Swimmer's itch was known to exist as early as the 19th century, but it was not until 1928 that a biologist found that the dermatitis was caused by the larval stage of a group of flatworm parasites in the family Schistosomatidae. [7] The genera most commonly associated with swimmer's itch in humans are Trichobilharzia [4] and Gigantobilharzia.
Symptoms of all forms of schistosomiasis are caused by the immune system's reaction to the eggs, rather than the adult worms themselves. [5] A few hours to days after cercariae invade the skin, some people experience pruritus and raised papules at the site of penetration. This is called cercarial dermatitis, also known as swimmer's itch.
