One thing in common between ringworm, jock itch, athlete’s foot, and nail fungus are that they are all caused by a fungus. The fungus, dermatophyte, is classified as tinea– an umbrella category for all infections on the skin. This type of fungus infection can come from sources such as animals, soil, or someone who has the infection.
Types of tinea are:
- Ringworm: Located on the scalp or skin, notable by redness, flakes, and swollen.
- Jock Itch: Found at the groin or upper thighs characterized by itching, redness, and flaking as well.
- Athlete’s foot: Affects skin on the feet between the toes and at the heel of the foot. Can cause itching, burning, redness, and a stinging sensation.
- Nail Fungus: Affects nails either on the toes or fingers, or both. Characterized by discoloration, brittleness, and thickness of the nail.
Since all infections are caused by the same strain of fungi, they can be contagious to other parts of the body and spread from the body to the nails or vice versa.
