Florida has counted 14 Vibrio vulnificus infections and two deaths so far this year, two of the cases in Lee County and none in Collier, and the state's own numbers run close to an ordinary year even as Louisiana drives the Gulf Coast surge in the headlines

Southwest Florida spent Sunday reading a wire story about a Gulf Coast surge in a bacterium that kills people. The number that applies here is smaller and more specific than that headline suggests.

The Florida Department of Health's surveillance figures, current through August 6, put the state at 14 Vibrio vulnificus infections and two deaths for 2026. Two of those cases are in Lee County, neither of them fatal. Collier County has none.

Florida is not where the surge is

For scale, the same department recorded 33 cases and five deaths across all of 2025, and 82 cases and 19 deaths in 2024. Fourteen cases by early August is not an extraordinary Florida year.

The state where the count is genuinely running hot is Louisiana. The Associated Press reports nine cases and five deaths there this year, against a decade average of seven cases and one death over the same period, attributed to the Louisiana Department of Health. That is a small absolute number carrying an alarming death rate, and it is the basis for the regional framing now attached to every Gulf state including this one.

For a reader in Naples or Fort Myers deciding whether to get in the water this week, the honest answer is that the risk here has not changed this summer.

Who is actually at risk

Vibrio vulnificus lives naturally in warm brackish and salt water. That describes the entire coast from Marco Island to Boca Grande for most of the year, and healthy people swim in it constantly without getting sick.

The department is direct about who is different. People with chronic liver disease, kidney disease or otherwise weakened immune systems are roughly 80 times more likely to develop a bloodstream infection from this organism than healthy people.

There are two ways in, and both are avoidable without giving up the Gulf. One is an open wound exposed to the water. The other is raw or undercooked shellfish, oysters above all.

What the department advises

Keep cuts, scrapes, new tattoos and surgical wounds out of warm salt and brackish water. Wash any wound that does get exposed with soap and clean running water.

Wear gloves when handling raw shellfish. If you are in one of the higher risk groups, cook shellfish thoroughly rather than eating it raw, and discard any clams or mussels whose shells are already open before cooking.

If a wound that has been in coastal water turns red, swollen, warm, painful or discoloured, treat it as a same day medical problem rather than a wait and see one. The infections that kill move fast.

The local number to watch

The most useful line in the department's county table is its own footnote to it, which records that Collier and Lee saw an unusual increase in 2022 because of the impacts of Hurricane Ian.

Storm surge is what drives a Southwest Florida spike in this organism, by pushing warm coastal water inland across everything and everyone in its path. Lee County ran five cases in 2024 and four in 2025, and sits at two so far this year. Collier ran one in 2024 and two in 2025, and sits at zero.

With nothing in the Atlantic today and no watch or warning anywhere on this coast, the ordinary precautions are enough. The figure worth watching is not the wire's regional one. It is what the county counts do after the next storm puts water in the streets.
