Buleleng: Gerokgak Records Highest Dengue Fever Cases in Early 2026

Cases of Dengue Fever (DBD) are currently elevated in the Buleleng Regency, Indonesia, with a notable concentration in the Gerokgak sub-district. Through the end of February 2026, a total of 72 cases had been recorded, with the majority originating in Gerokgak, the westernmost and largest sub-district in the region.

Rising Cases and Climatic Factors

According to Dr. Sucipto, Head of the Buleleng Health Department, 48 cases were reported in January and 24 in February, bringing the total to 72. Dr. Sucipto attributed the relatively high number of cases to unpredictable weather patterns. “This season has unpredictable weather, causing an increase in DHF cases,” he stated on February 20, 2026.

Gerokgak: A Focus Area

Gerokgak is under particular scrutiny due to both the highest number of cases and its unique characteristics. It’s the second-most populous sub-district in Buleleng, after Buleleng itself, and features diverse topography – ranging from coastal areas to hills – with widely dispersed settlements. These factors could complicate consistent control efforts without strong community participation.

Did You Know? Gerokgak is the largest sub-district in Buleleng Regency.

Elevated case numbers were also reported in the Tejakula and Kubutambahan sub-districts. Within Gerokgak, Pejarakan village recorded the highest number of cases at 10, followed by Sembiran with 7, and Pemuteran and Pakisan each with 5.

Demographic Impact and Response

The data indicates that the 14–44 year-old age group, considered the most productive segment of the population, accounts for the largest proportion of cases, representing 47.2 percent of those affected. The 5–14 year-old age group represents 30.6 percent of cases.

Dr. Sucipto indicated that fogging has been implemented in areas with high case numbers, and mosquito nest eradication (PSN) efforts are being intensified through local health centres. However, he emphasized that the size of Gerokgak necessitates active involvement from communities at the village and hamlet levels.

Expert Insight: The emphasis on community involvement highlights the critical role of localized, sustained efforts in controlling mosquito populations and preventing further spread of Dengue Fever, particularly in areas with challenging geographical features and dispersed populations.

The Buleleng Health Department has confirmed that all healthcare facilities are prepared to treat DBD patients. Prevention remains a priority to avoid further increases in cases and potential fatalities amidst fluctuating weather conditions.
