Bali dengue cases fall 82.6% in first seven months of 2026

Denpasar — — Bali recorded 1,588 dengue fever cases between January and July 2026, according to data from the provincial Health Office cited by local media. The figure is sharply lower than the 9,116 cases reported over the same period in 2025, a decline of about 82.6 percent.

Local outlet Bali.live reported the drop on 7 September 2026, summarising figures from the Bali Provincial Health Office and local newspapers. NusaBali.com separately reported that, based on Health Office data up to 31 July 2026, Bali recorded 1,588 dengue cases and two deaths, compared with 9,116 cases in the same period of 2025. These reports indicate that the comparison covers province-wide, reported dengue cases under consistent surveillance by the health authorities.

Deaths linked to dengue have also fallen. Bali.live reported 13 dengue-related deaths in all of 2025 and two deaths by mid‑2026. NusaBali.com, citing provincial Health Office data, likewise reported two dengue fatalities between January and July 2026, one in Buleleng and one in Denpasar. Other media reports using Health Office data put total dengue deaths in 2025 at 13 or 14, depending on the period covered, but agree that fatalities in 2026 remain far lower.

Denpasar and Badung show declining trends

Denpasar has seen a marked decline in reported dengue cases in 2026. Bali.live reported that the city recorded 162 cases between January and July 2026, compared with 1,197 cases in the same period of 2025. Earlier in the year, Tribun Bali reported that Denpasar logged 96 dengue cases from January to 23 April 2026, down from 928 cases in the same period of 2025, based on Denpasar Health Office data.

In Badung, NusaBali.com reported that the regency recorded 340 dengue cases between January and August 2026. Monthly figures showed 63 cases in January, falling to 28 cases in August, with intermediate fluctuations. Local health officials in Badung described the 2026 numbers as far more controlled than in 2025, when monthly cases had reached 377 in February and 88 in August.

Province‑wide, detailed monthly data published by NusaBali.com show 281 dengue cases in January 2026, 277 in February, 246 in March, 264 in April, 195 in May, 189 in June and 136 in July. An earlier report from Bali Post gave similar cumulative figures up to mid‑May 2026, with 1,167 cases and two deaths, and highlighted Gianyar and Badung as the regencies with the most cases at that point.

Health authorities maintain mosquito‑control efforts

Despite the sharp decline, health authorities are continuing prevention and control measures. Bali.live reported that the Denpasar Health Department plans to carry out ULV fogging in September 2026 in streets, parks, sports grounds and other public areas, targeting adult mosquitoes. Tribun Bali likewise reported continuing fogging operations in Denpasar as cases declined, citing city Health Office officials.

Health officials have repeatedly emphasised that fogging alone is not sufficient to control dengue. According to Bali.live, residents are being urged to eliminate standing water, cover water containers and remove items that can become breeding sites after rain, with recommended household inspections at least once a week. Other local reports from the provincial and district health offices echo calls for community participation in draining, covering and disposing of potential mosquito breeding sites.

Implications for travellers and residents

The decline in reported dengue cases reduces overall risk but does not remove it. The Bali Provincial Health Office and local media continue to warn of potential case increases during the rainy season and urge vigilance. Available reports do not provide a current, formal travel‑health alert or detailed risk comparisons among Bali’s districts, but they support maintaining standard mosquito precautions for both residents and visitors, including using repellents, wearing long sleeves and avoiding standing water.

Bali’s climate typically features a wetter period roughly from late year into the first months of the following year, when warm, humid conditions can favour mosquito proliferation. Health officials say prevention campaigns and monitoring will continue through the end of 2026 in anticipation of possible case rises when rains return.
