Flesh-eating bacteria infections caused by Vibrio vulnificus are prompting urgent health warnings across Gulf and Eastern coastal states, where at least seven deaths have been confirmed this season according to officials cited by CBS News. The Centers for Disease Control and Prevention reports that about one in five people who contract the severe necrotizing fasciitis infection die, often within a day or two of noticeable symptoms.
Where Vibrio Vulnificus Cases Are Surging Along U.S. Coasts
State health departments have documented dozens of bacterial infections this season, highlighting a geographic spread that now reaches northern waters. According to state figures, Louisiana has recorded nine cases with five fatalities, while Florida logged 14 cases and two deaths. Alabama has documented 16 Vibrio infections including one death, Mississippi recorded three cases, and Maryland reported confirmed cases ranging from 29 to 72 depending on the reporting period, though with no deaths reported in that state.

Researchers note that these infections are no longer confined to traditional southern hotspots. According to Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine (cited by CBS News), warming waters driven by climate change have allowed the bacteria to spread to more northerly latitudes, with detections as far north as New York and warnings issued for the Chesapeake Bay in Maryland. A 2023 study found that reported cases in the eastern United States increased eightfold between 1988 and 2018.
How Beachgoers Contract Necrotizing Fasciitis
Vibrio vulnificus thrives in warm salt or brackish waters—areas where the ocean mixes with freshwater—typically between May and October, according to microbiological research from the Indiana University School of Medicine (via Yahoo Health). Swimmers, fishers, and waders contract the bacteria when it enters the body through open wounds, cuts, or sores. People can also fall ill by handling raw or undercooked seafood, such as oysters, or by exposing a wound to tainted seafood juices.
Pro Tip: Health departments recommend avoiding salt or brackish water entirely if you have an open cut. If exposure is unavoidable, cover the wound with a waterproof bandage and thoroughly wash any exposed skin immediately after leaving the water.
Real-life accounts underscore how fast the infection can strike. Summerlin Skipworth, a survivor interviewed by CBS News, contracted the bacteria after scraping her foot against rocks at Alabama’s Orange Beach over Labor Day weekend. Within days, she experienced intense pain that she described as feeling “like somebody poured gasoline on my foot and lit it on fire.” Skipworth underwent emergency surgery and recovered thanks to early detection by medical staff.
Who Faces the Highest Risk of Severe Illness?
While anyone can contract a Vibrio infection, certain underlying medical conditions dramatically increase vulnerability to severe tissue destruction and bloodstream invasion. According to the CDC and Dr. Peter Hotez (cited by CBS News), high-risk individuals include those with:

- Liver disease
- Cancer
- Diabetes
- HIV
- Thalassemia, a blood disorder
- Patients undergoing immune-suppressing therapy or taking stomach acid-reducing medications
For these populations, exposure to brackish water with an open abrasion can rapidly lead to life-threatening complications.
Recognizing Symptoms and Seeking Urgent Treatment
Recognizing the early warning signs of a Vibrio vulnificus wound infection is critical because the disease progresses rapidly. According to the CDC and infectious disease specialists, symptoms include fever, chills, nausea, vomiting, stomach cramps, and intense pain, redness, swelling, or warmth around the injury site. Infected wounds can quickly develop blisters, ulcers, skin discoloration, and fluid discharge. Clinicians treat the infection by administering intravenous antibiotics directly into the bloodstream alongside surgical removal of dead tissue.
Did You Know? Extreme weather events also impact infection rates. Florida recorded a record high of 82 cases in 2024, with many arriving in the aftermath of Hurricane Helene due to increased contact with storm surges and coastal floodwaters.
Frequently Asked Questions About Flesh-Eating Bacteria
What causes flesh-eating bacteria infections?
Necrotizing fasciitis can be caused by several bacteria, most commonly group A Streptococcus, but Vibrio vulnificus is a primary culprit associated with warm coastal seawater and raw shellfish.
Can you get Vibrio vulnificus from eating seafood?
Yes. Ingesting raw or undercooked seafood, particularly oysters harvested from warm coastal waters, can cause gastrointestinal illness and, in vulnerable people, severe systemic infection.
What should I do if I cut myself at the beach?
Wash any cuts exposed to seawater or raw seafood immediately with soap and clean water, and seek medical attention right away if you develop worsening pain, redness, or swelling.
Are flesh-eating bacteria cases increasing?
Yes. Studies and public health records show that warming ocean temperatures driven by climate change are expanding the geographic range of Vibrio vulnificus northward along the U.S. East Coast.
