Home to 98 million people, Vietnam records around 110,000 dengue cases annually. At least 70% of all cases and 80% of dengue related deaths in the country are recorded in the Southern Vietnam region. But hundreds of thousands more cases will go undetected. For some, the symptoms can be severe and dengue does not discriminate between rich or poor, young or old. In March 2022, we started our first Wolbachia mosquito releases in two high-risk areas in the region – My Tho City, Tien Giang Province and Thu Dau Mot City, Binh Duong Province.
