McALLEN, Texas – Health officials are urging Gulf Coast beachgoers to protect open wounds and understand the warning signs of infection as reports of severe illness caused by Vibrio vulnificus rise during the warm-water season.
The bacteria occur naturally in warm coastal water, particularly in brackish areas where fresh and salt water mix. Most infections are reported from May through October. Louisiana had confirmed nine cases this year, including five deaths, according to health officials cited in an Associated Press report.
People can become infected when an open wound is exposed to coastal water or when they consume raw or undercooked shellfish. The Centers for Disease Control and Prevention says people with liver disease, diabetes, cancer, HIV or other conditions that weaken the immune system face a higher risk of severe illness.
Beachgoers should avoid saltwater and brackish water when they have open wounds or recent surgical sites. Waterproof bandages can reduce exposure, and cuts should be washed thoroughly with soap and clean running water after contact with coastal water.
Rapid swelling, severe pain, redness, fever, chills or skin discoloration after exposure require immediate medical attention. The illness can progress quickly, making early treatment critical.
