What is swimmer’s itch?
Swimmer's itch (cercarial dermatitis) is an irritating rash that can develop after swimming or wading outdoors. It’s most common in freshwater lakes and ponds, but can occur in saltwater. The condition is a rash brought on by the body's allergic reaction to the larvae of certain microscopic parasites. When swimming or wading in areas where these parasites live, they can latch on and burrow into the skin.
The condition is uncomfortable, but it usually clears up on its own after a few days to a week. It is important not to scratch, which can break the skin and lead to infection. In the meantime, you can control the itch with over-the-counter remedies or prescription medication. Your MinuteClinic® provider can assess the symptoms and recommend a treatment plan to calm the irritation. Swimmer's itch is not contagious.
What symptoms can occur with swimmer's itch?
Symptoms of swimmer's itch include burning, tingling and itching of the infected skin. The rash associated with swimmer's itch typically show up as small reddish pimples within 12 hours of exposure and may turn into small blisters. The condition usually affects only the exposed skin that is not covered by swimsuits, waders or wetsuits. Typically, swimmer's itch symptoms worsen with each subsequent exposure to the parasite.

Swimmer’s itch treatment causes, symptoms and treatment
The parasites responsible for swimmer's itch live in the blood of waterfowl and mammals that are near lakes and ponds including ducks, geese, gulls, beavers and muskrats. The parasite's eggs enter the water when the host animals defecate. Before infecting birds, animals or people, the hatched parasites live for a time inside certain species of snail to evolve into the next stage of their lifecycle, cercariae, then release into the water.
The host snails live near the shoreline, which is why infections most often occur there. Although humans are not suitable hosts, the larvae may burrow into a swimmer's skin and cause an allergic reaction. They cannot develop inside a human, so they soon die.
Typically, the condition clears up on its own. In the meantime, you can relieve the itching with over-the-counter products. If the itching is severe, prescription medication may be necessary.
- Apply waterproof sunscreen before going in the water: It’s been reported to protect the skin from the parasite that causes swimmer's itch
- Avoid shallows near the shoreline: Swim in deeper water if you're a strong swimmer. Avoid marsh areas where the snails live.
- Choose swimming spots with care: Avoid places where swimmer's itch is a known problem, and check warning signs for possible contamination.
- Do not feed birds: The birds that are near swimming areas or on docks.
- Rinse after the swim: Wash exposed skin with clean water right away. Dry the skin thoroughly and vigorously with a towel. Launder swimsuits after each time. Reapply sunscreen if staying in the sun.
