5 dead, 4 hospitalized from flesh-eating bacteria outbreak, health officials say....

Louisiana health officials are reporting at least five deaths from Vibrio vulnificus in 2026, a potentially deadly bacterium found in warm coastal and brackish waters. Nine infections have been reported so far this year, and all nine were associated with wounds exposed to seawater.
A few important points:
“Flesh-eating bacteria” is a media shorthand. Vibrio vulnificus can cause necrotizing infections that destroy skin and soft tissue, but not every infection is a “flesh-eating” infection.
The bacteria can enter through cuts, scrapes, or other open wounds exposed to warm seawater.
Eating raw or undercooked shellfish, particularly oysters, is another route of infection.
Severe illness can progress extremely quickly. Louisiana health guidance notes that roughly one in five people with reported V. vulnificus infection die, although the risk is much higher in certain vulnerable groups.
People with liver disease, diabetes, or weakened immune systems are at particularly high risk of severe disease.
Practical takeaway: If you have an open wound, avoid warm saltwater or brackish water. And cook shellfish thoroughly rather than eating it raw.
This is a current 2026 Louisiana report, not a claim that the bacteria is spreading person-to-person; Louisiana guidance says there is no evidence of person-to-person transmission.
Yes — this headline refers to Louisiana, where health officials have reported a sharp rise in infections from Vibrio vulnificus, often sensationally called a “flesh-eating” bacterium.

9 people have been infected in Louisiana in 2026, and 5 have died. All nine cases were hospitalized, according to the Louisiana Department of Health.
All nine cases involved wounds exposed to seawater, making beach and coastal-water exposure a particular concern.
The bacteria thrives in warm coastal or brackish water and can enter the body through cuts or open wounds. In severe cases, it can cause necrotizing infections and bloodstream infections.
Louisiana typically sees around seven cases and one death during a comparable period over the previous decade, so five deaths is unusually high.
For beachgoers: don't enter seawater with an open wound, keep cuts completely covered if exposure is unavoidable, and wash wounds promptly with soap and clean water afterward. People who develop rapidly worsening pain, redness, swelling, blistering, fever, or other concerning symptoms after seawater exposure should seek medical care urgently.
Importantly, this does not mean beaches are generally unsafe or that the bacterium spreads from person to person. The principal concern in these Louisiana cases has been wound exposure to seawater.
