Floridians are being advised to avoid floodwaters in the aftermath of Hurricane Idalia due to the potential presence of flesh-eating bacteria. The destruction caused by the hurricane has raised concerns about an increase in infections caused by Vibrio vulnificus, a bacteria that typically resides in warm seawater but can be carried inland by storms. Data suggests that the incidence of Vibrio infections more than doubles after hurricanes. The Centers for Disease Control and Prevention (CDC) has issued a nationwide alert for Vibrio infections, including North Carolina where beachgoers have been warned about the bacteria. The Florida Department of Health has urged residents to be cautious of Vibrio vulnificus in floodwaters. The bacteria has been detected as far north as Alaska and poses the most risk to individuals with weakened immune systems, particularly those with chronic liver disease or who are taking immunosuppressive medications. Health officials emphasize the importance of taking the threat seriously and treating the bacteria with caution, comparing it to encounters with alligators and rattlesnakes. Vibrio vulnificus thrives in warm coastal and brackish waters, predominantly along the Florida coastline. After hurricanes, stagnant pools of water are left behind, providing an environment for the bacteria to grow. These pools can contain raw sewage and become heated during the day, increasing the risk of infection. Symptoms of Vibrio infections include redness and swelling around the site of the infection, which can progress to tissue death and blood infection if left untreated. Antibiotics should be administered promptly to prevent the infection from spreading. The incidence of Vibrio infections rises after hurricanes due to increased exposure to the bacteria in stagnant pools. In Florida, there was a significant increase in Vibrio deaths and cases following Hurricane Ian. The spike in infections highlights the need for caution and awareness during hurricane recovery efforts. Vibrio vulnificus is a year-round risk for millions of Americans, particularly those who swim in warm brackish water along coastlines. Rising sea temperatures have allowed the bacteria to expand its range, reaching new areas and moving northward. This year, Vibrio infections have been reported as far as New York and Connecticut. Scientists predict that by 2040, Vibrio vulnificus will have spread to every state in the US. It is estimated that around 30% of people who develop a Vibrio infection die from the disease, with those with weakened immune systems at higher risk.
