What is pediculosis

Pediculosis (lice) is a parasitic disease of the skin and hair. According to the latest data, over the past 10 years in Russia, this disease has recovered from 220 to 300 people per 100 thousand of the population. In the capital in 2002, 791 cases were recorded for every 100 thousand people, children under 14 years old accounted for 15% of the cases. The most interesting thing is that the carriers of this disease are most often adults.

Allocate one of the reasons for the spread and development of pediculosis – a lot of refugees from the countries of the former USSR and, of course, homeless people. Lice are small wingless insects, the food of which is human blood. The form of lice is flat, elongated-rhombic, on the legs, with a small mobile proboscis, due to which the insect is attached to something. Lice that have not yet drunk blood have a grayish-brown color, the same ones that have drunk blood-red or black. To feed on these insects it is necessary constantly, otherwise they perish. Eggs of lice have the shape of an oval, pale yellow in color, up to 1 mm in size. After 4-9 days, a louse leaves the egg. A female louse living in the scalp of a person’s head has a size of 2.0-3.5 mm, a male – 2.0-3.0 mm. Females need to eat constantly, in small doses. For this reason, they can not live longer than one day. The louse has a female lick 3,75-5,0 mm long, male – 3,3-3,5 mm. Nits of this type of lice attach themselves to the tissue nap.

Symptoms of pediculosis

Diagnosis of pediculosis is simple: the patient’s skin has parasites, also on clothes, on hair and underwear are nits, the skin in the area of ​​lice localization is inflamed due to bites.

Another symptom of pediculosis is the endless itching – this is the skin’s response to lice bites. Itching is easy or intolerable, especially at night from lice. It happens that the patient does not even have a desire to scratch – this is a consequence of a chronic disease, a habit is developed. Rashes on the skin from lice bites occur after a while. In the beginning there is “itching acute dermatitis”, small bright red papules, vesicles. Further this process passes into chronic dermatitis, suppuration of papules occurs. Over time, there is a secondary infection, which is accompanied by anemia. With pubic and pediculous pediculosis, skin spots appear on the skin.

In case the patient has a severe stage of head lice, the head gets a bundle of tangled and stuck hair with the smell of rot. Depending on the location of lice and complications from this disease, there are also different symptoms. However, there are also patients who have lice around the body or whether there are dresses, pubic, and head parasites.

Causes of pediculosis

It is important to know that these insects do not fly and do not jump, but move with the help of running. This suggests that you can get infected with personal contact with the patient. Lice living in the head, move from person to person through the hair, especially the long ones. Mostly children are at risk, as they are most active, constantly in contact with each other during games, at school, at home, in children’s camps, in gardens, and they are changed by personal hygiene items – combs, towels. Children are hard to convince that you can not change caps.

A very remarkable fact that the cause of pediculosis can be an ordinary hairdresser. Such places as a bath, a swimming pool, a train, a hospital can also become a place of infection with pediculosis. Louse lice are transmitted somewhat differently than hair lice. Louse lice can be infected after a close household contact. Settling in the folds of clothing, lice pass to the skin of a person. Ill with pediculosis can be after using repeatedly dirty laundry or things. Pubic lice can be infected during sexual intercourse. However, they can only be infected by using someone else’s towels, clothes or underwear. Outside the body, the pubic louse lives only for a short time, not more than one day, although the eggs are more viable and live for a week. / / 3 / 3

Pediculosis is a very unpleasant disease. No one would be happy with such a situation when you talk with a man and catch a surprised and gaze at the hair on which lice stroll. For this reason, precautions must be observed. The most important thing in the prevention of pediculosis is personal hygiene, bed and underwear should be clean, since lice do not like cleanliness. Ironing the laundry should be thoroughly at the seams, since lice there lay eggs. Do not give anyone your comb.

It turns out that parasites are not very fond of the smell of lavender and tea tree. So if you apply this liquid to the nape of the neck and behind the ears, it will help to not catch lice. If, after all, you have had a pediculosis, then you need to disinfect towels, hats, bed linen, clothes, soft toys, then do not use them for two weeks. Without a human, the louse will live another week, if there were eggs, then the lice will leave in a week, so two weeks are enough to make sure that the lice are dead, since the parasites can not live without the blood of man. In order to be convinced of the presence or absence of lice, you can comb the head with a special comb over a light surface, after which everything will become clear.
