Florida Battles Largest Dengue Surge in Decades

Florida is confronting its most significant dengue fever outbreak in decades, with state health officials confirming 485 locally acquired cases this year. The majority of these infections, around 95%, are concentrated in the Tampa Bay area. This surge led to emergency declarations in Hillsborough, Pasco, and Pinellas counties in late September, enabling swifter response measures.

The Aedes mosquitoes responsible for transmitting dengue are active during the day and thrive in humid residential environments. Public health officials emphasize the importance of eliminating standing water in yards, as these mosquitoes require minimal water to breed. Residents are urged to take precautions such as applying EPA-registered repellents and covering exposed skin.

While most dengue infections are mild and resolve within two weeks, severe cases can develop rapidly and require immediate emergency medical care. The current outbreak is separate from over 300 travel-associated dengue cases reported in Florida this year, highlighting a significant local transmission challenge.
