Florida’s Department of Health confirmed the state’s first Vibrio vulnificus death in 2026, an 80‑84‑year‑old resident of Palm Beach County. The case brings the 2026 tally to 12 confirmed infections across nine counties (Palm Beach, Miami‑Dade, Lee, Bay, Hillsborough, Marion, Okaloosa, Polk, St. Johns). Officials say the infections appear isolated with no common source, and the bacterium typically enters through open wounds or consumption of raw shellfish. CDC estimates a 20‑25 % fatality rate for severe cases, emphasizing higher risk for older adults and those with liver disease, diabetes, kidney disease, or compromised immunity. Historical data show 33 cases and five deaths in 2025 and a larger surge in 2024 with 82 cases and 19 deaths, the latter linked to Hurricane Helene’s impact on coastal waters. Health agencies continue to advise at‑risk individuals to avoid warm coastal water exposure and raw seafood during peak season, while routine recreation remains safe for the general public.

- The CDC estimates that about one in five people with a severe Vibrio vulnificus infection die. (corroborated by 4 sources)
