Pediculosis caused by Pediculus capitis, the human head louse, is the most prevalent parasitic infestation of humans worldwide, especially among school children of 3-12 years old (7). More Uian 6-12 million people in the United States (US) are estimated to have pediculosis. Synq>toms of infestations are relatively mild, but the social, mental and economic consequences are substantial. Pediculosis is not widely tolerated in the US and is repeatedly treated by a variety of over-the-counter pediculicides, which are exclusively limited to those containing pyrethrin or permetfarin as active ingredients. Because these pediculicides share a common mechanism of action on the voltage-sensitive sodium channel in the nervous system of insects (2), dieir repetitive and continued use has imposed a high pressure for the selection of resistant louse populations. 

The two species that belong to this group include Pediculus humanus capitis (head louse) and P. humanus corporis (body louse). The eggs (or nits) remain firmly attached to the hair, and in about 10 days the lice hatch to form nymphs, which mature in 2 weeks. The lice become attached to the base of the hair follicle and feed on the blood of the host.10 Pubic or crab lice are found on the hairs around the genitals, but may occur... 

Phthiriasis palpebrarum is an imcommon eyelid infestation by Phthiruspubis (crab louse) and, less commonly, by the Pediculus bumanus species, P. humanus var. capitis (head louse) and P humanus var. corporis (body louse). The term pediculosis refers to infestation by the two P humanus species and should not generally be used when referring to eyelid manifestations. 

Three species of lice occur as parasites on humans. These lice are blood suckers, and they can be disconcertingly abundant under unsanitary conditions. The human louse, Pediculus humanus, occurs as two races, which feed on different parts of the body. The head louse, capitis race, occurs in the hairs of the head, to which it attaches its whitish eggs, also known as nits. The body louse corporis race, also known as the cootie, feeds on the human body, and hides and lays its...

It is not certain when people first started wearing elothes. Scientists estimate that this happened more than 100,000 years ago, beeause the body louse (pediculus humanus humanus) apparently diverged from the head louse (pedi-culus humanus capitis) at that time. The first elothes were made from natural materials animal skin and furs, grasses and leaves and the first needles are recorded about 30,000 years ago.
