In anticipation of Hurricane Milton’s heavy rains and flooding, the Florida Department of Health is warning residents about the heightened risk of Vibrio infections, particularly Vibrio vulnificus, a potentially life-threatening bacteria that thrives in coastal waters. The bacteria can cause serious illness if ingested or if it enters the body through open wounds.
Floodwaters, especially in brackish or saltwater areas, can have higher concentrations of Vibrio, raising the risk of infection. Individuals with weakened immune systems, liver disease, or open wounds are especially vulnerable. Symptoms of Vibrio vulnificus infection include diarrhea, vomiting, abdominal pain, fever, chills, and in severe cases, confusion, fast heart rate, and disorientation. The infection can rapidly become critical, requiring intensive care or even leading to limb amputation, and has a high mortality rate, with 1 in 5 infected individuals dying within days.
To reduce the risk, the Health Department urges people to avoid wading or swimming in floodwaters, cover open wounds with waterproof bandages, and thoroughly wash any skin exposed to floodwaters. Immediate medical attention is advised if symptoms develop after exposure to floodwaters.
