As of May 25, 2025, Singapore has reported nearly 2,000 dengue cases this year, marking a remarkable 74% decrease compared to the same period last year, according to the National Environment Agency (NEA). This decline is attributed to heightened community vigilance and innovative initiatives like Project Wolbachia, which have played a crucial role in controlling the spread of the disease.
Community Vigilance and Prevention Efforts
The NEA has credited the reduction in dengue cases to strong community engagement in preventing mosquito breeding. The agency launched its National Dengue Prevention Campaign on the same day, coinciding with the onset of the traditional peak dengue season, which spans from May to October. Senior Minister of State for Sustainability and the Environment, Janil Puthucheary, emphasized the importance of public participation in eradicating potential mosquito breeding sites to minimize the risk of dengue and Zika virus transmission.
Despite the encouraging statistics, the NEA reported two dengue-related fatalities as of May 15, underscoring the ongoing threat posed by the disease. The warmer months typically see an uptick in dengue transmission due to the accelerated breeding of Aedes mosquitoes, which are responsible for spreading the virus.
Zika Virus Concerns
The NEA also highlighted that the same Aedes mosquitoes that transmit dengue can also carry the Zika virus. While Zika infections are generally mild for most individuals, they can have severe consequences for pregnant women, potentially leading to birth defects such as microcephaly. This risk further emphasizes the need for continued vigilance and preventive measures within the community.
Project Wolbachia’s Impact
The NEA’s Project Wolbachia has shown promising results, with studies indicating a 75% reduction in the risk of contracting dengue at release sites and a 45% reduction in surrounding areas. By the end of 2026, the initiative aims to benefit approximately 800,000 households, which represents about 50% of all households in Singapore.
In addition to ongoing community efforts, the NEA plans to trial the use of Wolbachia-infected Aedes mosquitoes in dengue clusters to enhance traditional control measures.
Conclusion
As Singapore enters its peak dengue season, the NEA’s proactive measures and community engagement are crucial in maintaining the downward trend in dengue cases. Residents are encouraged to practice preventive actions, such as the ‘B-L-O-C-K’ and ‘S-A-W’ methods, to protect themselves and their families from mosquito bites and reduce the risk of disease transmission.
