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.
