Head pediculosis. Myth or fact?It is known that a pediculosis - a disease with impressive history. It is possible for this reason it is surrounded with the most various myths. At the same time many of them were fixed in consciousness of people very with firmness. The dermatologist, the expert of the “Happy Childhood without Pediculosis“ program Oksana Kozhevina will help to understand what of these facts have under themselves the basis and what - are only popular beliefs.
Where and how to catch louses?
Myth 1. Louses can jump from the head on the head.
of the Louse - small wingless insects, they cannot fly and jump as it is considered to be. But they very quickly move on hair as on pads they have special hook-shaped claws which they strongly cling to hair including at direct contact the head to the head. To catch a head pediculosis simply being in one room with the person infected with louses it is impossible if at the same time not to contact to it in the above-stated way. However there is a chance “to pick up“ louses in public transport, in particular in hours “peak“ when density of people is very high and people are very closely to each other located. The risk of infection with head louses at people with a long flowing hair is especially big.
Myth 2. It is more than chances to ache with a head pediculosis at those who seldom wash the head, do not follow the rule of personal hygiene.
Purity of hair, as well as hygiene in general, in any way do not influence an opportunity to catch a head pediculosis. At the same time long time was considered that this problem is peculiar to the people leading an asocial life. Really, they make “risk group“ not only on head, but also on a clothes pediculosis. But nevertheless frequent cases of a head pediculosis register also against favorable socially - economic conditions. For the last decades the pediculosis often meets in economically developed countries.
Myth 3. It is possible to catch louses, swimming in the pool, the pond / small river or any other reservoir, and also from animals.
In spite of the fact that louses are capable to remain live in water about two days (at a temperature of +17), to catch head louses in the pool, when bathing in a pond, the small river or any other reservoir as it was shown in various researches, it is improbable.
Also it is impossible to catch louses and from pets as it is vidospetsifichny parasites. The person can have no cat`s louses. Therefore, having found them in the child, you should not process pets means from louses and vice versa.
Myth 4. Louses are carriers sypny, or returnable, typhus and other serious diseases. to
It is proved that louses are not carriers of serious infections, but, nevertheless, the itch of head skin can bring to the person notable discomfort. The matter is that louses quickly enough breed. Growth of number of these insects and increase in quantity of their stings leads to emergence having combed, and they in turn can serve as entrance gate for secondary infections, including regionarny lymphadenitis (increase in cervical lymph nodes) and allergic reactions.
Whether you know? Children catch
a head pediculosis more often than adults.
Really, most often head louses occur at children aged from 5 till 12 years. Unlike adults, they are much more mobile and sociable, spend in contact games much time, are secretive “on an ear“. Besides children willingly change headdresses, hairpins for hair and, without reflecting, use the general hairbrush. Especially often infection happens in children`s camps and in other places of summer holiday where a large number of children at the same time stays. In this regard health workers in kindergartens and schools without fail examine all children at the beginning of September on a pediculosis to stop further distribution of a disease.
Myth 5. Louses can appear because of nerves. the Nerve strain and a stress are not
the reason of emergence of a pediculosis at all. It is impossible to catch louses without contact with the carrier of parasites. Because of nerves there can be only symptoms similar to that which arise at a pediculosis, for example, a skin itch.
How to struggle with louses?
Myth 1. To get rid of louses, it is necessary to put all things in a plastic bag, to leave them in a bag for several weeks or to move away them in the refrigerator.
Some time ago it was very widespread recommendation. However it is known that louses live only on indumentum of the head of the person, and without it cannot longer live, than 48 hours. For this reason rather just to vacuum those surfaces with which the person who got sick with a pediculosis had contact, and also to wash its things in hot water.
Myth 2. To treat children for a pediculosis folk remedies more safely and more effectively.
Initially use of such folk remedies as vinegar, cranberry juice or broths of herbs, was popular in the basic because there were no other means. But it is important to know that, for example, vinegar does not kill adult louses, and destroys only substance which the female pastes eggs to a hair. Also chemerichny water is not really effective. Besides, it is quite toxic, and from its action only a half of louses perishes, all eggs at the same time remain viable. As a result the survived individuals breed again. And in spite of the fact that kerosene effectively destroys louses, it negatively influences skin and hair therefore its use can be hazardous to health of both the child, and the parent who processes his head.
Whether you know?
of the Louse can be steady against some pedikulitsidny means.
Since 80 - x of the XX century as a result of mutations at louses resistance to permethrin - one of the insecticides which are widely used at a pediculosis operating on nervous system of insects begins to be formed. It considerably reduced efficiency of such preparations. However among traditional insecticides still keep activity concerning head louses preparations on the basis of substances from other chemical groups. In the last decade there was a new effective group of pedikulitsid presented by the means containing silicone oils - dimetikona. At small concentration of dimetikon also mineral oils (Izopar, Klearol) are their part. Such means work physically - the substances which are their part interfere with breath of insects and break their water exchange. To them at louses stability does not develop, and besides they are nontoxical for the person.
to Parents it is important to i to understand
that louses - it is not a shame and the more so not a reason for quarantine in kindergarten where the child goes. The main thing to find them in time and to correctly pick up pedikulitsidny means which quickly and effectively will help to cope with a problem. It is also important to tell the child about rules of hygiene which minimize risk of infection with this disease.
