Public health officials report a seasonal rise in Vibrio vulnificus—a warm-water coastal bacterium often called "flesh-eating bacteria"—with over 25 combined cases and multiple deaths recorded across Gulf Coast states like Florida and Louisiana. The bacteria thrive in warm, brackish marine waters and enter the body via open cuts or raw seafood.
How Infection Happens
- Warm Seawater: The bacteria multiply quickly in salt and brackish water when temperatures rise between May and October.
- Open Wounds: Cuts, scrapes, new tattoos, or piercings exposed to coastal water allow the bacteria to enter the skin and bloodstream.
- Consuming Seafood: Eating raw or undercooked shellfish, especially oysters, can lead to severe systemic illness.
Warning Signs and Symptoms
- Initial Signs: Sudden, intense pain, redness, swelling, or warmth around a skin break or wound.
- Rapid Progression: Fever, chills, blistering skin lesions, black spots, or fluid-filled blisters.
- High Risk Groups: People with chronic liver disease, diabetes, or weakened immune systems face the highest risk of severe complications or death.
Prevention and Safety Steps
- Cover Wounds: Keep open cuts, scratches, or sores completely covered with a waterproof bandage if visiting coastal or brackish waters.
- Avoid Exposure: Stay out of warm coastal water if you have a deep or active wound.
- Cook Seafood: Avoid eating raw or undercooked oysters and shellfish.
- Seek Immediate Care: If severe pain, swelling, or redness develops rapidly around a minor cut, visit an emergency room immediately; treatment requires urgent antibiotics and surgical removal of damaged tissue.
