A recent death in Florida has been linked to Vibrio vulnificus, a bacterium that can cause severe illness and tissue degradation. The pathogen thrives in warm coastal waters and can enter the body through open wounds or the consumption of raw shellfish.
Once in the body, Vibrio vulnificus can infect open wounds, leading to a condition known as necrotizing fasciitis. This occurs when the bacteria degrade and kill tissue under the skin, along the fascia. In severe cases, necrotizing fasciitis can necessitate amputation or prove fatal. Infected wounds are often described as extremely hot and painful, though the initial signs may be difficult to see as the infection progresses beneath the skin.
Ingesting the bacteria can lead to gastrointestinal symptoms such as diarrhea, vomiting, and stomach cramps, mirroring food poisoning. For individuals with compromised immune systems, the infection can spread to the bloodstream, becoming life-threatening. The Centers for Disease Control and Prevention (CDC) indicates that wound infections with Vibrio vulnificus tend to be more lethal. People who are elderly or have underlying medical conditions, including liver disease, diabetes, or cancer, face a higher risk of developing severe illness.
