WHO:

[11:37 a.m. ET] - USA Today - Louisiana Department of Health reported five fatalities linked to flesh-eating bacteria infections.

[11:37 a.m. ET] - USA Today - Nine patients infected with Vibrio vulnificus had underlying health conditions.

WHAT:

[11:37 a.m. ET] - USA Today - Florida has reported 14 Vibrio vulnificus cases and two deaths so far in 2026, compared to 33 cases and five deaths for all of last year.

[11:37 a.m. ET] - AP - Louisiana health officials confirmed that the Gulf is an ideal environment for Vibrio bacteria due to the right amounts of salt and heat, which allows the organism to proliferate.

[11:37 a.m. ET] - USA Today - Five people have died from infections caused by Vibrio vulnificus in Louisiana in 2026.

[11:37 a.m. ET] - USA Today - A total of nine cases of Vibrio vulnificus bacteria have been reported in Louisiana in 2026.

[11:37 a.m. ET] - USA Today - The annual average of cases in Louisiana over the previous 10 years was seven cases and one death.

WHERE:

[11:37 a.m. ET] - USA Today - The infections occurred in Louisiana, specifically in coastal waters.

WHY:

[11:37 a.m. ET] - AP - A 2023 study found that the northernmost case of Vibrio vulnificus has been shifting by about 30 miles each year, indicating a potential impact of climate change on the spread of the bacteria.

[11:37 a.m. ET] - USA Today - The presence of Vibrio vulnificus increases as coastal waters get warmer, leading to higher cases in Louisiana compared to past years.

[11:37 a.m. ET] - USA Today - Infections can occur when open wounds are exposed to salt water or brackish water.

HOW:

[11:37 a.m. ET] - USA Today - Infections can occur from exposure to seawater or by consuming raw or undercooked seafood, particularly oysters.

Florida has reported 14 cases of Vibrio vulnificus and two deaths so far this year, a notable decrease compared to 33 cases and five deaths for all of last year. Health officials in Louisiana have confirmed that the Gulf provides the perfect conditions for Vibrio bacteria to thrive, thanks to the right levels of salt and heat. A study from 2023 revealed that the northernmost case of Vibrio vulnificus has been moving about 30 miles each year, suggesting that climate change may be influencing the spread of this bacteria.

In Louisiana, five fatalities have been reported due to infections caused by the flesh-eating bacteria Vibrio vulnificus, with a total of nine cases identified this year. The Louisiana Department of Health noted that all nine patients had underlying health conditions, and infections typically occur when open wounds are exposed to warmer coastal waters or through the consumption of raw seafood, especially oysters. Symptoms can appear within 24 hours after exposure, including fever, chills, and skin issues, highlighting the increasing risks as coastal waters warm.
