This is an allergic dermatitis. It is prominent in Europe and N. America. The itch comes because the organisms crawl under our skin and die, causing the hypersensitivity reaction. The snails that allow this organism to mature can be killed with copper salts. This happened in Little Washoe Lake in 1994 or 1995 or 1996 when the water levels were so low.
Treatment is supportive and symptomatic.
