Ring Worm (Tinea)
by MedPlus Team, May 19, 2017
Ringworm is a fungal infection of the skin, also known as dermatophytosis, affecting different areas of the body. It is generally classified depending on the area of the body affected and is caused by related yet different species of fungi. The name comes from the type of rash it produces which is typically scaly, itchy with an elevated ring-like border.
It generally occurs in the moist areas of skin and can come from the spores in the soil or from close contact with someone with the condition. It tends to be very contagious and spreads easily by contaminated objects, contact with other people, between different parts of one’s own body, or infected pets or farm animals.
It starts as a red, scaly patch or bumps. It tends to be very itchy and uncomfortable, but it’s not painful or dangerous. Hair loss may occur in the area affected, especially when it affects the scalp. Ringworm should be considered if you notice:
i) Ring-like patches that have a red, raised border and normal skin in the center
ii) Itchy, red, raised, scaly patches

iv) Hair loss with a scaly rash
