This is a fungal infection caused by a fungus in the genus Trichophyton, it causes scaling, flaking, and itching of the affected skin usually in moist areas between the toes but may spread to underarms and groin. It has very low incidence in bare foot cultures (presumably as bare feet are generally dry and well ventilated). Transmission occurs when people go barefoot in a moist communal environment, such as a changing room or shower, and then put on shoes.
Treatment is usually straight forward and the fungus responds well to over-the- counter treatments available from chemists. These anti fungal agents can take the form of a spray, powder, cream, or gel and contain active agents such as miconazole nitrate, clotrimazole and tolnaftate.
If you have athletes foot try to avoid wearing shoes around the house to allow your feet to dry out and let your shoes to dry out before wearing. Also try to avoid spreading the infection to other parts of the body by washing hands after touching feet.
