Synopsis
Pediculosis corporis (body lice) is an infestation with the organism Pediculus humanus corporis, a 2- to 4-mm, wingless, blood-sucking arthropod whose preferred hosts, as its name implies, are human beings. Body lice are rarely found on the skin, as they live in and lay eggs on clothing and bedding. The infestation is extremely pruritic, especially at night when the lice move to the skin to feed. The bites leave behind macules and papules concentrated in the intertriginous regions.
Body lice are found in all countries and climates and may infest any age group. There is no racial or sex predilection. Pediculosis corporis is associated with poor hygiene, poverty, and being undomiciled.
Mortality related to pediculosis corporis occurs from 3 arthropod-borne diseases that the louse may transmit: typhus (Rickettsia prowazekii), relapsing fever (Borrelia recurrentis), and trench fever (Bartonella quintana). The mainstay of treatment is eradicating the infestation.
