Five Louisiana residents die from flesh-eating bacteria infections

In 2026, Louisiana experienced a concerning rise in infections caused by the flesh-eating bacteria Vibrio vulnificus, with five out of nine reported cases resulting in fatalities. This alarming trend reflects a significant increase in both the infection rate and severity compared to the previous decade, where the state averaged seven cases and one death annually. The Louisiana Department of Health has issued advisories to raise awareness about the dangers posed by this bacteria, which thrives in warm coastal waters, particularly from May to October when temperatures are highest.

Vibrio vulnificus infections can occur through exposure of open wounds to brackish or salt water, or by consuming undercooked seafood, especially oysters. The symptoms of infection can range from gastrointestinal distress to severe wound infections and blood poisoning. The health department has emphasized that individuals with underlying health conditions, such as HIV, cancer, or thalassemia, are at a heightened risk for severe or fatal outcomes. The agency noted that approximately one in five people infected with Vibrio vulnificus may die, often within a short period after falling ill.
