What is Swimmers Itch?

Swimmers itch (also known as cercarial dermatitis), is an allergic reaction to certain parasites that live in the bodies of water where people swim. It is usually characterized by small red bumps that cause itchiness and swelling on the affected persons skin. The rash usually goes away within a week after swimming, but can recur if someone swims in the same area again.

What Causes Swimmers Itch?

Swimmers itch is caused by the presence of certain flatworm parasites (known as schistosomes) found in freshwater bodies such as ponds, lakes, and marshes. These parasites are transmitted through the feces of infected birds, which then enter the water through their droppings, and eventually come into contact with humans.

How can Swimmers Itch be Treated?

Swimmers itch is usually treated with over-the-counter remedies such as hydrocortisone cream and calamine lotion. It is important to keep the affected area clean and dry, and avoid scratching or picking at the rash. Taking an antihistamine such as Benadryl can also help with the itchiness.

Swimmers itch is a surprisingly common condition that affects many people. With the right treatment, it will usually go away within a week. It is important to remember, however, that the best course of action is to avoid freshwater bodies known to carry the parasites associated with swimmers itch.
