Dermatophytic infections are usually spread through direct contact with an infected person or animal. Clothing, bedding and towels can also become contaminated and spread the infection. Symptoms typically appear between 4 and 14 days following exposure.
Dermatophytic infections can affect the skin on almost any area of the body, such as the scalp, legs, arms, feet groin, and nails. These infections are usually itchy. Redness, scaling, cracking of the skin, or a ring-shaped rash may occur. If the infection involves the scalp or beard, hair may fall out. Infected nails become discolored, thick, and may possibly crumble. More serious infections may lead to an abscess or cellulitis.
