Eliminate Dengue Brazil is part of the World Mosquito Program, a global not-for-profit initiative that works to protect the global community from mosquito-borne diseases such as Zika, dengue and chikungunya.

After an absence of more than 20 years, dengue re-emerged in Brazil in 1981. Over the next 30 years 7 million cases were reported. Today, Brazil leads the world in the number of dengue cases with 3.2 million cases and 800 deaths reported from 2009-2014. Brazil has also been severely affected by outbreaks of Zika virus and chikungunya in the last few years.

Brazil’s first releases of Wolbachia mosquitoes began in September 2014 in Rio de Janeiro, after receiving government approval and support from the local community. Prior to the first release, we spent more than two years monitoring mosquitoes and working with the communities in our field trial sites.

Following encouraging small-scale trials, EDP began large-scale deployments in Brazil in 2017. During the next two years, the project will reach more than 2.5 million people across the municipalities of Rio de Janeiro and Niteroi.

Eliminate Dengue Brazil has been brought to Brazil by The Oswaldo Cruz Foundation (Fiocruz), under the guidance of the Ministry of Health.
