Brazil | World Mosquito Program Skip to main content

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

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.

Release areas

In Brazil, we are working across the municipalities of Rio de Janeiro and Niterói where we expect to reach approximately 1.2 million people in 2019.

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.

Dengue is a very dangerous disease. It kills! My greatest hope is that we no longer have these diseases here, and that this project is spread throughout Brazil and, perhaps, around the world.
