UNDERSTANDING VIBRIO INFECTIONS TO STAY SAFE IN MARINE WATERS
What Is Vibrio?
Vibrio is a group of bacteria naturally found in the bays and coastal waters of Texas. If you’ve been in saltwater, you’ve encountered Vibrio. Vibrio encompasses a number of different species, but when most people hear “Vibrio”, they think about the rare, but traumatic flesh and limb destruction that it can cause, informally referring to it as “flesh eating bacteria.”
How can you be exposed?
Infection occurs when Vibrio enters the body through open wounds, even minor cuts or insect bites. Common activities like swimming, fishing, or handling raw seafood can lead to exposure. Risk of infection is most pronounced when water temperature is at or above about 70°F, although infection can occur year-round. A recent study by researchers at the Harte Research Institute for Gulf of Mexico Studies also found that Vibrio populations temporarily increase sharply during Saharan Dust deposition events.
Symptoms of a Vibrio infection
Symptoms of a Vibrio infection can develop rapidly, including pain, swelling, redness, and fever. In severe cases, loss of limbs or death can occur within 24-48 hours if left untreated.
What to do if you are infected?
If you suspect a Vibrio infection (pain, swelling, fever), seek immediate medical attention. Inform healthcare providers about recent saltwater exposure and potential Vibrio infection.

MINIMIZE VIBRIO RISKS
Avoid Saltwater with Open Wounds: Refrain from swimming or wading if you have cuts or abrasions.
Use Protective Gear: Wear puncture-resistant gloves when handling seafood and closed-toed shoes in water.
Wound Care: Immediately treat any wound that has been exposed to saltwater by flushing and cleaning with warm water and antibacterial cleanser; Chlorhexidine -based products such as Hibiclens® can be purchased at your local pharmacy and provide lasting antibacterial effect. Apply a topical antibacterial ointment and cover the wound with a clean dressing or Band -Aid. Fishermen, bathers, and others should carry, or have immediate access to, small bottles of Hibiclens and antibiotic ointment.
