What is Swimmer's Itch?
Swimmer's itch is a skin reaction to contact with the larvae of a parasitic fluke, which are found in contaminated freshwater. The larvae are called cercariae. They are almost invisible to the naked eye because of their size. If you swim in contaminated water, the cercariae may stick to your skin. When you get out of the water and your skin dries, the cercariae bite as they penetrate your skin. They die shortly after.How do people get Swimmer's Itch?
The cercariae that are found in freshwater come from infected waterfowl. The cycle begins when snails become infected by contaminated waterfowl feces. The cercariae are released from snails to swim in fresh water where they again infect waterfowl - or swimmers; cercariae can't tell the difference. Thus, humans are considered accidental hosts.
