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.

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.
