10 Essential Oils For Swimmer's Itch (Cercarial Dermatitis) + Other Home Remedies

Swimmer’s itch, also called cercarial dermatitis, is a skin rash which is caused by an allergic reaction to the larvae of small worm-like parasites called schistosomes.

Schistosomes spend their life cycle as parasites in the bloodstream of aquatic mammals, ducks, or other waterfowl and in the bodies of water snails.

While the parasite’s preferred host is the specific mammal or bird, if the parasite comes into contact with a swimmer, it may burrow into the skin causing a rash and an allergic reaction.

Note – it can’t enter the deeper tissues or bloodstream.

Swimmer’s itch usually occurs during the summer months. It cannot be spread from one person to another and is not contagious. It is less common in salt water (called clam digger’s itch).

Symptoms

Symptoms may include:

  • a rash may appear within 12 hours after infection;
  • a burning or itching feeling on the skin;
  • a rash which typically goes away in about seven days;
  • the rash only occurs on areas exposed to the lake water.

Notes – try not to scratch since scratching may cause the rash to become infected. The severity of the symptoms depends on how many larvae get on to the skin.

When to Call the Doctor

You should contact your healthcare professional when:

  • the rash lasts over 14 days;
  • itching becomes severe;
  • the rash becomes infected.

Causes

Swimmer’s itch is caused by a parasite found in many lakes. Also, similarly to the reaction to poison oak or poison ivy, cercarial dermatitis is a reaction of the skin to an irritant.

Your healthcare professional may ask you questions to help make a diagnosis, such as:

  • medical history, especially if you have any allergies and take any supplements or medications;
  • if other people who were in the water with you also got a rash;
  • if you have been wading or swimming recently in a fresh water;
  • when did the rash start?

Treatment

Common treatments include:

  • treatment includes corticosteroid creams or Calamine lotions.
