After an absence of more than 20 years, dengue re-emerged in Brazil in 1981. Over the next 30 years, seven million cases were reported.
Today, Brazil has the greatest number of dengue cases in the world, 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.

In Brazil, we are working across the municipalities of Rio de Janeiro, Niterói, Belo Horizonte, Petrolina and Campo Grande where we expect to reach approximately 2.8 million people by 2023.
Engagement and public acceptance
Our Public Acceptance Model guides engagement, communication and issues management. No mosquitoes are released until endorsement by the local Community Reference Group.
Our dedicated team is working hard to monitor and support the projects in Rio de Janeiro and Niterói. Together with the Oswaldo Cruz Foundation (Fiocruz), the World Mosquito Program employs 64 staff in Brazil.
Partners and supporters
Our work in Brazil is made possible by the generous assistance of local partners and supporters, such as the Ministry of Health, the Oswaldo Cruz Foundation (Fiocruz), the Bill and Melinda Gates Foundation Global Grand Challenges, and the US Foundation for the National Institutes of Health.
