SWIMMER'S ITCH 

Visiting the lake is a great way to cool off during the summer. However, even on premiere lakes like Big Green, it can come with some risk: Lakes, pools, and all bodies of water can be home to bacteria and parasites that can cause illnesses.

 

Organisms that cause this skin reaction are most commonly noticed in early summer and typically persist in the water for 4-6 weeks. Swimmer's itch is caused by an allergic reaction to a parasite that usually infects birds, snails, and other aquatic animals. It is not dangerous to humans and it is not contagious, but it can cause itching that is uncomfortable. Symptoms usually resolve within one week.

 

There are no effective ways to eliminate swimmer's itch within the water or on a beach.
