The United States is facing an alarming outbreak of Vibrio vulnificus, a bacteria popularly known as “flesh-eating” and has already caused at least 8 deaths and 32 infections in several Gulf Coast states, according to official public health reports.
The infection, which can cause severe necrosis, amputations, and death within 48 hours, has been detected in Louisiana, Florida, Alabama, Mississippi, and North Carolina and is linked to exposure to warm, brackish water or the consumption of raw or undercooked shellfish.
Unusual increase in cases in 2025
So far this year:
- Louisiana has reported 17 cases and 4 deaths, more than double its annual average.
- Florida register 13 infections and 4 deaths.
- Texas, although with only 5 cases confirmed, remains on alert due to his previous history.
Health authorities explain that rising temperatures and the effects of climate change could be facilitating the proliferation of the bacteria in areas where it was previously less common.
“The bacteria Vibrio vulnificus “It can destroy tissue in a matter of hours. Mortality is high, especially in people with exposed wounds or weakened immune systems,” a CDC spokesperson explained.
What is the Vibrio vulnificus?
It is a bacterium present in warm salt waters, which can infect humans through:
- Open wounds that come into contact with contaminated water.
- Consumption of raw or undercooked seafood, especially oysters.
Once inside the body, it can cause necrotizing fasciitis, a serious infection that destroys soft tissue and, if not treated promptly, requires amputation or it turns out lethal.
How to prevent contagion?
Health authorities recommend:
- Avoid contact with salt water if you have cuts, burns, or wounds.
- Do not consume raw shellfish, especially in coastal areas with active outbreaks.
- Seek urgent medical attention if symptoms such as fever, vomiting, swelling, or redness occur in areas of skin exposed to water.
