Commentary: The real achievement behind 10 years of Project Wolbachia in Singapore’s dengue fight

TRUST AS THE FOUNDATION OF PUBLIC HEALTH INNOVATION

No public health intervention succeeds without public trust. Mosquitoes are generally seen as nuisances, so how could the public trust that releasing even more mosquitoes made sense?

Field trials in residential neighbourhoods were needed to move beyond controlled experimental settings, to understand how the bred insects interacted with the environment and wild mosquitoes. 

Engagement had to be treated not as a one-off exercise, but as an ongoing process. It involved not just explaining the safety and purpose of the releases to residents and community groups but also taking in their feedback to understand the ground situation and improve communication materials.

Residents needed reassurance that Wolbachia releases consisted of male mosquitoes that do not bite, and that they can continue with their usual mosquito control measures. It was also important to convey that residents maintain vigilance in preventing mosquito breeding. Success depended not just on the technology, but on sustained community participation.
