Swimmer's itch, also called cercarial dermatitis, appears as a skin rash caused by an allergic reaction to certain parasites that infect some birds and mammals. These microscopic parasites are released from infected snails into fresh and salt water (such as lakes, ponds, and oceans). While the parasite's preferred host is the specific bird or mammal, if the parasite comes into contact with a swimmer, it burrows into the skin causing an allergic reaction and rash. Swimmer's itch is found throughout the world and is more frequent during summer months.

The cause of atopic dermatitis is still unknown. However, several theories attempt to explain its pathogenesis. One theory suggests an underlying metabolically or biochemically induced skin disorder that’s genetically linked to elevated serum immunoglobulin (Ig) E levels. Another theory suggests defective T-cell function. Exacerbating factors of atopic dermatitis include irritants, infections (commonly caused by Staphylococcus aureus), and some allergens. Although no reliable link exists between atopic dermatitis and exposure to inhalant allergens (such as house dust and animal dander), exposure to food allergens (such as soybeans, fish, or nuts) may coincide with flare-ups of atopic dermatitis.
The 'prognosis' of Cercarial dermatitis usually refers to the likely outcome of Cercarial dermatitis. The prognosis of Cercarial dermatitis may include the duration of Cercarial dermatitis, chances of complications of Cercarial dermatitis, probable outcomes, prospects for recovery, recovery period for Cercarial dermatitis, survival rates, death rates, and other outcome possibilities in the overall prognosis of Cercarial dermatitis. Naturally, such forecast issues are by their nature unpredictable.
One of the best treatments of cercarial dermatitis is to apply a corticosteroid cream on the affected areas. Applying cool compresses can also assist control the outbreak of cercarial dermatitis. Other treatments include bathing in Epson salts or baking soda and soaking in colloidal oatmeal baths.
