As the world becomes increasingly connected, a health threat anywhere is a threat everywhere and to everyone. More than one million cases of mosquito-borne diseases have been reported in Colombia. Mosquito-borne diseases like dengue negatively impact the livelihood of many families. Since 2019, we have been working to significantly reduce these numbers in Cali, Colombia through our Wolbachia method. Our partners Universidad de Antioquia, Bill & Melinda Gates Foundation, Wellcome and USAID have been key supporters of this work.
