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.
