A rare and deadly flesh-eating bacteria, Vibrio vulnificus, has surged in infections in Florida, claiming five lives this year alone. As of 2025, there have been 20 confirmed cases of the infection, with one new case reported in Martin County.
Most infections begin with consuming raw or undercooked shellfish, especially oysters. The Centers for Disease Control and Prevention (CDC) warns that open wounds can become infected if exposed to contaminated saltwater.
Extreme weather events like coastal floods, hurricanes, and storm surges also increase the risk of Vibrio vulnificus infections, particularly for older adults and those with underlying health issues.
The Florida Department of Health reports that while these infections are rare, they can lead to severe complications. Symptoms include diarrhea, stomach cramping, nausea, vomiting, fever, and chills. Antibiotics can treat most cases, but surgery may be necessary in serious instances.
Rapid diagnosis is crucial for effective treatment and recovery. Those with strong immune systems are at low risk of developing serious complications. In 2024, Florida had a total of 82 confirmed infections with 19 deaths.
Vibrio vulnificus bacteria cause around 80,000 illnesses annually in the US, with a mortality rate of about 20% among those infected, often leading to death within one to two days after symptoms arise.
