Dengue Worldwide

Dengue can affect millions of people around the world every year, and cases are increasing dramatically.

One projection estimates that more than six billion people (60% of the world’s population) could be at risk of dengue infection by 2080.

The World Health Organization estimates that 3.9 billion people are at risk of catching dengue, globally. That’s 50% of the world’s population.

Dengue is the most rapidly spreading mosquito-borne disease in the world, with 30 times as many cases seen today compared to 50 years ago.

Dengue cases are increasing because of human activity.  

Scientists think mosquitoes and primates, such as monkeys and apes, passed a dengue-like virus back and forth in Asia and Africa long before it evolved into the infection that affects millions of people today.
