All nine patients were hospitalized, and five died
During the same period over the previous 10 years, Louisiana reported an average of seven cases and one death
Vibrio bacteria are found naturally in warm coastal waters. The number of cases tend to increase from May to October, when water temperatures are warmer
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
People with severe infections may require intensive care or limb amputation. About one in five people with Vibrio vulnificus infection die, sometimes within a day or two of becoming ill
Seek medical care immediately if a wound exposed to brackish or salt water becomes red, swollen, painful, warm, or discolored. Tell the health care provider about the water exposure
Signs of a bloodstream infection include fever, chills, dangerously low blood pressure, and blistering skin lesions
