With Singapore entering its peak dengue season, families are urged to stay informed and proactive. Despite a significant drop in cases this year, the threat remains, especially with the potential resurgence of the Zika virus. Understanding the current situation and adopting preventive measures is crucial to safeguarding your loved ones.
Dengue Update: A Promising Decline but Continued Vigilance Needed
As of May 2025, Singapore has reported approximately 2,000 dengue cases, marking a 74% decrease compared to the same period in 2024. This decline is attributed to enhanced community efforts, including the expansion of Project Wolbachia, which involves releasing male mosquitoes infected with the Wolbachia bacteria to curb the Aedes mosquito population.
However, experts caution against complacency. The low population immunity and the presence of multiple dengue virus serotypes mean that the risk of outbreaks persists. Continued vigilance and adherence to preventive measures are essential to maintain this downward trend, especially when you’re a pregnant woman. A dengue fever in a pregnant woman can transmit the virus to her unborn child, which can raise problems of low birth weight, premature birth, or even fetal death.
Zika Concerns: Staying Alert Amidst Low Case Numbers
While no new Zika cases have been reported in Singapore since March 2025, the potential for resurgence remains. The Aedes mosquito, responsible for transmitting both dengue and Zika viruses, continues to thrive in urban environments. Given the serious health implications of Zika, particularly for pregnant women, maintaining preventive practices is crucial.
Understanding the Peak Season: When Are Families Most at Risk?
Singapore’s dengue cases typically rise during the warmer months, with peaks observed from May to October. Factors such as increased rainfall and higher temperatures during this period create ideal breeding conditions for mosquitoes. Families should be especially cautious during these months and implement preventive measures diligently.
Follow the B.L.O.C.K Steps: Eliminating Mosquito Breeding Grounds
The National Environment Agency (NEA) recommends the B.L.O.C.K steps to prevent mosquito breeding:
-
B: Break up hardened soil in potted plants.
-
L: Lift and empty flowerpot plates.
-
O: Overturn pails and wipe their rims.
-
C: Change water in vases regularly.
-
K: Keep roof gutters clear and place BTI insecticide inside. CNA+1HealthXchange+1
Implementing these steps weekly can significantly reduce mosquito breeding sites around your home.
S.A.W. Actions to Prevent Bites: Personal Protection Measures
In addition to eliminating breeding sites, personal protection is vital. The NEA advises the following S.A.W. actions:
-
S: Spray insecticide in dark corners around the house.
-
A: Apply mosquito repellent regularly.
-
W: Wear long-sleeved tops and long pants.
These measures are especially important during peak mosquito activity times, such as early morning and evening.
The significant reduction in dengue cases in 2025 is encouraging, but the battle against mosquito-borne diseases is ongoing. Families must remain vigilant, especially during the peak season, by implementing the B.L.O.C.K and S.A.W. strategies. Through collective effort and consistent preventive measures, we can protect our loved ones and communities from the threats of dengue and Zika viruses.
Frequently Asked Questions (FAQs)
What is Project Wolbachia?
A: Project Wolbachia involves releasing male mosquitoes infected with the Wolbachia bacteria, which prevents them from producing offspring, thereby reducing the mosquito population.
Are there any recent Zika cases in Singapore?
A: No new Zika cases have been reported since March 2025, but continued vigilance is necessary to prevent potential outbreaks.
When is the dengue peak season in Singapore?
A: Dengue cases typically peak from May to October, coinciding with warmer temperatures and increased rainfall.
How can I protect my family from mosquito bites?
A: Implement the B.L.O.C.K steps to eliminate breeding sites and follow the S.A.W. actions for personal protection
