Skin infection

A skin infection is an infection of the skin in humans and other animals, that can also affect the associated soft tissues such as loose connective tissue and mucous membranes.[citation needed] They comprise a category of infections termed skin and skin structure infections (SSSIs), or skin and soft tissue infections (SSTIs), and acute bacterial SSSIs (ABSSSIs). They are distinguished from dermatitis (inflammation of the skin), although skin infections can result in skin inflammation.

Bacterial skin infections affected about 155 million people and cellulitis occurred in about 600 million people in 2013. Bacterial skin infections include:

Fungal skin infections, sometimes referred to as dermatomycoses, may present as either a superficial or deep infection of the skin, hair, and/or nails. Mycetoma are a broad group of fungal infections that characteristically originate in the skin and subcutaneous tissues of the foot. If not treated appropriately and in a timely fashion mycetoma infections can extend to deeper tissues like bones and joints causing osteomyelitis. Extensive osteomyelitis can necessitate surgical bone resections and even lower limb amputation. As of 2010, they affect about one billion people globally. Some examples of common fungal skin infections include:

Parasitic infestations of the skin are caused by several phyla of organisms, including Annelida, Arthropoda, Bryozoa, Chordata, Cnidaria, Cyanobacteria, Echinodermata, Nemathelminthes, Platyhelminthes, and Protozoa.

Virus-related cutaneous conditions caused by these obligate intracellular agents derive from both DNA and RNA viruses. Some examples of viral skin infections include:
