Threlkeld said people susceptible to Vibrio infections are more likely to be people exposing open cuts in water or those with suppressed immune systems.

“It is, in fact, quite rare in normal individuals, so don’t let it impact your vacation,” Threlkeld said.
If you're seeing any blisters, or redness after a trip to the ocean, doctors urge you to get it checked out - just in case.
