The lake covers 15.33 sq km and has a maximum depth of 24 to 25 m. Preventive actions before or after water exposure have been proposed, but no scientific evidence exists on their efficacy.ДЄ prospective survey of swimmerвЂ™s itch among persons with water-based activities was conducted in July 2000 at Douglas Lake, Cheboygan County, Michigan. Intense itching and papules are present 10 to 15 hours later, continuing for about a week. Mild itching and macular eruptions occur 1 to several hours after a person leaves the water.

If instead they penetrate human skin during recreation or work in the water, an inflammatory response occurs. At one point in the cycle, snails release cercariae (free-swimming larval stage of the parasite) into the water, where they may encounter and enter ducks and other birds. The schistosomes for swimmerвЂ™s itch have a 2-host life cycle, an avian definitive host and a snail intermediate host. 29, 30 We conducted a prospective study at a Michigan lake to obtain an incidence rate and identify risk factors for swimmerвЂ™s itch. 2вЂ“ 14 The literature on humans and swimmerвЂ™s itch consists largely of clinical and outbreak reports. Since discovery of the parasites responsible for swimmerвЂ™s itch, 1 most research has focused on the schistosomesвЂ™ life cycle and biological control methods. It causes intense discomfort, discourages recreational water use, and leads to economic loss for lake regions if people decide to vacation elsewhere.

Cercarial dermatitis, or swimmerвЂ™s itch, is a skin condition that affects people engaged in open-water activities in fresh and salt-water areas around the world.
