Schistosome dermatitis, or "swimmers itch” occurs when skin is penetrated by a free-swimming, fork-tailed infective cercaria.
Upon release from an the snail host, the infective cercariae swim, penetrate the skin of the human host, and shed their forked tail, becoming schistosomulae. The schistosomulae migrate through several tissues and stages to their residence in the veins.
