.

He told reporters that as a prevention effort, the Health Office continues to carry out strategic programming and campaigning, including education, epidemiological investigation, as well as mass fogging on city streets, which commenced at the beginning of April 2025.

He added, “We invite the public to maintain a clean environment, recognize the symptoms of dengue fever, implement clean and healthy living behaviors, and increase the role of Jumantik Mandiri in every household so that dengue cases can be suppressed and the death rate can be minimized.”

As part of community based programs that help mitigate the spread of Dengue Fever a Jumantik Mandiri is an Independent Larvae Monitoring Officer or dedicated member of each household who takes on the responsibility of checking all areas in the home and property where mosquito larvae could breed. 

As described by the World Health Organisation, “Dengue (break-bone fever) is a viral infection that spreads from mosquitoes to people. It is more common in tropical and subtropical climates. 

“Most people who get dengue will not have symptoms. But for those who do, the most common symptoms are high fever, headache, body aches, nausea, and rash. Most people will recover in 1–2 weeks. Some people develop severe dengue and require hospital care. In severe cases, dengue can be fatal.” 

Tourists traveling to Bali or anywhere in Indonesia should be aware of the risks of Dengue Fever, take adequate precautions, and be vigilant for the onset of symptoms.

It is also vitally important that all tourists traveling to Bali and Indonesia have fully comprehensive medical insurance that covers tropical diseases such as Dengue Fever.

Tourists should read their policy documents in full and be clear about what is and is not covered by the policy, should they need to make a claim.

Many hospitals and clinics in Bali refuse to treat a patient until health insurance providers have approved and confirmed that they will pay out, or if the patient or their next of kin have confirmed that they can pay for treatment privately. 

The Australian travel advice bureau, Smartraveler, advises tourists to “Take care to avoid mosquito bites at all times. Be extra cautious during early mornings and late afternoons. This is when mosquitoes are most active.”

“Avoid areas with a lot of mosquitos. For example, near stagnant water. Wear long, loose, light-colored clothing and closed shoes. Use insect repellent. If you use both sunscreen and repellent, apply the sunscreen first.”
