The World Mosquito Program is working in the Nha Trang region, on Vietnam’s South Central Coast to help protect communities from mosquito-borne diseases like dengue, chikungunya and yellow fever.
After conducting laboratory studies to examine the impact of Wolbachia on dengue and chikungunya viruses in Vietnam, and engaging with the community to explain our Wolbachia method and gain their acceptance, we released Wolbachia mosquitoes on Tri Nguyen Island in 2013 and within the community of Vinh Luong in 2018.
We are now evaluating both the levels of Wolbachia in the mosquito population and the impact of Wolbachia on the transmission of dengue and other mosquito-borne diseases.
Our analysis of disease data from local health authorities indicates there is lower dengue incidence in the release area than in the nearby urban centre of Nha Trang since completion of releases, whereas prior to releases these areas were highly comparable in their dengue epidemic cycles.
We’ve been working with communities in Vietnam since 2006 to help prevent mosquito-borne diseases. Read our progress updates to see our latest news.
