Vibrio vulnificus is a bacteria that dwells in warm, brackish saltwater.
Although infections are uncommon, Florida sees several instances of vibrio each year. So far this year, the Florida Department of Health (FDOH) has reported 26 instances across the state.
Five persons were killed in the Tampa Bay area. Hillsborough County recorded two deaths, while Pasco, Polk, and Sarasota counties each reported one.
Vibrio can enter the body through open wounds or cuts, according to Dr. Margaret Cancio, an infectious disease expert with AdventHealth. One significant symptom to look for, according to her, is a wound infection that is bright red and has blisters.
If you develop these wounds after being in the water, getting to a doctor as soon as possible is important.
“The most important thing to avoid dying is to get to medical care quickly. We do have antibiotics, and if you get good care, your chances of dying decrease,” said Cancio.
Cancio also said you should avoid going into the water if you have fresh cuts or scrapes. You can also get vibrio by eating raw shellfish, like oysters.
Last year, FDOH reported 74 cases of vibrio statewide. Most of those were in Lee County following Hurricane Ian.
