Dengue Fever Trends Declining in West Jakarta
The West Jakarta Health Office (Sudinkes) has recorded a decline in Dengue Fever (DBD) cases within the region over the past three months. Data from the office shows that 335 cases were recorded in April 2026, 197 cases in May 2026, and only one case reported as of 4 June 2026.
“The trend over the last three months has indeed shown a decrease. However, this decline should not lead to complacency, as climate predictions from BMKG indicate that our environmental conditions remain optimum for the life cycle of the dengue-transmitting mosquito,” said the Head of the West Jakarta Health Office, Sahrun_una, when contacted in Jakarta on Friday.
Despite the drop, the public is urged to remain vigilant as current weather conditions continue to support the breeding of the Aedes Aegypti mosquito. According to predictions from the Meteorology, Climatology, and Geophysics Agency (BMKG), the climate suitability for Dengue Fever in June 2026 shows an average relative humidity (RH) reaching 80 per cent. This figure falls within the optimum humidity range for mosquito growth, which is between 71 and 83 per cent.
Furthermore, air temperatures in West Jakarta are predicted to range between 24 and 31 degrees Celsius, approaching the optimum average temperature for mosquito development of 25 to 27 degrees Celsius. BMKG also predicts that the monthly Dengue Fever Incident Rate (IR) could potentially reach 7.6 cases per 100,000 residents.
Addressing these climatic challenges, Sahruna stated that all community health centres (Puskesmas) in West Jakarta are continuously tightening periodic monitoring of incident rates and the speed of dengue transmission in the field. Rapid intervention measures are being implemented through Epidemiological Investigations (PE) and the strengthening of the Mosquito Nest Eradication Movement (PSN) using the 3M Plus method (Draining, Covering, and Recycling).
He emphasised that the key to successful disease control lies in the early detection of mosquito larvae, which relies on community awareness. “Community health centres are actively monitoring vectors or dengue larvae in residential areas. We prioritise the active participation of the community as independent mosquito larvae monitors (Jumantik) in their own homes, accompanied by increased health promotion regarding the dangers of Dengue Fever,” said Sahruna.
