The New York Times • • general
Key Points:
- Five residents in Louisiana have died this year from Vibrio vulnificus, a flesh-eating bacteria found in warm seawater and brackish water, with all nine reported cases linked to wounds exposed to seawater.
- Vibrio infections typically occur from May to October when water temperatures rise, but climate change is causing outbreaks in previously cooler regions, such as Long Island Sound.
- The CDC estimates around 80,000 cases of vibriosis occur annually in the U.S., with Vibrio vulnificus infections resulting in a 20% mortality rate and severe symptoms including diarrhea, vomiting, and potentially fatal bloodstream infections.
- Other states like Florida have also reported Vibrio vulnificus cases and deaths this year, with increased risk following severe weather events that push brackish water inland.
- Health officials advise avoiding seawater exposure with open wounds, thoroughly washing wounds after contact, and properly cooking seafood to reduce infection risk.
