Overview of the Dengue Fever Increase
Pasuruan City is experiencing a meaningful increase in dengue hemorrhagic fever (DHF) cases in 2025, with a 100% rise compared to the previous year. Health officials attribute this surge primarily to the effects of climate change, creating ideal breeding conditions for dengue mosquitoes.
Case Numbers and Public Health Response
According to the Pasuruan City Health Office,492 cases of dengue fever were recorded throughout 2025. This contrasts sharply with the 210 cases reported in 2024. Shierly marlena, Head of the Pasuruan City Health Office, confirmed that despite the increase, there have been no fatalities, and all patients have received appropriate medical care. She made this statement on Tuesday, December 30, 2025.
“our findings this year are higher than last year. No one died and everyone received good treatment,” stated Shierly Marlena.

The Role of Climate Change
Health officials emphasize that climate change is a major contributing factor to the rise in dengue cases. Increased rainfall and warmer temperatures create more standing water, providing breeding grounds for Aedes Aegypti mosquitoes. The warmer weather also accelerates the mosquito life cycle and extends the period when the virus can be transmitted.
Shierly Marlena explained, “Global climate change which accelerates the life cycle of mosquitoes plus human mobility spreads the virus.”
Contributing Factors beyond Climate
While climate change is a primary driver, other factors exacerbate the problem. These include poor sanitation practices, a high population density, and inadequate community behavior regarding mosquito control. Specifically, failing to drain water reservoirs, close water storage containers, and properly dispose of used items that can collect water contribute to mosquito breeding.
Preventative Measures and Public Advice
Given the ongoing rainy season and potential for flooding in Pasuruan City, health officials are urging residents to take proactive steps to prevent mosquito bites and eliminate breeding sites. These recommendations include:
- Implementing the “3 M” strategy: Menutup (closing), Menguras (emptying), and Mengubur (burying) potential mosquito breeding sites.
- Sprinkling larvicide in water reservoirs that are difficult to cover.
- Using mosquito repellent lotions.
- Wearing long-sleeved shirts and trousers.
- Pruning plants that can hold water.
