Health experts are warning that the risk of contracting Vibrio vulnificus, a potentially deadly Flesh-Eating Bacteria found in warm coastal waters, is increasing as ocean temperatures climb and storms intensify. The Centers for Disease Control and Prevention (CDC) reports that one in five infected individuals die as the infection spreads quickly through the body.
The growing threat is not confined to the Gulf Coast. Researchers say warming waters are expanding the bacteria’s reach to areas that historically have been unaffected, putting more people at risk.
Survivor’s Story Highlights Dangers
Lifelong boat captain George Billiris of Tarpon Springs, Florida, knows firsthand how quickly the bacteria can take hold. In July 2019, while fishing with his grandson, Billiris waded into the Gulf waters with a minor scab on his leg. Within hours, he experienced chills, fever, swelling, and a burning sensation.
“I started to get chills, feverish, my leg was swelling, burning,” Billiris recalled. Doctors at the hospital used a marker to track how rapidly the infection spread. After three weeks of treatment, he survived without losing his leg—a fate that is not uncommon for severe cases.
Billiris considers himself lucky, noting that many delay seeking treatment because they don’t recognize the symptoms early enough. “A lot of people waited because they didn’t know,” he said.
Climate Change Expands Flesh-Eating Bacteria’s Range
Dr. Valerie Harwood, a microbiologist at the University of South Florida, explained that Vibrio vulnificus thrives in warm, brackish water. Rising sea surface temperatures, fueled by climate change, are allowing the bacteria to survive and multiply in areas farther north than ever before.
“With warming waters, we are seeing cases further north,” Harwood said. “In recent years, infections have been reported in the Carolinas, Connecticut, and even New York.”
In addition to higher temperatures, hurricane season poses an added danger. Strong storms churn up coastal waters, creating conditions favorable for the Flesh-Eating Bacteria and increasing the likelihood of human exposure.
So far this year, Louisiana has reported 17 cases, Florida 16 cases with five deaths, and North Carolina seven cases. The CDC warns that these numbers could rise if ocean temperatures continue to increase.
How the Flesh-Eating Bacteria Spreads?
People typically contract Vibrio vulnificus when the bacteria enter the body through cuts or open wounds during contact with warm coastal waters. Consuming raw or undercooked seafood—especially oysters—can also transmit the infection.
Once inside the body, the bacteria can cause severe wound infections, septicemia, and, in extreme cases, tissue death requiring amputation.
The CDC advises people with open wounds to avoid warm, brackish waters, particularly in summer and during hurricane season. They also recommend thoroughly cooking shellfish and wearing protective gloves when handling raw seafood.
Staying Safe in Warming Waters
Despite his near-death experience, Billiris continues to sail daily, but with more caution. He hopes others will learn from his ordeal and seek medical help at the first sign of infection.
Early symptoms include redness, swelling, intense pain, fever, and chills. Prompt treatment with antibiotics, and in some cases surgery, can be life-saving.
As climate change continues to warm oceans, experts emphasize public awareness and preventative measures. “Recognizing the symptoms early and knowing when to get medical attention can make the difference between recovery and tragedy,” Harwood said.
With ocean temperatures expected to keep rising, the threat posed by Vibrio vulnificus may soon become a reality for more communities across the U.S. coast.
