The announcement said swimmers itch is common this time of year at Sand Hallow affecting a small percentage of the population. Towel off and use sunblock to help prevent it. Swimmers itch is the body's allergic reaction to a free-swimming microscopic parasite (cercarial) found in shallow water. It is found throughout the world and is more frequent during summer months.
Anyone who swims or wades in infested water may be ask risk. However, the larvae are more likely to be in shallow water by the shoreline. Children are most often infected because they tend to play in shallow water more than adults. Less than 7% of the population is effected by Swimmer's Itch, and of those that are, most build an antibody after one reaction and do not experience symptoms again.
