Dengue Cases in Batam More Contained by Mid-2026

Dengue Haemorrhagic Fever (DBD) cases in Batam City are showing a more contained trend in 2026. As of 21 June 2026, the Batam City Health Office (Dinkes) recorded 205 cases with no reported fatalities. This achievement marks a positive development compared to previous years. In 2024, DBD caused 14 deaths in Batam, while in 2025 there were three fatalities from the disease. Head of the Batam City Health Office, dr Didi Kusmarjadi, stated that the decline in DBD cases this year indicates that control efforts by the government and the community are beginning to yield results. “Alhamdulillah, up to the middle of this year there have been no reports of deaths from DBD. However, the public must not be complacent because the potential for transmission still exists. Prevention must continue consistently,” he said on Monday (22/6). According to Health Office data, the number of DBD cases in 2026 is far lower than in previous years. In 2025, 809 cases were recorded, in 2024 there were 871 cases, and in 2022 the figure reached 902 cases. The decline is also reflected in the Incident Rate (IR). This year, Batam’s DBD IR stands at 15.28 per 100,000 population, down from 60.28 per 100,000 in 2025 and 68.21 per 100,000 in 2024. In terms of distribution, the Sei Langkai Community Health Centre recorded the highest number of cases with 44, followed by Batu Aji with 27 cases and Tanjung Uncang with 20 cases. The productive age group above 15 years still dominates DBD cases in Batam. Of the total 205 cases, 122 were male and 83 were female. He explained that the decline in cases is inseparable from strengthened surveillance, epidemiological investigations, the mosquito nest eradication movement (PSN), and community involvement in maintaining environmental cleanliness. According to him, prevention measures at the household level are the main key to suppressing the spread of DBD. The public is urged to routinely practise the 3M Plus approach: draining water containers, tightly sealing water storage, and reusing or recycling used items that could become mosquito breeding sites. He stressed that fogging is not the primary solution for eradicating DBD. Fogging only kills adult mosquitoes, while larvae can continue to develop if breeding sites are not cleaned. Therefore, the most effective effort is to break the mosquito life cycle by eliminating breeding places. The Batam Health Office continues to monitor the development of cases through all community health centres and hospitals.
