Dengue Cases Surge Globally Amid Climate Impact

Dengue fever continues to pose a significant health challenge globally, with Bangladesh reporting 545 deaths this year as of mid-December, amid a total of 98,188 cases since January. The Americas and the Caribbean are also experiencing a severe outbreak, with 12.6 million suspected cases and over 7,700 deaths, marking a more than 200% increase compared to the previous year. Brazil leads the region with over 10 million cases, followed by Argentina and Mexico, while Guyana leads in the Caribbean. The surge in cases is attributed to climate change, contributing to expanded mosquito habitats, and the reemergence of dengue serotype 3 in parts of Central America and the Caribbean. Efforts to control the outbreak include public health advisories and fines for properties fostering mosquito breeding. While vaccines are available in some countries, prevention through eliminating mosquito habitats remains the recommended strategy.
