One of the preventive measures of pediculosis is a thorough examination of the head.

It can be carried out independently at home or with the help of medical personnel.

This is the simplest procedure that does not require special skills.

But before proceeding to the inspection of the head, you need to have a clear idea of ​​what to look for.

How to understand that you have lice?

How do you know if you have lice or not? It is almost impossible to detect the initial stage of infection with lice. One or two insects do not cause a person any tangible discomfort. But when the population of parasites increases tenfold (under favorable conditions, this can happen in 10-14 days), then all direct and indirect symptoms will not go unnoticed.

Indirect symptoms of head lice

  1. Small rash. Lice regularly feed on human blood, per day they make 4-6 bites.

At the site of the insect bite, slight redness appears, the skin swells slightly, visually resembles a mosquito bite, only much smaller.

Multiple bites are often mistaken for an allergic reaction or dermatitis. When pediculosis is started, the papules (the site of a lice bite) combine and visually resemble large cyanotic spots. A distinctive feature of a louse bite is that the skin around the bite acquires a blue tint. Severe itching. Making a bite, the insect punctures the scalp and simultaneously with saliva injects a special enzyme into the wound, which prevents blood coagulation.

The human body perceives this enzyme as a strong allergen, therefore it reacts to it with severe itching.

Single bites do not cause tangible discomfort to a person, so it is difficult to detect pediculosis at the initial stage of infection. Multiple bites cause severe itching, which does not pass either after shampooing or after prolonged and intensive combing of the affected areas. Abscess formation. With intensive combing of the scalp, minor injuries and scratches form, and these are open doors for any infection.

Combing the scalp with dirty hands, a person himself can bring the infection into the wound, which will provoke the formation of ulcers.

Direct evidence

  • Live insects. Finding a live insect when inspecting the head is a great success. Lice quickly move over the surface of the scalp and hide in the hair.

Due to their small size (only 3-4 mm) and protective color (translucent, brown shade) they are almost invisible.

Under adverse conditions (air temperature below 10 degrees Celsius and above 40 degrees Celsius), lice fall into a stupor and move more slowly. Nits. Nits are cocoons with lice larvae or in other words their eggs. The female insect, as soon as it falls on the hair of a new victim, immediately begins to take care of the offspring and lays eggs.

Under favorable conditions, the female is able to postpone 4-6 nits per day. Each nit is very firmly attached to the hair shaft in the root zone (at a distance of 2-3 cm from the scalp).

Nits are not afraid of such procedures as washing your hair or brushing your hair with a simple comb. It is problematic to remove them, even many special chemicals aimed at combating parasites instantly kill adults, while they are not able to harm nits.

Nit has a light color, so it is very visible on dark hair. It is difficult to remove from the hair, in order to remove it simply with your fingers or nails you need to make an effort.

Nits can be either alive (in which there is a larva) or dead (the larva has already left the cocoon and turned into a young individual). To distinguish living nits from dead is quite simple: you need to put the nits between the nails of the thumbs and squeeze it. Living nits will make a distinctive sound, similar to a crunch, but dead no.

Principles of a self-conducted procedure

Inspecting yourself is not recommended, since this procedure is ineffective. At the initial stage of pediculosis infection, lice are localized in the occipital region of the head and temples. It is impossible to make a thorough examination of these parts of the body on your own.

But if it is not possible to attract a third party for examination, the following measures can be taken to detect lice and nits:

    Comb hair thoroughly with a special comb. To do this, you need to pour a little water into the bathroom or lay a plain light fabric on the floor and, tilting your head forward, carefully comb through the entire hair starting from the back of the head.

If there are insects or nits on the head, they will necessarily fall onto the fabric or into the water, or remain on the crest. Neutralize lice activity with a hairdryer. Air temperature above 40 degrees, can neutralize the activity of insects, under the influence of this temperature they fall into a stupor.

You can dry your head with a hairdryer for 10-15 minutes, and then comb out a comb with frequent teeth. Half-fainted lice are easier to remove from the hair and find themselves. Do this procedure over a light plain fabric or a container of water. Self-surface inspection of strands at the mirror:

  • stand by the mirror
  • point the lamp with bright light at a clearly visible area of ​​the head,
  • divide hair into small strands,
  • Carefully review the available strands for nits or lice.

How to check for lice. How to find out if you have head lice Pediculosis how to determine

Everyone should find out how you can get lice, so that he will be able to protect himself from unpleasant sharing:

  1. During close contact with the patient, in which there is contact with their heads or clothes.
  2. When using someone else's clothing, combs, towels, hairpins, hats, scarves, etc.
  3. During sexual intercourse, kisses.
  4. During a night's rest in someone else's bed.
  5. When traveling by public transport.
  6. While swimming in natural and artificial ponds, pools.
  7. When visiting public baths, saunas.
  8. Kids often become infected with head lice during games, after visiting summer camps, schools, kindergartens.

Recognize head lice

People can identify head lice on their own by the following signs:

  1. Immediately after infection, a person may not have pronounced symptoms. Slight itching may occur in different parts of the head, in its scalp.
  2. Over time, more pronounced signs of pediculosis begin to appear. Louse in order to get to the blood makes a puncture of the skin. In the resulting wound, it launches a specific substance that prevents blood clotting. As a result, the patient begins severe irritation.
  3. After the lice multiply, severe itching will not stop even after washing the head and the patient will constantly scratch his head.
  4. On the integument of the skin hidden by hair, pustules will appear, which in appearance are very similar to boils.
  5. If the problem is not given due attention, then pigmentation appears on the integument of the skin.
  6. Some people may develop allergic reactions.
  7. In the process of reproduction, females lay eggs, which they fix on the hairs using a special adhesive mixture. When examining the scalp, you will notice white blotches that resemble dandruff. But, unlike the dead particles of the epithelium of the nits, it is impossible to squeeze from the hair.
  8. Itching intensifies at night, as lice prefer to actively “eat” with the onset of darkness.
  9. After bites, blood spots appear on the skin.
  10. When pediculosis is started, patients may feel that something is crawling on their head.
  11. In small children, the same signs of pediculosis are observed as in adult patients. Children become irritable, often cry, wake up at night.

Symptoms of body lice

People can become infected not only with head lice, but also with clothes that live in the folds and in the seams of clothes and linen.

This type of louse lives most often in the pubic zone, namely in its scalp. Also, the insect can feel great, being in the cilia, in the eyebrows and in the armpits. Growth can occur during sexual intercourse, when visiting the pool, a common bath, when wearing someone else's clothes. People can suspect a ploschka by the following signs:

  1. A severe itching appears not only in the pubic area, but also near the anus.
  2. In places of bites, pigmented spots of a blue tint are formed.
  3. On the underwear, the patient can detect small spots that have a brown color, which are evidence of the activity of insects.
  4. After blood saturation, the pubic louse acquires either a brown or a dark orange hue. At this point, it can be seen on the body, even among dense vegetation.

Head lice detection methods

To confirm their assumptions about the presence of head lice, a person should do the following:

  1. You can use the mechanical method of destroying lice and nits. In this case, you will have to comb the hair with a special comb at least three times a week.
  2. In order to quickly get rid of unpleasant sharing, it is necessary to use special medications. Many drugs, presented in a wide range in pharmacy chains, are quite toxic, therefore, have a number of contraindications. To prevent the development of side effects, the patient should contact a medical institution and get medical advice. The specialist will select the most safe and effective drug that will help to quickly get rid of head lice.
  3. After the treatment, people who are faced with lice should rub over all their belongings, towels and beds. This must be done at the highest possible temperature. It is also necessary to carry out the sanitization of combs, hairpins and other objects that could have grown adults and their nits. Despite the fact that lice can not be outside their victim for a long time, for several days they are able to be present on pillows, upholstered furniture and other things.

A person can be “attacked” by three types of lice:

In laboratory conditions, these varieties interbreed, produce prolific offspring, however, in the natural environment, insects exist in isolation from each other.

What are the differences

A louse is a gray-brown bug with a size of 0.4-6 mm, with six legs. Nits - a louse egg coated with a special shell. The "cocoon" has a fusiform shape and a "lid" through which a ripened larva emerges from the capsule. Below is a belt wrapping an egg and hair to which it is attached. The length of the nits is 0.7-0.8 mm, the diameter of the capsule is about 0.4 mm.

Lice live outside a person’s head for no more than two days — they can last so long without food. If the ambient temperature drops to 10-12 ° C, pests can "stretch" longer - about ten days.

Fertilization and egg laying

Louse is capable of giving offspring, whose age is about two weeks. After fertilization by the male and “meal”, the female lays eggs. It happens like this.

  • Egg ripening. While the louse moves upward through the hair, the egg descends through the oviduct in the body of the insect, passing through the glands that cover it with a special composition.
  • Egg yield. By secretion, the egg, leaving through the anus, is attached to the hair at a distance of 2-3 cm from the root.
  • Attachment to the hair. After a few minutes, the shell becomes so strong that it is not even possible to remove the nits from the curl with nails.

Louse chooses free hair for laying eggs. On one lock there can be more than one nit, only if there are a lot of insects.

Larval development

In a cocoon, the larva develops in five to eight days. Ripening time depends on environmental conditions. For nits, the most favorable temperature is 33 ° C. When the indicator drops to 22 ° C or rises to 40 ° C, the development of the insect stops.

At temperatures above 45 ° C, the larva dies, at 0 ° C it can last two to three months. However, even in winter, the temperature of the scalp in a person rarely drops below 25 ° C, so lice can successfully develop all year round.

Converting to Adult

The larva emerging from an egg resembles an adult, but is smaller in size and is not able to give offspring. Within 14-16 days, the insect grows, during this period three molting occurs. After the latter, the pest is able to breed, which it does, almost immediately mating with an individual of the opposite sex.

Lice multiply on a person’s head very quickly. Each female, under favorable conditions, lays about ten eggs per day.

What is dangerous pediculosis for a person

  1. The risk of contracting dangerous diseases. Pests are carriers of typhoid, trench fever, but in modern conditions this is rare.
  2. The likelihood of wound infection. Lice leave bite marks on the skin through which infection can enter the bloodstream.
  3. Dermatological lesions. Traces of bites provoke the appearance of bluish spots, allergic reactions, sometimes - pustular formations and pyoderma.
  4. Discomfort Finding lice on the head is associated with constant itching and burning.
  5. Difficulty in social contacts. When communicating with other people, a person who has lice in his hair feels awkward. In addition, it is dangerous for others, since there is a high risk of infection.

How can I "pick up"

How do people get lice and how do I know if there are lice on my head? Doctors have figured out where lice come from in a person, and how they crawl from a "sick" head to a "healthy" one. Two pathways of pediculosis infection were identified.

  1. From person to person. Most often, insects are transmitted in this way. This happens if people share the same bed, sit close to each other.
  2. Through personal hygiene items and clothing. When sharing towels, combs, hairpins and rubber bands, pests also “travel” from head to head. You can get infected if you put on a hat, a jacket with a hood or other clothes that a person with lice wore.

Nits, unlike lice, can be transmitted from person to person in exceptional cases, as they are tightly attached to the hair.

"Risky" public places

You can pick up lice anywhere by close contact with an infected person or by using his personal belongings. Most often this happens in:

  • schools
  • kindergartens
  • public transport,
  • movie theaters.

Pediculosis can be infected even in places of public bathing, for example, in the pool. In poor areas of India, infection often occurs while swimming in the river.

Common myths

Some word-of-mouth information about lice is erroneous. Here are the five most common myths.

There is an opinion that lice may appear on a nervous basis. Oddly enough, this is partly true. There is evidence that insects are more likely to “attack” those who are prone to anxiety and worry. Such people have very pulsating blood, excessive sweating, and their body odor is attractive to insects.

How to detect uninvited "guests" ...

The very first sign of head lice is itchy skin. After a bite of a pest, a wound forms in which its saliva enters, causing irritation. When there are few lice, the itching is minor, it is rarely associated with the presence of insects. However, the more they become, the more intolerable these feelings are.

The appearance of itching does not mean infection with head lice, only the detection of insects and nits can confirm the diagnosis. Adult lice are quite difficult to see: they live on the skin and move quickly. Most often, nits are the first to be detected. You can see light capsules with eggs with the naked eye, they are especially noticeable on dark straight hair. Sometimes nits are mistaken for dandruff.

... and distinguish from dandruff

You can distinguish dandruff from nits on four grounds.

  1. Amount. The amount of dandruff is always approximately the same, while the number of nits increases day by day.
  2. Appearance. Dandruff flakes can be of various sizes, reaching 5 mm, the size of nits is approximately the same - not more than 0.8 mm. A closer look through the shell of the nits reveals a dark egg, the empty capsule has a yellow or gray tint. Dandruff is always uniformly white.
  3. Sound. If you press on the nits, you can hear a characteristic click.
  4. The quality of the "coupling". Dandruff can be easily brushed off with curls, while nits are firmly connected to the hair.

Symptoms of Lice

Lice, moving from an infected head to a healthy one, almost immediately begin to feed on human blood and multiply. Since their protein is foreign to our body, bites cause an allergic reaction, manifested by itching, which only becomes stronger and can lead to bloody combs. Особенно сильным он становится в вечернее и ночное время.

Кроме того, можно заметить следующие признаки:

  • мелкие высыпания на коже,
  • черные точки на коже – следы жизнедеятельности вредителей,
  • ощущение ползания по голове,
  • зуд не проходит после мытья волос,
  • sleazy look of hair.

Insects can be found in the occipital and temporal parts of the head, since it is easier for them to bite through the skin. You can also see a change in skin color.

How to inspect the head

Detecting lice can be difficult, especially if the hair is blond and curly, or there are not so many pests. You can watch on the Internet from the photo how they appear. Pictures and photos may not always show how lice spread. The only sure way is combing with a special comb with frequent teeth. They can be white and black. What the nit looks like can be examined under a microscope. But it is advisable to entrust the examination to medical staff, but you can carry out the procedure at home.

  1. Settle in a well-lit place.
  2. Comb the hair with an ordinary comb, separating the tangled curls.
  3. Comb one strand with a special comb with frequent teeth.
  4. Immediately after combing, wipe the tool with a white cloth or cotton pad: lice and nits, if any, on the head will be noticeable on a light background.
  5. To comb through several strands in this way.

How to detect lice?

Lice are fairly easy to detect if combing dry hair with a frequent comb, tilting your head over a white towel, bathtub, tablecloth, or something similar.

If a child has lice

(memo for parents)

Pediculosis (lice) specifically affects children from 3 to 12 years old, most often girls - because of long hair. Lice do not jump from a sick head to a healthy one. Lice creep ... The head louse itself can be brown, gray, and white, but nits (lice eggs) can be easily seen at the base of the hair closer to the scalp - it needs warmth! The louse lays its eggs on the warmest parts of the head - at the base of the neck , behind the ears, in a bundle under the ponytail elastic band, on the side of the head on which your child likes to sleep.

So, it happened: a child has lice! Let's drive the louse together. We go for drugs to the nearest pharmacy where you can buy Medifoks, Veda, Pedilin, Cheremic Water and other drugs. We act strictly according to the instructions! The product is applied in sufficient quantity (the surface should look “thickly covered with cream”) on the hair and skin (it can be rubbed into the hair roots), left for 10–40 minutes, depending on the dosage form and instructions. The head needs to be covered with a scarf, polyethylene. Then thoroughly rinse with warm running water with ordinary shampoo.

After this procedure, you need to rinse your hair with 5% r-vinegar and hold for 30 minutes. Wash your hair with shampoo again, rinse your hair well in running water, and then comb out nits and dead lice with a comb . Therefore, the advice - get a special frequent comb. Only combing out and personal hand-to-hand extermination will give a result. If necessary, this procedure is repeated after 7 days. Show special zeal in the fight against nits: one missed one - and everything went on a new one! Who will push the nits, remember: when crushing live nits with her nails, she clicks.

Yes, an important point - we are treating pediculosis with the whole family! Even if other lice were not found, pediculosis is difficult to detect at an early stage.

However, no treatment will help, no manual combing out, if we do not carry out a complete rehabilitation of everything that a pediculized child could come into contact with! Therefore, we wash all clothes, bedclothes in hot water (what cannot be washed immediately in a plastic bag and in the freezer, and in the winter time - on a balcony or veranda for 3-4 hours). All combs are washed and sterilized, hairpins, brushes, all hats are replaced (or they freeze and iron from the inside), the fleecy furniture is ironed with a hot iron, and the carpets are thoroughly vacuum cleaned. Moreover, do it simultaneously with hair treatment, otherwise neither one nor the other will give a result. And yet - pets do not tolerate pediculosis.

Inspect the baby's hair regularly (every 7-10 days).

Teach your child to use only personal hygiene products: combs and towels. Girls should braid their hair, especially when visiting crowded places.

When identifying a patient with head lice in an organized team

The patient (patients) is suspended for the period of treatment. Admission to the team is carried out if there is a certificate from the clinic, but with a mandatory pediculosis examination by a school doctor.

The whole family is being treated in the hearth! Of the medicines recommended "Medifoks", shampoo "Veda", "Cheremic water." In addition to treatment, bed and underwear (washing, ironing) and outer clothing are treated with cold (hats, coats, and fur coats are kept for 3-4 hours on a balcony or veranda in winter).

In the class (group) where the patient (s) is identified, a parent meeting is held with a notification of the case (s) of pediculosis, since in families, parents must examine children every 1-2 days for lice.

A dysfunctional team is set up for monthly medical supervision (a health worker conducts a routine examination of the entire class or group weekly).

That there was no flash in the team

If pediculosis in a child is detected by medical workers, educators or educators, parents are informed with recommendations on how to treat the child for pediculosis. Admission of children to a kindergarten or school is carried out only after sanitation from lice and, most importantly, from nits.

Activities carried out in child care facilities should be aimed at creating sanitary conditions that prevent skidding and the spread of head lice. Responsibility for organizing pediculosis examinations in organized teams lies with the medical staff and the administration of the institution. Inspections for lice are carried out quarterly at school and every month in a children's preschool team. However, if pediculosis is detected in the school (kindergarten), the frequency of examinations increases (up to 1 time in 7-10 days).

Admission to the team after treatment occurs only if there is a certificate of the child’s rehabilitation from lice. Dermatologists give it only if there is no nits at all that some parents are outraged. “This is dandruff! And I won’t treat the child! And I won’t go for help! Tomorrow he will come to school - and try not to accept him! ”- recently one of the parents was indignant. With this attitude to the problem, pediculosis cannot be exterminated, because if your child is not treated radically, he can infect other children in the class or group.

Infection of children with pubic lice is a rather exceptional phenomenon and occurs in isolated cases (for example, from infected parents, and sometimes even in public pools).

The photo below shows the head lice on the baby’s hair:

Pediculosis itself causes multiple unpleasant symptoms in a child. Most often, the disease is characterized by:

  • itchy in places
  • the appearance of characteristic reddish bite marks
  • the appearance of gray-blue spots on the skin
  • pustular skin lesions.

Pustular lesions are usually already the result of combing of bites of lice and getting into the comb of secondary infections. If untreated, the development of the disease can go further and lead to ulcers and pyoderma.

The following photo shows characteristic crusts at the sites of combing when the head of a child is infected with lice:

In the video, Dr. Komarovsky details how to determine the presence of lice in children. To do this, you can use a simple table lamp - with its light, the nits in children’s hair become especially noticeable:

Signs of Lice

Suspecting pests, it is necessary to conduct a thorough examination of the head. Most likely, it will not be possible to see the insects themselves, but their eggs, called nits, will be clearly visible on the hair. Outwardly, they look like grains of rice, so firmly planted on each hair that it is not possible to remove them.

Lice Detection Methods

The method of combing hair with a frequent comb over a sheet of clean white paper is recognized as effective. Hair needs to be wet and combed over the paper, moving from the back of the head to the forehead. One or two pests will certainly fall onto the paper.

You can ask a relative or acquaintance to carefully examine the hair in the light of a bright lamp - nits are easily detected along the entire length of the hair.

Lice prophylaxis

The best way to prevent the disease was and remains to prevent contact with an infected person. No need to use other people's combs, towels and personal items. In a new place you need to require clean bedding.

The danger is represented by small crowded ponds and pools - lice are not afraid of water. When swimming, it is appropriate to use a hat.

Preparatory stage


  • lamp with bright light
  • magnifying glass (magnifier),
  • a comb with frequent teeth.


  • Cover the floor with a plain light cloth.
  • If the inspection will be carried out in the bathroom, you need to get a little water.

A patient:

  1. Cover the patient with a light plain fabric from the shoulders and below. So that when parasites fall out, they can be detected and neutralized.
  2. Dissolve the hair.
  3. Comb and lay evenly so that the locks do not get tangled.
  4. Divide the entire hair into small curls.

A proper thorough examination of the head for pediculosis can be carried out only by an outside person, it is impossible to produce it yourself.

Step-by-step instruction

  1. An outsider, armed with a magnifying glass, carefully scans each strand of hair along its entire length.
  2. The strands are separated by a comb or comb with frequent teeth.
  3. Inspection should begin from the occipital part, then go to the temporal part, the crown and bangs are last seen.

Subsequent disinfection

  • After inspection, you need to boil a comb or comb (inspect it with boiling water or lower it in alcohol).
  • If lice or nits are found, the fabric must be washed in water above 40 degrees, and after drying ironed on both sides.
  • The patient’s clothes (when lice and nits are found), also need to be washed in hot water (above 40 degrees) and ironed.

Medical checkup

It is performed by a medical worker (nurse or doctor) in all places of a large concentration of people (sanatoriums, schools, kindergartens and so on).

A medical examination is a planned event, which, according to sanitary-epidemiological acts, is carried out regularly.

According to paragraph 3.12 of SanPiN 3.2.1333-03, the following population groups should undergo regular inspection of lice:

  1. Children in boarding schools - once a week.
  2. Hospital patients - upon admission to the hospital for treatment.
  3. Pupils of schools and preschool institutions (kindergartens) - once every three months.

Inspection of the head for pediculosis, it is recommended to carry out regularly. This is the easiest and fastest way to detect parasites and start treatment on time.

About lice and scabies

The photo below shows the head of a child infected with lice, nits are clearly visible:

Head lice in children look like tiny light bugs swarming in their hair.

Almost always, a child becomes infected with lice only in a collective from another child or adult. Lice are most actively distributed in kindergarten and school, where children constantly participate in games and fights, use toys and household items together.

“Lice appeared in our kindergarten. Moreover, the child brought infection from there, we treated her, they informed the director of the kindergarten, and two months later - a new infection. And so - three times! Once after being infected at home, a second child became infected from him. Can you imagine - lice in a child at 2 years old! He also has really no hair! We no longer knew where to complain, we wanted to leave the kindergarten. Until they wrote a complaint to the sanitary and epidemiological station. I don’t know who called the director there, but already on the second day a team of doctors from the regional center came to the kindergarten, found several children who had lice constantly, forbade them to be taken to the kindergarten. And that’s it. After that, the child was never sick. "

You should always remember that the peak of infectivity in children in kindergartens falls at the beginning of autumn, when infants infected during the summer give their lice to the rest.

After the autumn scandals, everything is usually treated, and until the next spring there are only a few precedents for the appearance of lice in kindergarten.

In the photo there are several lice:

For comparison - a photo of a tick (note that it has 8 legs, and lice have only 6):

And in the next photo - a bed bug:

A louse accidentally found on clothes differs from bedbugs in small size and light color, and from fleas - in the same light color of the body integument and inability to jump.

The following remedies are usually used to combat lice in children:

Before deciding what exactly to poison lice in a child, you should find out about the possibility of using this or that remedy in children of the corresponding age. Pediculicidal sprays for children are usually not used because of the danger of insecticide getting into the respiratory tract. The only exception is Nyuda spray, which contains no toxic substances.

The procedure for removing lice in a child

Children should not treat their heads with strong toxic drugs with an ovicidal effect, and therefore part of the nits on the hair will often remain alive. They are either combed out with a comb or the larvae emerging from them are destroyed a week after the first treatment of the head.

For a child, you can pre-treat the head with a solution of citric or acetic acid. These agents weaken the attachment of nits to the hair. It is only important to observe the correct concentration of the solution.

“At first I didn’t even know what to do if the child had lice. I didn’t even think about kerosene, so as not to poison him. I did not dare to buy any kind of chemical shampoo. But the comb helped me. I bought LiceGuard, for a week I combed my child’s head, and fainted from these nasty things. But combed out! Highly recommended now Nyuda, but I have not tried it. They say it is safe for the child. "

Toxic remedies for lice can not be used as preventive.

Today, a good remedy that can be used for prevention is a remedy for Nyuda lice, which does not contain substances toxic to the child.

Prevention of child lice infection

It is difficult for children, since it is usually difficult for a child to achieve compliance with all necessary hygiene rules. However, in any case, the following measures can reduce the risk of a child becoming infected with lice:

  • To instill in the child the rules for using his clothes and hygiene products.
  • To teach children not to come in close contact with their peers.
  • Avoid places where infected people may appear.
  • Do not let the child play with children who have signs of lice (tangled dirty hair plus frequent scratching of the head).

It seems that the symptoms of lice are so specific that it is difficult to confuse them with another pathology. However, in some cases, the diagnosis of pediculosis gives a false positive or false negative result, so sometimes it is possible to determine pediculosis only in the specialist’s office.

First symptoms

A louse without a carrier can survive a week. During this time, she finds a victim who soon has the first signs of head lice, or dies. There are three types of lice in humans:

  • headache
  • wardrobe
  • pubic.

Adults or children who discover the first signs of lice on their head should be checked by a health professional.

Pediculosis is a contagious disease, so everyone who has contacted an infected person will have to be examined.

Diagnosis of the disease

If children are more likely to suffer from lice on their heads, then the adult population is more susceptible to infection with pubic lice. Understanding that lice appeared in certain intimate places, a person is often shy and prefers to be treated independently, but this leads to the progression of the disease and to more complex treatment.

As a rule, platypus, or pubic lice, is transmitted from one sexual partner to another. However, it was necessary to diagnose pubic pediculosis that occurred after visiting public saunas or pools, since lice can live 2 days in water, a humid environment is most favorable for them.

How to understand that you have lice in the intimate area? The defining signs of pediculosis in adults are as follows:

After self-identification of lice of any type, it is advisable to undergo a medical diagnosis. It is very important to distinguish the signs of lice on a person’s head from the manifestations:

  • seborrheic eczema
  • dermatitis
  • psoriasis
  • neurodermatitis.

The specialist can use additional hardware methods for making a diagnosis. To diagnose lice, a Wood lamp is sometimes used. How to detect lice in a child and adult? The algorithm for examining whether a person has lice is as follows:

How to determine the development of complications?

It is not difficult to exterminate blood-sucking insects, provided that the rules for disinfection and proper use of drugs are observed. As soon as there are signs of lice, you should immediately contact specialists for help. Pediculosis is fraught with serious complications in case of improper treatment or its complete absence:

Unfortunately, everyone can get lice. You need to be alert and not to believe the myths prevailing in society:

При обнаружении первых симптомов педикулеза (гниды в волосах, сильный зуд) необходимо провести дезинфекцию помещения, одежды, игрушек, обуви и постельного белья, а также посетить педиатра или дерматолога. Чтобы исключить заражение лиц, которые контактировали с зараженным вшами человеком, их необходимо осмотреть дополнительно и провести профилактическое лечение.
