Where does the lice from a person originally come from - the path of infection!

Despite the huge variety of different hygiene products used by modern people, they still can not 100% protect it from surrounding parasites. For example, lice can suddenly appear on the head, and cleanliness does not play a special role here. Moreover, pediculosis can develop in both a child and an adult.

But where do lice from a person originally come from? There are many wild enough misconceptions that can be heard even from educated people, so today we will conduct a small "illiteracy on lice" and consider the main causes of the occurrence of pediculosis.

The main reasons for the appearance of lice

This problem is very urgent, because these parasites, as a rule, appear suddenly. In fact, despite numerous myths, it is necessary to understand the main thing - lice are external parasites, and their carrier can only be a man. Lice feed on human blood, while the "owner" himself constantly suffers from discomfort, manifested in the form of itching and pain in the affected areas.

By the way, lice can be of several types:

• pubic;
  

  Pubic lice

• head;
  

  Head louse

• wardrobe.
  

  Linen louses( wardrobes)

Important Information! All these parasites are transmitted by contact method, and this can be not only direct interaction with the carrier, but also the use of his personal belongings( razors, combs, etc.).Through food or from animals, lice can not be transmitted.

And if we consider the problem of the appearance of pediculosis deeper, then there are several main reasons.

Table. Where do lice come from

Reason	Short description
Public places	These are potential risk areas. A good example is, say, children's institutions. Children are often infected with pediculosis in kindergartens and schools.
Water	Yes, water can really act as a source of infection, because lice can live in it for a while. That is why it is quite possible to pick up parasites in a pond with standing water, not only in the pool, but also in a rural lake.
Close contacts	As noted above, lice can be transmitted through human interaction. This can be, for example, kissing or sexual intercourse( more refers to pubic parasites), group games( mostly childhood infections).
Neglect of hygiene rules	Parasites are more likely to be found in those who neglect personal hygiene, live in unsanitary conditions.
Long-term moving	The risk of infection in such cases increases. And the point here is not only that there is not always access to the simplest hygienic procedures, but also that on the way you have to communicate with a large number of people, including with carriers of pediculosis.
Cohabitation of people	This refers to places where a large number of people live( summer camps, prisons, etc.).
Personal belongings of the carrier	Towels, combs and other things of the carrier of the disease, containing lice or nits, can also be infectious. Few people know that these parasites can live without air for up to 24 hours.

Important Information! According to statistics, lice are most often infected in the autumn and winter time, when people spend most of their time in enclosed spaces, actively contacting each other.

But, in principle, pediculosis can appear under different circumstances. So, it's enough just to stand next to the carrier in public transport so that the parasites crawl on the other person's hair. Yes, lice can not jump like fleas, but they quickly crawl( about 4 mm / sec.), And after hitting a new "master", they begin to actively bite it and multiply. Incubation period of lice, by the way, takes about three weeks.

. Misconceptions about infection with pediculosis

There are several myths that must be debunked. Let's start with the most popular.

Misconception # 1.Mud

You can safely say that these parasites appear mainly on the head. And people who comply with all standards of hygiene, are greatly surprised to find a pediculosis. As a rule, this is explained by the myth that "where there is dirt, lice appear there."We will not delve into the reasons for the appearance of such a point of view, because it is important to clean hair, which after washing have lost particles of dirt, grease and plaque, parasites are much better than in a polluted environment. The fact is that it is easier for them to get to food, that is, blood.

Misconception # 2.Stressful situations

Can pediculosis develop on a background of stress? Many are confident of this, explaining all the fact that on the skin of each person there are lice and nits that are in a state of hibernation and waiting for the right moment. A pier, roughnesses on a head are nothing, as accumulations of bloodsuckers. And when a person is excited, the flow of blood to the head increases, which leads to activation of parasites. Those begin to move, eat and, of course, actively multiply.

Important Information! Pediculosis can not develop as a result of stress, this statement has no any confirmations at all. Moreover, in the scientific world it is not even considered because of its absurdity and illogicality.

Misconception # 3.Corruption

This hypothesis has no right to exist, but it still has a lot of fans who think that pediculosis is supposedly the result of the influence of negative energy. In other words, a person may have lice due to a bad eye, while they themselves are harbingers of something bad.

It is also worth noting that when considering different kinds of opinions a la "people say" you need to connect critical thinking. Let's say parasites are really "sleeping" on your head, but then the question arises: how did they get there at all? In addition, pediculosis is not a hereditary disease, let some believe otherwise. It has been scientifically proven that there are no parasites under the skin of newborn babies. It is also proved that without human blood lice die after 48 hours. That is why the hypothesis of "hibernation" can be confidently called absurd.

How not to confuse lice with other dermatological diseases?

The signs of pediculosis are very similar to the symptoms of certain skin diseases.

1. Dermatitis .This ailment occurs against a background of nervous stress, and if a person has in addition contacted the carrier of pediculosis, but it turns out to be a very complicated, it would seem, picture. But in reality both problems are not connected with each other. Scabies .It is confused with the appearance of lice most often. Nevertheless, scabies are caused by a completely different parasite - the subcutaneous tick, and the disease itself differs from pediculosis by the absence of nits in the hair and visible traces of the bite.
2. Psoriasis .The symptom of psoriasis( incurable disease), as well as pediculosis, is a strong undulating itch. Quite often people think that they have contracted lice, up to the time of diagnosis.

How to identify lice?

The symptoms of pediculosis may appear after a certain time( up to 20 days) after infection. This is enough to make the parasites breed.

The characteristic symptoms of the disease include:

• severe itching at bite sites;
• skin irritation, scratching;
• white lumps( nits) next to the roots of the hair;
• untidiness of hair, less often - inflammation of hair bulbs.

In addition, with close examination, you can see in the hair and the parasites themselves.

If you do not take any measures, the disease will start and other symptoms will appear, such as:

• koltuny( hair that has stuck together or stuck together) on the head;
• sleep disturbance;
• boils, dermatitis;
• irritability;
• enlargement of the lymph nodes behind the auricles.

And if a person has all the symptoms of an early infection, then it's safe to say that he had lice. In this case, you should immediately begin treatment.
