Causes And Risk Factors Of Swimmer's Itch

Increased Sensitivity

Some individuals have an increased sensitivity to the parasite that causes swimmer's itch. Individuals with repeated exposure to bodies of contaminated water have an increased sensitivity to the parasite and the allergic reaction that develops as a result. Individuals with an increased sensitivity to the parasite typically begin to see symptoms as soon as one hour after exposure to the parasite. These patients are typically also at an increased risk for developing more serious symptoms and needing medical intervention. As such, individuals who have contracted swimmer's itch in the past should avoid or limit swimming in water that may be contaminated with the parasite.
