View the latest updates from the World Mosquito Program in Rio de Janeiro.

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

The World Mosquito Program has been active in Brazil since 2012, when it was called Eliminate Dengue: Brazil Challenge. Between August 2015 and January 2016, the project released Wolbachia Aedes aegypti in two areas: Tubiacanga, on Governador Island in the city of Rio de Janeiro, and Jurujuba, a neighborhood of Niterói. These pilot projects have been monitored since early 2016 and have proven to be successful in establishing the Wolbachia mosquito population.
