Singapore deploys Mosquitoes to Combat Dengue in Innovative Strategy

singapore is taking a counter-intuitive approach to fighting dengue fever. The National Environment Agency (NEA) is breeding and releasing millions of mosquitoes, but with a twist: these mosquitoes are infected with Wolbachia, a bacterium that blocks the transmission of the dengue virus.

The Wolbachia Breakthrough

the Aedes aegypti mosquito is a primary vector for the dengue virus,which threatens billions globally. The World Health Organization (WHO) estimates that up to 100 million people are infected annually, with thousands of deaths, underscoring the urgent need for effective control measures. Singapore’s strategy hinges on Wolbachia, a naturally occurring bacterium.

Wolbachia modifies the mosquito’s physiology preventing it from transmitting dengue. Moreover, when male mosquitoes carrying Wolbachia mate with uninfected females, their eggs frequently enough fail to hatch, thus reducing the mosquito population over time. this method, initially developed by the World Mosquito Program, has been in practice for a decade, with trials in Australia, New Caledonia, and now, a elegant implementation in Singapore.

Automated Sorting for Optimal Results

A challenge arises when both male and female mosquitoes are infected with Wolbachia,potentially negating the virus-blocking effect. To address this, NEA employs an innovative automated sorting system using machine learning and computer vision.

The system scans mosquito pupae to identify and separate females. only female mosquitoes infected with Wolbachia are released, maximizing the effectiveness of the program. Singapore aims to considerably reduce dengue transmission through this precise method.

Researchers hope that this approach will further increase the effectiveness of this method, and this is good news for the citizens of singapore, where dengue continues to be a considerable public health problem.

Did You Know?
The World Health Organization estimates that dengue fever infects 50 to 100 million people each year, leading to notable public health challenges globally.

Ecological Considerations

While controlling mosquito populations is crucial,complete eradication poses ecological risks. Mosquitoes serve as a food source for various species. The World Mosquito Program is exploring alternative methods to prevent virus circulation without decimating mosquito populations.

Princeton University teams, for example, are working on approaches that target the virus itself, minimizing the impact on the mosquito population.
