Pediculosis is infestation by lice. On the human body 3 types can parasitize, which differ in habitat and structure: head, wardrobe and pubic.
A head louse lives in the scalp, mainly on the temples, the back of the head and crown. The clothes one is parasitic on the human body, mainly in the folds and seams of linen and clothing. The pubic one lives in the hairy part near the genitals, but with massive invasion and in other places, up to the eyebrows. Head and body lice are carriers of typhus and recurrent typhus. A mature female lays between 3 and 10 eggs per day. Eggs have a chitinous shell and are called nits. Adult individual lives 9-10 days.
They spread through contact with people in groups (kindergartens, camps, boarding schools, schools, etc.), in crowded public transport, when sharing clothes, bedding, hairbrushes, brushes, etc. They rapidly spread in children’s groups through hats, bedding, and combs. Infection of children with pubic lice occurs from adults, as well as through clothing.
It has been established that with an increase in the temperature of the human body, it begin to crawl intensively towards other people. The widespread infestation contributes to the crowding of people, the lack of conditions for personal hygiene.
The leading clinical symptom is severe itching of the skin. As a result, scratching occurs with the addition of a secondary bacterial infection, abscesses and an increase in the posterior cervical lymph nodes. There may be roughness and discoloration of the skin from bites due to hemorrhages. Stitched children become irritable, sleep poorly, their interest in learning decreases.
When the body lice on the ground bite red spots appear with a diameter of 2-4 mm, which may later lead to the development of pustules.
Pedic pediculosis in children is more common only after puberty. Pubic louse lives outside of the human body for 10-12 hours.
The main diagnosis is the detection of mature individuals or nits. Nits look like white balls at the base of the hair, which cannot be removed, as they are attached to the hair with a secret of the female. Parasites are usually found when combing hair with a frequent comb, when examining the temporal-occipital part of the head, folds of underwear, and seams of clothing, belts, and a collar. Pubic ones look like small brown formations at the base of the hair.
It includes adherence to personal hygiene, regular washing in the bath or bath, frequent change of linen, the individual use of hats and hairbrushes.
