Swimmer's itch or schistosome cercarial dermatitis is a skin reaction that certain people have to the entry of a larval stage of certain flatworms into the epidermal layer of the skin.

After the parasite enters, it dies and may cause dermatitis in individuals who have been previously sensitized. This sensitivity will rarely disappear; it usually get worse to subsequent exposures.
