Review of Dengue Prevention Strategies to Ameliorate Dengue Infection Rate Given Heightened Numbers in 2024
- The Ministry highlighted that dengue cases in 2024 have already exceeded the total for 2023, driven by high Aedes mosquito populations, low population immunity to all four dengue serotypes, and warm, humid weather that accelerates mosquito breeding and virus multiplication.
- The National Environment Agency (NEA) has intensified efforts, including collaborating with Town Councils for inspections and flushing of drains, launching the National Dengue Prevention Campaign earlier than usual, and using volunteers and digital platforms to raise public awareness.
- These collective measures have shown positive results, with a 20.8% drop in dengue cases and a 16% reduction in clusters in the second quarter of 2024 compared to the first quarter.
- Project Wolbachia, which uses mosquito releases to suppress the Aedes aegypti population, has achieved 80-90% reductions in study sites and is being expanded to cover 480,000 households, though further studies are needed to improve cost-effectiveness before wider deployment.
- The Ministry emphasized that while initiatives like Project Wolbachia are promising, sustained community action—such as removing stagnant water and taking personal precautions—remains essential to curb dengue transmission.
