What is a Kerion infection?

It is one of the complications of ringworm (a fungal skin infection), and it often appears as prominent, soft swellings that vary in size according to the affected area and discharge pus. It causes a rash and yellow scales in the affected area, which leads to noticeable hair loss in the inflamed area.
