Baguio City in the Philippines is being evaluated as a pilot site for a new technology that uses naturally occurring Wolbachia bacteria to prevent mosquitoes from transmitting dengue fever.

The programme will cover over 800,000 households - half of Singapore's homes - by year-end, said the National Environment Agency.

Approximately 600,000 mosquitoes infected with Wolbachia bacteria are being released in Washington to prevent wild female mosquitoes from producing viable eggs, aiming to reduce mosquito populations without biting humans.

Dengue cases in Putrajaya, Malaysia, have fallen by 36.2 percent from January to April 2026, with the success attributed to the implementation of the Wolbachia method.

Singapore's Project Wolbachia celebrates a decade of achievements in combating dengue fever, showcasing how scientific breakthroughs can translate into effective public health realities through mosquito control.

A study has found that Singapore's expanded Project Wolbachia initiative successfully prevented almost 4,000 dengue cases in 2023, highlighting its effectiveness in combating the disease.
