Dermatophytosis, commonly known as ringworm, is a fungal infection of the skin, hair, and nails. It is caused by a group of fungi called dermatophytes, which feed on keratin, a protein found in these tissues. Despite the name "ringworm," it is not caused by a worm and does not necessarily appear as a ring.

The infection is contagious and can be spread through direct contact with an infected person or animal, or by touching contaminated objects like clothing, towels, or shower floors. Different types of dermatophytes cause infections in different areas of the body. For example, tinea pedis affects the feet, tinea cruris affects the groin, and tinea capitis affects the scalp.

Symptoms vary depending on the location of the infection. Common signs include itchy, red, scaly patches. On the body, it often presents as a circular rash with raised edges and a clearer center. Nail infections can cause thickening, discoloration, and brittleness of the nails. Scalp infections may lead to hair loss in patches.

Diagnosis is usually made based on the appearance of the rash and a physical examination. In some cases, a skin scraping may be examined under a microscope or sent to a laboratory for fungal culture to confirm the diagnosis.

Treatment typically involves antifungal medications, which can be applied topically as creams, lotions, or powders, or taken orally for more severe or widespread infections. It is important to complete the full course of treatment to prevent recurrence. Good hygiene practices, such as keeping the skin clean and dry and avoiding sharing personal items, can help prevent the spread of dermatophytosis.
