First trial begins in Vietnam

On 3rd April the Eliminate Dengue project in Vietnam began the first trial of the Wolbachia dengue control method in that country. The trial is taking place on Tri Nguyen Island, Khanh Hoa province on the south central coast of Vietnam and involves weekly releases of Aedes aegypti mosquitoes (pupae) that contain the strongest dengue blocking Wolbachia strain wMelPop.

We will monitor mosquitoes on the Island and determine whether the wMelPop strain establishes in the wild mosquito population. The results of the trial will be reported back to island residents and project collaborators.
