*Do not enter bodies of water if you have cuts or abrasions; if injured, clean wound at once to reduce risk of infection.*
Many harmful organisms are found in lakes, rivers, along the coast, and in other bodies of water. Some bacteria may lead to destructive soft-tissue infections and other illnesses, the Alabama Department of Public Health (ADPH) cautions.
Most soft-tissue infections occur with either injury or with conditions such as poorly controlled diabetes or low immunity. However, sometimes otherwise healthy people can develop a skin infection after skin injury and being exposed to natural bodies of water. Some bacteria can cause more severe infections than others.
In brackish and warm sea water such as bay or gulf waters, Vibrio bacteria occur naturally. These bacteria can cause disease in people who eat contaminated seafood and in those with open wounds that are exposed to seawater. While there are numerous infections every year, a small number of people develop serious or sometimes fatal infections.
If a person has open wounds, cuts, abrasions, and sores, stay out of the water. Persons with low-immune systems, cancer, diabetes, liver disease, and other chronic conditions should avoid eating raw or undercooked seafood, especially oysters.
Vibrio bacteria can enter the body through a break in the skin or by consuming contaminated seafood. If a person gets a cut while in the water, immediately wash the wound with soap and fresh water. If the wound shows any signs of infection (redness, pain, or swelling) or if the cut is deep, get medical attention immediately.
Vibrio illness symptoms may include diarrhea, vomiting, abdominal pain, chills, fever, shock, skin lesions, and wound infections. In someone with a compromised immune system, the bacteria can infect the bloodstream and may result in death. With Vibrio skin infections, surgery may be necessary. For all cases of Vibrio, it is important to begin treatment immediately because early medical care and antibiotics improve survival.
The Centers for Disease Control and Prevention estimates each year in the United States 80,000 people become sick with vibriosis, and 100 people die from their infection. As of June 15, there have been four cases of vibriosis reviewed and verified in Alabama and six other vibriosis investigations are either open or awaiting review.
