JAKARTA - Deputy Governor of DKI Jakarta Rano Karno reminded the public to be aware of the potential increase in dengue fever cases (DBD) as an impact of the El Nino phenomenon which is expected to occur in the second semester of 2026.
According to Rano, the predicted longer transition phase of the haze is accompanied by increasingly hot air temperatures that have the potential to trigger the development of Aedes aegypti mosquitoes, the cause of DBD.
"The first disease that we will face, if El Nino occurs, is DBD. We will deal with the transition period of the eclipse, which is expected to be much longer and Jakarta or Indonesia much hotter," said Rano in Jakarta, Sunday, April 12.
As a precautionary measure, the DKI Jakarta Provincial Government held simultaneous volunteer work in eight sub-districts in West Jakarta, namely Kebon Jeruk, Cengkareng, Kalideres, Grogol Petamburan, Kembangan, Palmerah, Tambora, and Taman Sari.
The activities are focused on handling environmental issues, ranging from the transportation of selective waste, mud, channel normalization, cleaning of rivers and bodies of water, to the demolition of buildings that cover water channels.
Rano emphasized that a dirty and many puddles environment has the potential to become a mosquito nest that causes DBD, so it must be cleaned immediately.
"This means that if we don't clean up piles like this, it will become a mosquito nest that causes DBD and is very dangerous for children," he said.
In addition, volunteer work also includes tree felling, pedestrian path repair, and arranging electrical cables to create a safer and healthier environment.
He hopes that this activity will not stop as a temporary agenda, but will develop into a routine and sustainable movement throughout the Jakarta region, including the Thousand Islands.
"Hopefully this movement will be followed by all regions in Jakarta, including the Thousand Islands," he said.
Meanwhile, based on data from the DKI Jakarta Health Office, there are 10 sub-districts with the highest number of DBD cases throughout 2022 to 2025, including Cempaka Putih, Pasar Rebo, Mampang Prapatan, Kelapa Gading, and Kembangan.
In the last decade, the peak of DBD cases in Jakarta generally occurs in April, coinciding with the transition period of the season which is marked by an increase in air temperature and rainfall.
