Pediculosis corporis

**Definition:** A condition of the skin, caused by an infection with the parasite Pediculus humanus corporis. This condition is characterised by pruritus which may lead to sores or thickened discoloured skin. Transmission is by direct or indirect contact with an infected individual or animal. Confirmation is by identification of Pediculus humanus corporis eggs or Pediculus humanus corporis.

**Long definition:** Infestation by body lice (Pediculus humanus corporis). These are usually to be found along the inner seams of clothing, from which they visit the skin only to feed. Itching is the principal complaint and is the result of sensitization to louse salivary antigens. The body is often covered in excoriations and there may be secondary bacterial infection.
