Dengue Cases Surge Tenfold Globally Over Last Generation

Over 5 million cases and 5,000 deaths reported this year, with the Americas hardest hit and climate change a key factor.

Dengue cases globally have increased tenfold over the last generation, with a record 5.2 million cases reported in 2019.
Climate change and the growing spread of virus-carrying mosquitoes are partly to blame for the rise in dengue cases, which remain mostly prevalent in the Americas.
More than 5 million cases and over 5,000 dengue-related deaths were reported this year.
Weaker health systems and poor surveillance have also contributed to the rise in dengue cases.
There are two licensed vaccines for dengue, but no specific treatments for the virus once someone becomes infected.
