Dengue fever is spreading rapidly worldwide, reaching places it's never been before. Cases are emerging in surprising locations, such as France, Italy, and even California.

Dengue is a mosquito-borne viral illness known for causing agonizing joint pain, often referred to as "breakbone fever."

The Aedes aegypti mosquito is a key player in this global outbreak, originating in Africa but now thriving in urban areas due to trade and climate change.

Urbanization and climate change are driving the virus into new regions. Dr. Gabriela Paz-Bailey cites climate change and rising temperatures as factors favoring the Aedes mosquitoes.

Dengue can range from mild flu-like symptoms to severe complications, with 15% mortality when untreated. Most vulnerable are those without mosquito-protective housing.

The United States sees about 550 imported dengue cases each year. The rare locally transmitted case in Pasadena is a cause for concern.

The rise in global urbanization plays a role in the virus's spread, as people from rural areas lack immunity.

Southern China's experience serves as a warning, with a sudden surge in cases in 2014.

Currently, there's no specific treatment for dengue. Patients receive symptom management.

Although a vaccine called Dengvaxia faced issues, a new vaccine, QDENGA, recommended by the World Health Organization, offers hope.

To combat dengue, some countries employ measures like rigorous mosquito control and introducing Wolbachia-infected mosquitoes, offering potential solutions.
