In brief: Swimmer's itch
Swimmer's itch is an itchy rash caused by certain parasites that normally live in freshwater snails and sometimes on waterfowl.
On warm, sunny days, these parasites can be released into mainly fresh water or occasionally salt water. During your swim, the parasites might burrow into your skin, where they cause the swimmer's itch rash. But humans aren't suitable hosts for them, so the parasites die.
