An infection is the detrimental colonization of a host organism by a foreign species. The infecting organism seeks to utilize the host's resources in order to multiply at the expense of the host. This pathogen interferes with the normal functioning of the host and can lead to chronic wounds, gangrene, loss of an infected limb or even death.

An infection is generally characterized by inflammation, redness of the general area and/or increased temperature of the surrounding tissue, although this varies from case to case.

Some easily identifiable and common infections include:

- Impetigo
- Cellulitis
- Ecthyma
- Erythrasma
- Folliculitis
- Boils
- Leprosy
- Viral exanthem
- Herpes Type 1
- Herpes zoster
- Human papilloma virus
- Varicella zoster
- Dematophyte infection
- Candida albicans
- Pityrosporum
- Scabies
- Eczema
