The areas of skin affected by seabather’s eruption is generally under the garments worn by bathers and swimmers where the organisms are trapped after the person leaves the water. These schistosomes all use different snail intermediate hosts, commonly those from the families Nassariidae, Lymnaeidae, and Physidae.Ĭercarial dermatitis should not be confused with seabather’s eruption, which is caused by the larval stage of cnidarians (e.g., jellyfish).

Systemic antihistamines or topical antihistamines or corticosteroids can be used to reduce symptoms. Treatment of cercarial dermatitis has not been evaluated in clinical trials. Skin penetration by these zoonotic cercariae causes dermatitis, but the cercariae do not mature into adults in the human body. Minimal symptomatic treatment and good hygiene to prevent itching and secondary infections are usually sufficient treatment for most cases of cercarial dermatitis. These cercariae seem to have a chemotrophic reaction to secretions from the skin and are not as host-specific as other types of human-infecting schistosomes.
