Tips to prevent swimmer's itch.

IRON MOUNTAIN -- Warm weather means more people are finally starting to hit the beach.  And though you always need to take care while in the water, you also might need to watch out for something you can't see.

Swimmer's itch is a parasite that is carried by snails and water fowl that burrows under the skin causing an uncomfortable rash.  Most cases of swimmer's itch don't require medical attention and can be treated with something as simple as an anti-itch lotion.  Officials do caution, however, not to itch the rash, as it may cause the rash to become infected.

Swimmer's itch usually lasts about a week and is common throughout natural lakes in Michigan, but there are things you can do to keep the bug at bay.

"Prevention--after you get out of the water, vigorously rub your skin to remove the parasite that you might have gotten onto your skin," said health sanitarian Sheila McNaulty.  She also recommends showering as soon as possible after your swim.

Lakes that have marshy areas or an abundance of birds often carry swimmer's itch.  It's also commonly found closer to shore, which means parents should keep their eye out.

"Children can be more susceptible because, of course, when children are swimming, they tend to hang out in the shallower water, and this is where also more swimmer's itch is located," McNaulty said.

A few cases have already been reported in the Dickinson County area, though cooler weather has kept people off beaches later than normal.

If you think you have swimmer's itch or have any questions, you're encouraged to contact your local health department.
