The most common infestation in humans is by the head louse. These parasites feed on human blood by piercing the skin. The injected saliva contains many irritant chemicals that cause itching. This parasite is acquired easily by close physical contact, by sharing personal products (such as hats, brushes, combs and garments) and by sharing the same bedding. Lice are classified as ectoparasites because they have the capacity to feed and live off their human hosts. The head louse (Pediculus humanus capitis) and the body louse, known as (Pediculus humanus corporis) are of similar size and structure, and can be crossbred. The third type is the pubic louse (Pthirus pubis), often referred to as a “crab,” which is morphologically different from the other two species. Pubic lice have an affinity for the groin and genitals, can infest almost any hair-growing area, including beards and eyelashes.
