Dengue fever, transmitted by mosquitoes in tropical and subtropical regions, affects millions annually and has become one of the World Health Organization's top-10 global health threats. The disease causes potentially lethal flu-like symptoms and represents the fastest-growing mosquito-borne illness worldwide.
