5 Dead in Louisiana After Contracting Flesh-Eating Vibrio Bacteria
Five people in Louisiana have died this year after contracting Vibrio vulnificus, a potentially deadly bacterium found naturally in warm coastal and brackish waters, state health officials said.
Louisiana has reported nine cases of Vibrio vulnificus so far this year, with another four people hospitalized. Every case involved a wound that had been exposed to seawater, according to health officials, and all nine patients had underlying health conditions that can raise the risk of serious illness and complications.
Health officials are urging people with open wounds to avoid saltwater and brackish water and to thoroughly wash any wound with soap after possible exposure. Brackish water is a mixture of fresh and salt water, often found where rivers meet the ocean.
Vibrio bacteria can infect people in multiple ways. In addition to entering the body through an open wound exposed to contaminated water, the bacteria can be contracted by eating raw or undercooked shellfish, particularly oysters. Officials are also advising people to fully cook seafood and keep cooked seafood away from raw seafood and its juices.
Signs of a Vibrio wound infection can include fever, pain, redness, swelling, discoloration or fluid discharge around the affected area, according to the CDC.
The bacteria are most prevalent between May and October, when coastal waters are warmer. But scientists have increasingly detected Vibrio in areas where water temperatures were once considered too cold for the pathogen to thrive.
Researchers in New York, for example, said in April that they had detected Vibrio vulnificus in several bodies of water off the coast of Long Island. Previous cases have also been reported around Long Island Sound, a development scientists have linked, in part, to warming waters driven by climate change.
Farther south, Maryland health officials have also urged swimmers to use caution in the Chesapeake Bay after more than two dozen cases were confirmed in the state this year.
Researchers with the U.S. Department of Agriculture and the Environmental Protection Agency have estimated that the number of Vibrio infections in the United States could increase by 50 percent by 2090 compared with 1995 levels as sea temperatures continue to rise.
Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine, told CBS News the bacteria are appearing progressively farther north as the climate warms.
“With every year now, because of climate change, we’re seeing it higher and higher in more northerly latitudes.”
Louisiana is not the only state reporting infections this year. Florida has recorded 14 Vibrio vulnificus cases, including two deaths, according to the Florida Department of Health. One person died in Marion County in Central Florida, while another death was reported in Palm Beach.
Florida officials have also warned that hurricanes and other major storms can increase the risk of exposure by pushing brackish coastal water farther inland.
The state experienced an especially deadly year for Vibrio vulnificus in 2024, when Hurricanes Helene and Milton struck the region. Florida reported 19 deaths from the bacterium that year.
The dangers of wound exposure were illustrated by the case of Summerlin Skipworth, who told CBS News she injured her foot on rocks while visiting Orange Beach, Alabama, over Labor Day weekend last year and contracted the infection. Within several days, the pain became severe enough that she went to an emergency room, where she tested positive for Vibrio vulnificus.
“It felt like somebody poured gasoline on my foot and lit it on fire.”
Skipworth underwent emergency surgery and was released shortly afterward. Doctors credited early detection with helping her recover. “An infection never crossed my mind,” she said. “I just knew I had pain in my foot.”
Vibrio vulnificus is among roughly a dozen Vibrio species capable of causing an illness known as vibriosis, according to the Centers for Disease Control and Prevention. The CDC estimates that approximately 80,000 cases of vibriosis occur in the United States each year.
Vibrio vulnificus infections can be particularly dangerous. About one in five people infected with the bacterium die, according to the CDC, sometimes within just one or two days after becoming sick.
Symptoms can include diarrhea, stomach cramps, nausea, vomiting and fever. In more severe cases, the infection can spread into the bloodstream, potentially causing low blood pressure and blistering skin lesions.
Hotez said people with underlying risk factors should be particularly careful about entering coastal waters with cuts or abrasions.
“If you have those risk factors, and if you have an open wound or abrasion in your skin, you do not want to go swimming in brackish waters along the Gulf Coast and the Atlantic Seaboard,” he said.
The growing geographic range of Vibrio has become a concern as ocean temperatures rise. Although the bacteria have long been associated with warmer coastal areas, infections and detections in places such as the Northeast suggest that the conditions favorable to Vibrio are expanding beyond their traditional range.
