As temperatures warm up in Michigan, residents might be tempted to take a dip in a lake, but there’s a chance you could end up itching later.
Swimmer’s itch is a skin rash caused by an allergic reaction to microscopic snail parasites that then complete their life cycle in some birds and mammals, according to the Centers for Disease Control and Prevention. People can pick up the parasites if they come in contact with contaminated water — by swimming or spending time in a contaminated freshwater or saltwater lake or public pool.
Luckily, most swimmer’s itch cases don’t require medical attention, according to the CDC, and can be treated with corticosteroid creams and cold compresses, among other things.
Here’s what to know about swimmer’s itch and how to avoid it in Michigan waters if you’re considering a swim as summer approaches.

Swimmer’s itch is a skin rash caused by an allergic reaction to microscopic parasites that infect some birds and mammals, according to the Centers for Disease Control and Prevention.

Swimmer’s itch is found throughout the world and is more frequent during summer months.
Swimmer’s itch is often incorrectly attributed to E. coli exposure, according to the Clean Lakes Alliance.
