The pediculosis (pediculosis) is an illness which is widespread worldwide. Louses parasitize on a human body, eating its blood. There are several kinds of louses. They live on pilar part of the head of the person, can live on linen and articles of clothing, and also to live in area of a pubis. In rare instances louses also meet on other parts of a body where hair – on a beard, eyebrows grow. As experience of specialists testifies, on a body of the person rather limited quantity of louses depending on amount of its blood can live. The main nutrients for louses is blood and a lymph. Louses bite through skin and inject saliva into the formed wound. Saliva of louses can contain different microbes activators of dangerous infectious illnesses. So, fever, typhus and other diseases in such a way can be transmitted. After stings of louses of people feels a severe itch, combs skin on site of stings. Louses move, creeping.

The pediculosis is transferred by direct contact with the infected person or after use of sanitary products of the patient. Also louses can creep from one head on another in places where people stay in rather close contact: in public transport, in the pool, on the beach. In spite of the fact that there is an opinion on a pediculosis as about a social illness which is very closely connected with hygiene till today the reason of a wide circulation of louses among clean people remains not investigated. So, scientists established that louses more willingly "lodge" on the head with clean hair.

In ten-fifteen days the adult louse capable to fully lay eggs grows from a larva. The louse can live till 38 days. Nits of head louses are white balls which louses attach at the basis of hair. As a rule, identification of nits demonstrates existence at a sick pediculosis. Eggs of a louse attach so that during washing of the head they cannot be removed.
