The number of Vibrio vulnificus cases and deaths this year easily exceeded 2019’s numbers, according to the most recent data from the Florida Department of Health (DOH).
With two weeks left in the year, DOH reports 36 cases and seven deaths, up from 27 cases and 2 deaths reported last year.
Hernando County saw the most cases this year with six, followed by Brevard and Broward counties with 4 each.
The seven deaths were from Broward, Duval, Hernando, Lake, Martin, Pasco and Santa Rosa counties.
Vibrio vulnificus can cause disease in those who eat contaminated seafood or have an open wound that is exposed to warm seawater containing the bacteria. Ingestion of Vibrio vulnificus can cause vomiting, diarrhea and abdominal pain. Vibrio vulnificus can also cause an infection of the skin when open wounds are exposed to warm seawater; these infections may lead to skin breakdown and ulcers.
Healthy individuals typically develop a mild disease; however, Vibrio vulnificus infections can be a serious concern for people who have weakened immune systems, particularly those with chronic liver disease.
The bacterium can invade the bloodstream, causing a severe and life-threatening illness with symptoms like fever, chills, decreased blood pressure (septic shock) and blistering skin lesions. Vibrio vulnificus bloodstream infections are fatal about 50 percent of the time. A recent study showed that people with these pre-existing medical conditions were 80 times more likely to develop Vibrio vulnificus bloodstream infections than healthy people.
