(NewsNation) — Four people have died from a flesh-eating bacteria in Florida this year, with a total of 11 cases reported, according to the Florida Health Department.
Vibrio vulnificus is a rare infection that usually exists in warm seawater and can be contracted if someone has an open wound in seawater or by eating raw shellfish, particularly oysters.
Preventions for the immunocompromised include wearing adequate foot protection around rocks and shells on the beach to avoid cuts and injury and to avoid eating raw oysters and shellfish.
The department says it can cause skin infections and ulcers but is unlikely to cause more than mild disease for healthy persons.
Vibrio vulnificus can invade the bloodstream of individuals who are immunocompromised and lead to fever, chills and other life-threatening conditions. Approximately 50% of bloodstream infections caused by Vibrio vulnificus are fatal.
Amputation may be needed if the wounds are severe enough. Antibiotics can help improve the prospects of survival.
In 2024, 19 people died from the bacteria in Florida and 11 in 2023. The higher number of deaths last year was due to Hurricane Helene.
