The Florida Department of Health is advising residents and visitors to avoid floodwaters due to the risk of infection from Vibrio bacteria, including Vibrio vulnificus, following heavy rainfall and flooding expected from Hurricane Milton. According to the department, these bacteria are commonly found in warm coastal waters and can cause illness when ingested or when open wounds are exposed to contaminated water. The concentration of Vibrio may increase in brackish and saltwater environments after significant rain.
The department notes that people with compromised immune systems, liver disease, or open wounds are at higher risk for serious infection. Symptoms of Vibrio vulnificus can include diarrhea, vomiting, abdominal pain, fever, chills, rapid heart rate, confusion, or disorientation.
"Seek medical attention immediately if you experience symptoms associated with Vibrio vulnificus, especially after exposure to floodwaters," the department advised.
Precautions recommended by health officials include avoiding swimming or wading in floodwaters and covering open cuts or wounds with waterproof bandages if there is a chance they could come into contact with contaminated water. Washing skin and any open cuts thoroughly with soap and clean water after exposure is also encouraged.
The Florida Department of Health continues to monitor health risks related to Hurricane Milton. Additional information about emergency preparedness and a factsheet on Vibrio vulnificus can be found at FloridaHealth.gov/Emergency or by contacting local county health departments.
The agency is accredited by the Public Health Accreditation Board and works through state, county, and community efforts to protect public health across Florida.
