Florida's Vibrio cases hit 25 with five deaths — including Broward and Palm Beach; stay out of floodwater with open wounds

Florida has recorded 25 Vibrio vulnificus infections and five deaths in 2026, according to the Florida Department of Health's tracking page, with data current through Oct. 1. The death toll already equals the state's total for all of 2025 (33 cases, five deaths), with nearly three months of the year still to go. The five deaths were reported in Broward, Palm Beach, Pinellas, Marion, and Bay counties; cases are spread across 16 counties, with no county reporting more than three.

Vibrio vulnificus is a bacterium that lives naturally in warm salt and brackish coastal waters. Infection happens mainly two ways: through an open wound exposed to coastal or floodwater, or by eating raw or undercooked shellfish, especially oysters. It does not spread person to person. Florida logged 33 cases in 2025 and 82 cases with 19 deaths in 2024, a spike the health department linked to floodwaters after Hurricanes Helene and Milton.

The October 8, 2026 state update lands just after Hurricane Isaias swept through Florida, when storm cleanup means cuts, scrapes, and hours in brackish water. Per the CDC, severe illness is more likely in people with liver disease, cancer, diabetes, HIV, or thalassemia, people on treatments that weaken the immune system, and people on stomach-acid-reducing medicine or with recent stomach surgery.

Practical steps from health officials: cover wounds with waterproof bandages, wear protective footwear during cleanup, and wash with soap and clean water after contact with floodwater. Warning signs include redness, swelling, warmth around a wound, fever, and chills; the CDC advises people with signs of a Vibrio wound or bloodstream infection to seek emergency care immediately and not wait.

Why it matters: This is not just a Gulf Coast problem — two of this year's five Florida deaths were in Broward and Palm Beach counties, and post-hurricane cleanup is exactly when infection risk rises. If you have diabetes or any immune-weakening condition and spend time around South Florida's waterways, cover every cut and take spreading redness or fever seriously.
