Since 2016, Brazil has been significantly affected by the Venezuelan refugee crisis, and currently hosts more than 88,900 Venezuelans who have fled their home country as a result of political and economic turmoil ?. The number of Venezuelans seeking protection in Brazil is rapidly increasing, and according to UNHCR, could reach 190,000 by the end of 2019.? Most Venezuelans who have fled to Brazil are being hosted in camps and host communities in the state of Roraima, which is located near the Brazil-Venezuela border.?

In 2015-2016 when Zika virus hit Latin America and the Caribbean, Brazil was most affected, reporting over a million cases by early February 2016.?
