Malaysia Sees Dramatic Drop in Dengue Cases & Deaths: A Promising Trend & innovative Solutions
December 18, 2025 – Malaysia is experiencing a significant and encouraging decline in dengue fever cases and related fatalities. New data reveals a 61.3% reduction in deaths, falling to 43 cases this year compared to 111 in the previous year. This positive trend extends to overall case numbers, with a 56.5% decrease reported nationwide as of December 6th - 51,046 cases versus 118,291 in all of 2024.
Health Minister Datuk seri Dr. Dzulkefly Ahmad expressed optimism that this downward trajectory will continue thru the end of December, potentially maintaining the current figure of 51,046 cases. He lauded the success of public health programs and the collaborative efforts of all involved parties in controlling the spread of this mosquito-borne illness.
The Role of Wolbachia Mosquitoes in Dengue Control
A key component of Malaysia’s success lies in its innovative use of Wolbachia mosquitoes. As 2019, the Health Ministry has been strategically releasing these mosquitoes, which carry a natural bacteria that inhibits the transmission of the dengue virus.
This biological control method isn’t a replacement for customary approaches, but rather a powerful complement. It works alongside established strategies like eliminating mosquito breeding grounds and targeted chemical control. This integrated approach aligns with recommendations from the World Health Organization (WHO) for sustainable vector control.
The recent opening of the Putrajaya Wolbachia Insectarium – the second such facility in the country – signifies a strengthened commitment to this program. This facility will bolster the nationwide Wolbachia Mosquito Operation, increasing the capacity for mosquito rearing and release.
A Whole-of-Nation Approach to Public Health
The success in curbing dengue fever isn’t solely attributable to scientific advancements.It’s a testament to a “whole-of-nation” approach, emphasizing collaboration across government agencies and local communities.
Datuk Seri Dr. Zaliha mustafa, Minister in the Prime Minister’s Department, highlighted the commitment of local authorities, noting the repurposing of a previously unused building into the new insectarium.This demonstrates a proactive effort to leverage existing resources for public benefit.
Here’s what you need to know about the current situation:
* Significant Decline: Both dengue deaths and overall cases have decreased substantially.
* Wolbachia Impact: The release of Wolbachia-infected mosquitoes is proving to be a valuable tool.
* Integrated Strategy: Combining biological control with traditional methods is key.
* Government Support: strong commitment from both the Health Ministry and local authorities.
