The U.N. health agency said Friday that reported cases of dengue globally increased tenfold over the last generation, with climate change and the growing spread of virus-carrying mosquitoes partly to blame for transmission that remains mostly prevalent in the Americas.
The World Health Organization said reported cases soared to a record 5.2 million in 2019, up from 500,000 in 2000, across 129 countries worldwide, figures that likely understate the actual toll.
