The surge in dengue cases poses significant health risks, particularly in tropical and subtropical regions. Vulnerable populations, including those in urban and semi-urban areas, are at heightened risk due to the prevalence of Aedes mosquitoes. Severe dengue can lead to life-threatening complications, especially for individuals with prior infections. The disease's expansion into previously unaffected areas, such as Europe, underscores the growing global threat. Overburdened healthcare systems in affected regions face challenges in managing outbreaks, while climate change and urbanization further exacerbate the spread.
