Global Dengue Cases Reach Record High in 2024 Amid Rising Risks
Dengue, a viral infection transmitted by Aedes mosquitoes, has seen a dramatic global increase in cases, with over 14.6 million reported in 2024, according to the World Health Organization (WHO). The disease, which is endemic in over 100 countries, is particularly prevalent in tropical and subtropical regions. Symptoms range from mild fever and rash to severe complications, including internal bleeding and organ damage. The Americas accounted for the majority of cases, with over 13 million infections reported. Factors such as climate change, urbanization, and limited healthcare infrastructure are contributing to the spread of the disease. WHO highlights that early detection and proper medical care can significantly reduce fatality rates, but there is no specific treatment for dengue. Prevention efforts focus on vector control and personal protection against mosquito bites.
