Five people in Florida have died from Vibrio vulnificus, a bacteria found in raw shellfish or seawater that also killed one Long Island resident and two people in Connecticut this summer, officials have confirmed.
According to the Florida Department of Health, there have been 26 cases in the state this year. Two of the five deaths were in Hillsborough County, home of Tampa, with the remaining three deaths confirmed in Pasco, Polk and Sarasota counties.
"While rare, the Vibrio bacteria has unfortunately made it to this region and can be extraordinarily dangerous," New York Gov. Kathy Hochul said in a news release Thursday. The death in Long Island is still being investigated to determine if the bacteria was encountered in New York waters, the release added.
In Connecticut, three residents were known to have been infected with the bacteria, the state Department of Public Health said last month. All three victims were between the ages of 60 to 80 and the two deaths occurred in July, the department said.
These aren't the only cases that made headlines this year. Last month, three North Carolina residents also died from the bacteria, naturally found in warm seawater and brackish water, the Associated Press reported.
About 100 cases of Vibrio are reported in the United States each year, but because people with mild infections aren't tested, the actual number isn't known, according to the Journal of the American Medical Association. About a third of reported cases are fatal.
Some Vibrio vulnificus infections lead to necrotizing fasciitis, which the Centers for Disease Control and Prevention describes as "a severe infection in which the flesh around an open wound dies."
This kind of infection is often described as "flesh-eating bacteria," though the CDC's website notes necrotizing fasciitis can be caused by more than one type of bacteria.
How to stay safe from Vibrio vulnificus bacteria
In a statement, Hochul advised the public to "stay vigilant and take responsible precautions to keep themselves and their loved ones safe," including:
- Protecting open wounds from seawater and for those with compromised immune systems
- Avoiding raw or undercooked shellfish, which may carry the bacteria
The CDC shares additional tips to reduce your risk, including:
- Washing your hands after handing raw shellfish
- Avoid contaminating cooked shellfish with raw shellfish and its juices
- Washing wounds and cuts thoroughly if they have been exposed to seawater, raw seafood or its juices
"If you develop a skin infection, tell your medical provider if your skin has come into contact with salt water or brackish water, raw seafood, or raw seafood juices," the CDC's website adds.
What are the signs of Vibrio vulnificus infection?
According to the CDC, symptoms may differ depending on the type of infection but can include diarrhea, which is often accompanied by cramps, nausea, vomiting and fever.
For bloodstream infections, signs include:
- Low blood pressure
- Blistering skin lesions
For wound infections, which may spread to the rest of the body, the CDC says signs include:
- Discharge or leaking fluids
An infection is diagnosed when Vibrio bacteria is found in the wound, blood or stool of a person, the CDC says, and is treated with antibiotics.
"Doctors may need to amputate a patient's legs or arms to remove dead or infected tissue," the organization's website notes.
