Health officials in Florida are warning people about a dangerous bacteria called Vibrio vulnificus, often known as a “flesh-eating bacteria.” So far in 2025, it has killed four people and infected a total of 11, according to Florida’s health department.
What is Vibrio vulnificus?
This bacteria is usually found in warm, coastal waters and can enter the body in two ways:
- Through open wounds when swimming
- By eating raw or undercooked seafood, especially oysters
What Are the Symptoms?
People infected with Vibrio vulnificus may experience:
- Stomach issues like vomiting, diarrhea, and pain
- Skin problems such as redness, swelling, fever, and dark-colored skin
- In serious cases, the bacteria can cause skin infections so severe that the skin and tissue start to die — this is why it’s called a “flesh-eating” bacteria
If the infection reaches the bloodstream, it can lead to life-threatening problems like:
- Septic shock (a dangerous drop in blood pressure)
- Painful blisters on the skin
- And in nearly 50% of such severe cases, it can be fatal
Who Is at Greater Risk?
Healthy people usually recover quickly, but those with weak immune systems or liver problems are more likely to get very sick. The CDC says people with conditions like diabetes, cancer, liver disease, HIV, or those taking immune-suppressing medications should be especially careful.
How Is It Treated?
Doctors can diagnose the infection by testing stool, blood, or wound samples.
- For mild cases: Drink lots of fluids to stay hydrated.
- For severe cases: Surgery may be needed to remove infected tissue, and in extreme situations, doctors may have to amputate a limb to save a patient’s life.
How to Stay Safe
Health experts advise people to:
- Avoid swimming in warm waters if you have cuts or wounds
- Do not eat raw oysters or shellfish
- Use gloves when handling raw seafood
- Keep raw seafood separate from other foods to avoid spreading bacteria
Previous Cases
In 2024, Florida reported 82 infections and 19 deaths. In 2023, there were 46 cases and 11 deaths. So far in 2025, 11 people have been infected and 4 have died.
There is no sign that the infection spreads from one person to another, but taking precautions is very important.
