All of this year’s reported cases were linked to wounds exposed to seawater, and all patients had underlying health conditions, the department added
Vibrio bacteria naturally live in coastal waters, according to the Centers for Disease Control and Prevention, and is more common in the summer when water temperatures rise
People can contract the infection by eating raw or undercooked shellfish, particularly oysters, or when an open wound comes into contact with coastal waters, the CDC says
About 1 in 5 people with a Vibrio vulnificus infection die, according to the agency
While anyone can be infected, the Louisiana Department of Health said those most at risk include people with liver disease, cancer, diabetes, HIV or thalassemia; people undergoing immune-suppressing treatment; people taking medication that reduces stomach acid; and people who recently had stomach surgery
