For most families, summer vacation means taking a trip to the cottage for barbecues and fun activities out on the beach. If your kids are spending more time swimming in a lake this summer, they may develop a minor skin infection or rash, more commonly known as “swimmer’s itch”. This condition is caused by small larvae found in certain lakes and bodies of slow moving fresh water that typically live on snails during their life cycle. These larvae are so small that they are not visible to the naked eye. When kids are out swimming or wading, these larvae can stick to the skin and cause an allergic reaction. Although generally harmless, swimmer’s itch can be unpleasant and last for a few days.
