The rapid increase in dengue cases poses significant health risks, particularly in tropical and subtropical regions. Vulnerable populations, including children, the elderly, and those with pre-existing conditions, are at higher risk of severe illness and death. The disease's spread to new areas, including parts of Europe, highlights the growing global threat. Overburdened healthcare systems in affected regions face challenges in managing the surge in cases, leading to delayed treatment and higher fatality rates. The economic impact is also substantial, with increased healthcare costs and loss of productivity.
