View the latest updates from the World Mosquito Program in Colombo.

The World Mosquito Program is working in Colombo to protect communities from mosquito-borne diseases like dengue, Zika, chikungunya and yellow fever.

In 2021, we completed the release of Wolbachia mosquitoes in Colombo Municipal Council-District 1 and Nugegoda, covering 20km2 and 240,000 residents. 

We are currently monitoring the Wolbachia mosquito population and dengue cases, and are encouraged by the preliminary results of Wolbachia establishing in the release areas.
