3.5 million Dengue cases reported in Americas, tripling from last year, prompting health emergencies in some countries. Dengue, spread by mosquitoes, can cause severe symptoms and death. The outbreak has surged earlier than usual, with Brazil, Peru, Argentina, and Colombia among the most affected countries. The Pan American Health Organization (PAHO) expects this year to set a new record for dengue cases in the region. The surge in cases is attributed to rising temperatures, rapid urbanization, droughts and floods linked to climate change, and poor sanitation and health systems in some countries.
