Flesh-eating bacteria has killed 5 in Louisiana this year, officials say

TL;DR

Flesh-eating bacteria Vibrio vulnificus has caused at least five deaths and nine hospitalizations in Louisiana in 2026.
All patients contracted the bacteria through wounds exposed to seawater and had underlying health conditions.
This year's cases in Louisiana are significantly higher than the 10-year average of seven cases and one fatality per year.
Florida has also reported two deaths from Vibrio vulnificus this year and experienced higher infection rates after major storms.
Experts suggest rising water temperatures due to climate change are contributing to the risk and spread of Vibrio vulnificus, with the bacteria detected in New York's Long Island.
Vibrio vulnificus is the most serious species of Vibrio bacteria, with about one in five infected individuals dying from it.
Infections are common between May and October when ocean water is warmest, contracted through open wounds in seawater or consumption of raw/undercooked shellfish.
Symptoms can include fever, skin discoloration, drainage, pain, swelling, chills, low blood pressure, and gastrointestinal issues.
To avoid infection, people are advised to stay out of salt or brackish water, wash wounds after exposure, and thoroughly cook seafood.
