Brazil, the host of the ongoing 2014 FIFA World Cup and the holder of the dubious title of “most dengue fever cases in the Americas”, has reported seven imported chikungunya cases during the past week, according to the Pan American Health Organization (PAHO) today.

In 2013, Brazil reported greater than 1.4 million dengue fever cases, or 63% of all dengue cases in the western hemisphere. This has prompted the continents largest country to attempt using genetically modified mosquitoes as a solution to the growing number of dengue fever cases. The same species of the Aedes mosquito transmits chikungunya, dengue fever and yellow fever.
