What is scabies: a photo, symptoms, disease treatment

The name of the disease - scabies - have heard all, but clearly represent, what it is, not counting doctors, very few people.

However, although life mostly far from similar problems, knowledge never hurts, since cases of infection occur often and know best, how to recognize scabies and how to treat it. Photos from the typical cases of the disease - not the most pleasant sight, but, knowing, how it manifests itself, it will be easier to define it for yourself and loved ones.

What is this disease

The disease is highly contagious, ticks. Transmission of the parasite occurs very easily, in contact with a person already ill with, or with the things (it happens less often, with advanced forms of the disease).

Ill with scabies can be everywhere, where there is a crowd of people. Including kindergarten, school, even in a hospital ward.

The most rapid spread of the disease occurs within the family - it is the most common route of infection a few people at a time.

A person begins scabies, if the surface of his skin were females tick, or its larvae.

In order to understand at once, that the disease begins, correctly interpret the first signs of it, should know "habit" mite.

The habitat of the parasite - in the dermal layers, on the surface of a tick appears for further migration through the body. The danger in the sense of transmission of the disease are female - they are more males, their mouth structure adapted for movement within the layers of the epidermis. The front legs ymeyutsya sucker. Which enables movement on the surface of the skin and under it.

mite life cycle is divided into 2 phase: dermal and subcutaneous. Exactly 2 step allows to suspect the presence of disease even in the absence of external signs.

The mite is nocturnal, female gnaws night moves in the skin, It lays its eggs (the first half of the night). She then continues to eat, gnawing long channel. Therefore, in the evening and at night a man worried about severe itching. Then the parasites come to the surface for mating and dispersal of the skin surface. On lying quietly, the warmth of sleep a person ticks move very fast, to 25 mm per minute. Such activity may explain, why the majority of infections occur in sleeping a total bed. Day of rest insects, that can create the illusion of peace.

The eggs hatch larvae, which reach maturity, infiltrating the hair follicles. In this way, if not curing the disease, breeding cycle and resettlement ticks on the body may become a regular and infinite.

To expand the horizons! Adult mite has a lifespan of up 3 months, in the presence of tolerable conditions of existence of the female is able to give birth 150 million. individuals.

If human infection occurs mature individuals, to immediately start work on the resettlement of the skin and reproduction, developing this form of the disease.

  • Quickly appear scratches, are covered with a crust of dried blood.
  • Eruptions in the form of bubbles, often at the usual places parasite activity (on hands, legs). Inflammation is usually absent, bubbles themselves small, 1-3 mm (these are the first signs of defeat scabies).

Scabies no moves

This form of the disease appears briefly, after a while it becomes a typical scabies. It arises in the case of the larvae of the mite infestation, while signs are weak, small bubbles, very few of them. This state continues until the adults, as soon as they become sexually mature, Disease manifestations changes.

Upon contact with infected people, this form appears more often, so, if the family or collective cases are identified, We should not wait for symptoms Gain, and quickly begin treatment each person.

Scabies "incognito"

Complicated to diagnose disease, typical for individuals, having the habit of swimming at night. when washing, especially wool, from the surface are washed off all the parasites. Therefore, the symptoms are very weak, in most cases it can only be determined by a dermatologist. Even a very neat person can not get rid of them without special preparations.

It is called "cortical", "Krustoznaya". May develop in humans, who for some reason have a reduced sensitivity, or it is not. In these disorders in humans there is no itching, and the disease develops very intensively, Moreover, This type of mange is the infectious.

The reasons for the lack of sensitivity may be different:

  • limb paresis
  • treatment of hormonal drugs (it may change the degree of sensitivity)
  • diabetes
  • SPID

No worry, but, Consequently, emergency measures can lead to the formation of massive crust body, in their thickness, beneath them is a huge number of insects (to a million!). Especially damage seen in the hands and feet, These growths are painful, making limited limb movement. nails, hair, Skin color also damaged, which does not occur in a typical form of the disease.

itch limfoplaziya

This form is manifested reaction to the parasite, thus there is a thickening of the lymphoid tissue, increase nodules, appearance formations (knots) of lymphoid structures, which can cause anxiety, as itching.

Psevdosarkoz

May appear when the infection in other species of ticks, eg, in contact with sick animals, usually with dogs.

Then it can be itchy, bubbles - both in human scabies, but parasites are not embedded in the epidermis, There are no moves. Can be solved, that begins scabies, Symptoms of infection may occur on exposed parts of the body, but the development of the disease does not occur.

After termination of the contact with the source of mites symptoms quickly disappear, so that the planned treatment in this case is not required - the person is not a full-fledged master of many species of parasites, living animal.

Sick animals should be treated, after which time signs of defeat quickly disappear.
