Louisiana warns of flesh-eating bacteria surge in coastal waters

Louisiana health officials are issuing urgent warnings to beachgoers, urging them to take precautions against a concerning rise in infections caused by Vibrio vulnificus, a potentially deadly flesh-eating bacteria found in coastal waters. The state has confirmed nine cases of Vibrio vulnificus infections so far this year, a notable increase from the average of seven cases reported over the previous decade. Tragically, five of these nine patients have died.

During the same period over the previous 10 years, Louisiana reported an average of seven cases and one death. All nine cases reported this year were associated with wounds exposed to seawater, and all patients had underlying health conditions.

According to the Louisiana Department of Health (LDH), all nine individuals who contracted the infection were hospitalized. The department emphasized that these cases were linked to wounds exposed to seawater and that all patients had pre-existing health conditions. Vibrio bacteria occur naturally in warm coastal waters, with concentrations peaking between May and October when water temperatures are higher.

Infection can occur through an open wound's exposure to brackish or salt water, or by consuming raw or undercooked seafood, particularly oysters. Vibrio infections can lead to severe gastrointestinal illness, dangerous wound infections, or life-threatening blood poisoning. The LDH noted that approximately one in five people infected with Vibrio vulnificus die, sometimes within 24 to 48 hours of becoming ill.

Infection can occur when an open wound is exposed to brackish or salt water or when a person eats raw or undercooked seafood, particularly oysters. Vibrio infection can result in gastrointestinal illness, wound infection, or blood poisoning (bloodstream infection).

While anyone can contract a Vibrio infection, individuals with liver disease, cancer, diabetes, HIV, or thalassemia face the highest risk of severe complications. The bacteria can enter the body through unhealed cuts, scrapes, recent piercings, tattoos, or surgical incisions. People undergoing immune-suppressing treatments, taking medication to reduce stomach acid, or who have recently had stomach surgery are also at increased risk. Symptoms of a Vibrio wound infection include fever, redness, swelling, pain, warmth around the wound, skin discoloration, and discharge. The LDH strongly advises anyone experiencing these symptoms after a wound has been exposed to salt water to seek immediate medical attention.

About one in five people with a vibrio vulnificus infection dies, sometimes within a day or two of becoming ill.
