Florida health officials confirmed a second death this year from Vibrio vulnificus, a rare bacterial infection often referred to as “flesh-eating,” on August 6. The update follows the state’s first reported fatality in 2026, bringing the total cases to 14 in the state. Louisiana, meanwhile, has reported nine cases and five deaths from the same bacteria this year, according to state health departments.
Officials in both states emphasized the urgency of seeking medical attention for wounds exposed to coastal waters. The bacteria, which thrives in warm, salty, or brackish environments, can enter the body through cuts, scrapes, or unhealed wounds. Symptoms include redness, swelling, pain, fever, chills, and discolored skin that may blister.
How the Bacteria Spreads
Vibrio vulnificus is primarily transmitted in two ways: through consumption of raw or undercooked shellfish, particularly oysters, or through direct contact with contaminated water. The bacteria are most active in coastal and brackish waters, where salt and fresh water mix, such as estuaries and lagoons. Infections are most commonly reported from May to October, with Gulf Coast states experiencing the highest incidence.
Health Advisories and Prevention
Louisiana’s health department issued a warning last week, advising beachgoers to seek immediate medical care if wounds exposed to water become infected. Officials also recommended thoroughly washing cuts and scrapes with soap and clean water after contact with coastal waters or raw seafood. The Centers for Disease Control and Prevention (CDC) echoed these precautions, noting that healthy individuals typically develop mild symptoms, but severe cases can lead to life-threatening complications.
Florida’s data shows a decline in cases compared to 2025, when the state recorded 33 cases and five deaths. However, health experts note that tropical storms and hurricanes often correlate with increased infections, as flooding can spread contaminated water inland. The bacteria’s fatality rate stands at up to 20% for Vibrio vulnificus infections, significantly higher than other Vibrio strains.
Regional Impact and Public Response
The surge in cases has prompted health departments in both states to reinforce safety guidelines for residents and visitors. While Florida and Louisiana bear the brunt of infections, other Gulf Coast states have also reported isolated cases. The CDC has not issued a national alert but continues to monitor the situation closely.
Experts attribute the rise in infections to rising ocean temperatures and increased human activity in coastal areas, which may contribute to the bacteria’s spread. Public health officials urge vigilance, particularly for individuals with compromised immune systems, chronic liver disease, or diabetes, as they are at higher risk of severe illness.
