"Swimmers' itch" (cercarial dermatitis).
Cercarial dermatitis is a parasitic disease affecting the skin. It may be encountered in fresh or salt water and is global in its distribution. It is a potential economic hazard to persons who work in aquatic environments and to the tourist industry. Cercarial dermatitis should be considered a potential risk whenever warm-blooded and molluscan hosts share a water resource with man. It is characteristically a self-limited, severely itching rash that lasts about one week and may be easily mistaken for insect bites. Prevention of the disease is difficult. Treatment is primarily directed toward relief of symptoms and prevention of infection.
