Athlete's foot, also known as tinea pedis, is a common fungal infection of the skin on the feet and toes. It can spread to other areas of the body, including the groin (tinea cruris) and the hands (tinea manuum). Other areas of the body where athlete's foot can spread include the scalp, face, chest, and nails.
On the feet, athlete's foot typically appears as a scaly, red, itchy rash between the toes. It can also cause blisters and cracked and peeling skin. When athlete's foot spreads to other parts of the body, it can look different. For example, it may appear as a red, itchy rash on the groin (tinea cruris) or a dry, scaly rash on the hands (tinea manuum).
Athlete's foot can also spread to the scalp, face, and chest. On the scalp, it can cause red, scaly patches and hair loss. On the face, athlete's foot can cause red, itchy patches and on the chest, it can cause a red, scaly rash.
Finally, athlete's foot can also spread to the nails. This can cause the nails to become thick, yellow, and brittle.
It is important to note that athlete's foot is contagious and can be spread through direct contact with an infected person or through contact with contaminated surfaces. Therefore, it is important to practice good hygiene and to wash your hands and feet regularly to help prevent the spread of the infection.
