Tinea is a fungal infection that affects the skin, hair, or nails. It is commonly known as ringworm due to the circular, red, and itchy rash it often produces. Tinea can occur in various forms, such as tinea corporis (body), tinea pedis (athlete's foot), and tinea capitis (scalp). The infection is contagious and can spread through direct contact or contaminated surfaces. Treatment for tinea typically involves antifungal medications, which can be topical or oral, depending on the severity. Maintaining good hygiene and keeping the affected areas dry can help prevent the spread and recurrence of the infection. It's important to consult a healthcare professional for proper diagnosis and treatment.
