"Rising temperatures have caused as many as 4.6 million extra dengue cases each year, and will cause many more by 2050, a new study finds." 

"Global cases of flu-like dengue fever reached a historic high last year, with over 14.6 million cases and more than 12,000 related deaths reported to the World Health Organization. 

Global warming is driving up those infection numbers in a big way, a new study suggests.

Transmitted by the cold-blooded Aedes aegypti mosquito, the dengue virus is common across tropical and subtropical regions in Asia and the Americas.

Nearly one-fifth of cases in recent decades can be directly attributed to rising temperatures, researchers at Stanford, Harvard and Arizona State universities and the National Bureau of Economic Research found."
