dengue Cases in 2025: A Snapshot

As of April 5, 2025, Indonesia’s Ministry of Health (Kemenkes) has reported 36,855 cases of dengue fever. This translates to an Incidence Rate (IR) of 13.01 per 100,000 people. Tragically,173 deaths have been attributed to the disease,resulting in a Case Fatality Rate (CFR) of 0.47%. The spread of dengue spans across 445 districts and cities within 34 provinces, with fatalities reported in 94 regencies and cities across 24 provinces.

Comparative Analysis: 2024 vs. 2025

In 2024, Indonesia faced a more severe dengue outbreak, with 257,271 cases reported, yielding an Incidence Rate (IR) of 91.93 per 100,000 residents. The death toll reached 1,461, resulting in a Case Fatality Rate (CFR) of 0.57%.The disease was present in 488 regencies and cities across 37 provinces, with deaths occurring in 283 districts and cities within 32 provinces.

While the number of cases and deaths are lower in 2025 compared to 2024, vigilance remains crucial. The extensive geographical distribution of dengue underscores its status as a persistent national health challenge.

Positive Trends: Improved Clinical Handling and Public Awareness

Aji Muhawarman, Head of the Dialogue and Services Bureau at the Ministry of Health, noted a positive trend. The decline in the Case fatality rate (CFR) from 0.57 to 0.47 suggests potential improvements in clinical management and increased public awareness.

Geographic Hotspots and Post-Lebaran Vigilance

Despite the overall decrease in cases,health officials are urging increased vigilance,particularly in provinces with the highest dengue burden: West Java,Central Java,East Java,Bali,and Lampung. The anticipated surge in urbanization following the Lebaran homecoming celebrations could exacerbate the spread of the disease.

Innovative Solutions: The Wolbachia Mosquito Project

Indonesia is exploring innovative solutions to combat dengue fever, including the Wolbachia technology.This involves introducing mosquitoes infected with Wolbachia bacteria, which can inhibit the dengue virus’s ability to replicate within the mosquito. This groundbreaking initiative is currently undergoing a pilot project in five cities: West Jakarta (DKI Jakarta), Bandung (West Java), Semarang (Central Java), Bontang (East Kalimantan), and kupang (NTT). The project aims to assess the effectiveness of Wolbachia in reducing dengue transmission.

The pilot project is expected to continue until mid-2025,after which the results will be evaluated to determine the feasibility of wider implementation.

Mosquito Technology Innovation Aedes Egypt Being TOLBACHIA is now in Indonesia has been implemented in 5 cities as a pilot project implementation.

Early Results of the Wolbachia Pilot project

Preliminary results from the pilot project, released in 2024, indicate promising outcomes. The Wolbachia population has successfully reached 60% or more in the intervention areas, suggesting a significant impact on the mosquito population’s ability to transmit dengue.
