Dengue incidence has increased 30‐fold in the last five decades 5. Currently, dengue is endemic in 128 countries, most of them developing nations, affecting approximately 3.97 billion people annually 6. The incidence of dengue increased greatly over the past two decades in Brazil, affecting all regions of the country, except the South 7. Forty years after its discovery, ZIKV reemerged during a 2007 outbreak on Yap Island in Micronesia, continued in 2013 in French Polynesia 8, 9, 10, and in 2014 moved to multiple Pacific islands. At the end of that period, it was introduced to South America 11, 12, 13, 14, 15. In Brazil, the first reports of suspected cases occurred in the Northeast, with a peak during the first quarter of 2015, but it was only confirmed in April 2015. The epidemic continued spreading in May 2016. Since then, autochthonous transmission of ZIKV had been reported in 42 countries and territories in the Region of the Americas 11, 13, 16, 17. Due to lack of reliable official data, Brazilian Ministry of Health estimated the number of cases based on reports of attack rates from other countries.
