The dengue fever outbreak, which traditionally appears on the island during the rainy season, is gradually declining. Of course, not all cases are officially recorded—if symptoms are relatively mild, people often don’t seek medical attention. However, the trend is still clear.
In March 2025, the number of reported dengue cases dropped to 861, with one registered death. In January, there were 1,542 cases with two fatalities. February saw the highest number of cases—1,843—with four deaths.
The decline in dengue cases is attributed to both weather conditions and government measures. Bali authorities have strengthened mosquito control, especially in areas with the highest number of cases, such as Denpasar city and the Badung and Gianyar regencies.
“If we look at previous years, these three regions have always topped the list for dengue fever cases. We’ve already launched a dedicated program: inspectors in these regions go door to door, check for mosquito presence, and educate the public at the same time,” said Dr. I Gusti Ayu Raka Susanti, head of the Bali Provincial Health Department.
Dr. Raka noted that dengue cases can occur year-round, so it’s important to continuously remind the public about eliminating mosquito breeding grounds. Residents can also get vaccinated to prevent the disease. The dengue vaccine is available for children aged 6 and adults up to 45 years old.
“At the moment, the dengue vaccine is not part of the national immunization program. It can only be obtained on a voluntary basis,” she explained.
