Causes And Risk Factors Of Swimmer's Itch

Swimmer's itch, also known as cercarial dermatitis, is an allergic reaction to parasites that contaminate both fresh and salt water through infected snails. Individuals who swim in lakes, streams, ponds, and oceans may come into contact with the parasite, which buries itself into the skin of the swimmer. As the parasite feeds on the skin of the swimmer, an allergic reaction occurs in the form of a rash, along with burning, itching, and the formation of small blisters. Symptoms usually onset fairly quickly and can happen within minutes of contact with infested water.
