Skin diseases, such as ringwork, thrush, nail infections and athlete’s foot are caused by fungi.
Common bacterial infections of the skin include folliculitis (insert link), impetigo, erysipelas and cellulitis.
Viral infections are often associated with a particular type of skin rash, for example measles, chicken pox, hand, foot and mouth disease, cold sores and shingles. Patients with eczema have a pre-disposition to getting two types of viral infection; molluscum contagiosum and widespread cold sore infections. Infection with HIV may also be associated with more severe forms of common skin conditions.
Several types of skin infection are caused by a parasite. These infections can spread beyond the skin to the bloodstream and organs.
