The Horrifying Truth About Swimmer's Itch

Swimmer's itch is a rash caused by parasites called schistosomes, which mistakenly burrow into human skin and die, triggering an allergic reaction. These parasites typically target birds and mammals, not humans. The life cycle involves aquatic snails and cercariae, which sometimes confuse humans for their intended hosts.
