Locally transmitted dengue cases have reached record levels in Florida, marking one of the state’s worst outbreaks in decades.  

Dengue fever prompts Hillsborough to extend state of local emergency

Because nearby areas have reported dengue, there is a risk it could be introduced here.

Based on the Florida Arbovirus Surveillance report for week 38 (September 20–26), 2026, 252 locally acquired dengue cases and 20 mosquito pools were reported across seven counties.

Indian River County has not reported local dengue transmission as of 10/5/26.

Anyone who lives in or travels to an area with dengue risk can be infected. Before you travel, check specific travel guidance to help you plan and pack.

If you must travel, protect yourself by:

• Wearing loose clothing, long-sleeved shirts, and long pants
• Using an EPA-approved repellent with oil of lemon eucalyptus, picaridin, IR3535, or DEET
• Reapplying repellent as directed if you are outdoors for long periods

Mosquitoes that carry dengue can bite day or night, so use caution whenever you are outdoors.
