JAKARTA - As many as 60 percent of the population of local mosquitoes in the Srengseng area, Kembangan, West Jakarta, already contains Wolbachia.

The presentation was due to the nursery of 1,119 Wolbachia buckets in the area some time ago.

"About 60 percent of the population of mosquitoes in Srengseng already contains Wolbachia, so the risk of spreading the dengue virus is getting smaller," said Head of the Kembangan Health Center, dr. Rosvita Nur Aini was quoted by ANTARA, Thursday, October 16.

He explained that the withdrawal of Wolbachia seed buckets had also been carried out because the marriage process between the Wolbachia mosquito and the local mosquito had been completed.

Nevertheless, said Rosvita, in order for the success of this program to have a more significant impact, people still need to eradicate mosquito nests (PSN).

"Residents still need to be vigilant and understand the dangers of dengue disease by continuing to maintain environmental cleanliness, as well as carrying out the PSN 3M Plus movement regularly, so that DHF prevention efforts continue to run effectively," he said.

Meanwhile, the Secretary of Srengseng Village, Rizki Dwipoetra, said that the implementation of this program is part of an effort to control Dengue Hemorrhagic Fever (DHF) through the Wolbachia program in his area.

"Alhamdulillah, the Wolbachia program has been completed and can run well. The DHF number in Srengseng has now dropped from first place to second place at the Kembangan sub-district level. Of course, this success has not escaped various existing elements and the Wolbachia program," he said.

In July 2025, Kembangan District became the second sub-district with the highest number of dengue cases in West Jakarta, with a scale of 12.4: 100,000 residents.

As for the West Jakarta area, the trend of dengue hemorrhagic fever (DHF) cases reported in the West Jakarta (Jakbar) area shows fluctuations have decreased from May to July 2025.

"The trend of dengue cases in the West Jakarta area in the last three months, May 355 cases, June 295 cases and July 282 cases. The data is up to July 31 at 14.00 WIB," said Head of the Disease Prevention and Control Section of the West Jakarta Health Sub-dept., Arum Ambarsari to ANTARA in Jakarta, Thursday (7/8).

The decline in cases occurred despite previous predictions that humidity and temperatures in July 2025 could potentially increase dengue cases.

"Based on the predictions of the Meteorology, Climatology and Geophysics Agency (BMKG), the climate suitability for DHF in July 2025 is 77 percent humidity, where the optimum humidity for mosquitoes is 71 - 83 percent, while the temperature ranges from 25 32 deg C, where the average temperature optimum for mosquito development is around 25 degC - 27 degC," said Arum.
