"Yellow Fever Resurgence: Experts Warn of Spreading Cases and Lack of Preparedness"

Dengue fever, a mosquito-borne viral illness, is spreading to new places around the world, including areas where it was previously unheard of. The Aedes aegypti mosquito, which is driving many of the current outbreaks, has adapted to thrive in urban areas and is spreading due to trade routes and climate change. Dengue can cause severe symptoms such as joint pain, high fever, and organ failure, with a mortality rate of up to 15% when left untreated. Factors such as urbanization and lack of mosquito control contribute to the spread of the disease. While there is no specific treatment for dengue, efforts are being made to develop vaccines and control measures, such as the use of Wolbachia bacteria to prevent the transmission of the virus.
