Heads Up: Swimmers Itch Is Appearing In Iowa Lakes (Here’s What To Know)

Swimmer's itch caused by microscopic flatworms in Iowa's lakes is affecting summer swimming plans.

Swimming in Iowa's many beautiful lakes is a summer tradition in the Hawkeye State. Whether you're heading to a majestic destination like one of the Iowa Great Lakes, or taking a dip in a local swimming hole, there's no better way to cool off. But this summer, people are coming away with something other than a wet head of hair - a persistent, annoying itch and rash that can be alarming, because many people don't know the cause. Swimmer's itch in Iowa is becoming a problem for locals and tourists, and it may have an impact on this year's summer swimming season. Here's all you need to know about what might be making you itch this summer - and how you can still cool off during the warmer months without having to worry.

Swimming in lakes, like beautiful Lake MacBride, is a great way to cool off in the summer - but swimmers may come away with an unpleasant surprise.

The culprit is a microscopic flatworm that burrows into the skin, causing an allergic reaction known as swimmer's itch.

These tiny worms are transmitted via an unlikely source - aquatic snails, which make the perfect hosts for the tiny pests.

The parasite usually passes through several stages before maturing in the snails - and then infecting humans who later swim in the water.

The result is an unpleasant, unsightly rash. The good news is, the flatworms can't actually live long-term in humans, so the rash clears up after a few days. Anti-itching creams and antihistamines can help ease the discomfort.

Iowa is hard at work combating this scourge, and it's possible that certain lakes with a high snail population may be closed to swimming so they can be treated. Keep an eye on the latest updates for your destination if you're planning a trip.

If you want to play it safe, the good news is Iowa has many other places to go swimming without the tiny residents that can give you an unpleasant surprise!
