The more time you spend in infested water, the higher your risk of swimmer's itch. Children may have the highest risk, since they tend to play in shallow water and are less likely to dry off with a towel.
Some people are more sensitive to swimmer's itch than others are. And, your sensitivity can increase each time you're exposed to the parasites that cause swimmer's itch.
