How scabies is manifested - detailed information

An infectious disease that occurs due to a lesion by a parasitizing organism - an itch mite. It is manifested in the form of uncomfortable symptoms( rash, itching).To the extent of the microscopic size of the parasite, it can not be considered at all, therefore it is possible to determine the ailment only by the characteristic symptoms that begin to occur immediately after infection. Infect scabies can be in close contact with the carrier of the parasite or with his personal belongings. At the same time, the probability of infection by an itch mite from an animal is excluded, since the parasite is transmitted only from person to person.

Pathogenesis of the disease

Scabular itch or tick - this is how the scabies are determined in medicine, the dimensions of which do not reach even 0.35 mm.it can be exclusively under a microscope. This parasite differs in features of sex - the female body is more oval and, more importantly, much larger than the male. The disease is activated immediately after a direct hit on the skin of the parasite.

Itch reproduces itch very quickly, moreover, the male after mating is killed, and the female makes subcutaneous courses to lay eggs. Scabrous strokes are formed directly in the horny skin layer. Two days after laying eggs, larvae mature. It takes fourteen days for the development of the larva to fully develop into an adult capable of reproduction.

the help! The lifespan of one parasite reaches three months, during this period it is capable of producing six generations of new parasites.

Thus, in the absence of timely treatment, scabies can go into a complicated form of flow, since a large area of ​​the body will be affected by parasites.

In the morning and afternoon the parasite is not active, so the discomfort symptomatology appears only in the evening, when the female makes an itch. Dissolution of cells in the subcutaneous layer occurs with the help of a special enzyme contained in the saliva of the parasite. Consequently, on the skin, there are irritative processes in the form of rashes and redness - this is a response to the interaction of the subcutaneous layers with the products of vital activity.

At night, the mite leaves the skin outside to conduct the process of mating and hitting the new area on the skin. This explains the ease of infection when contacting bed linens infected or in direct contact with the patient.

The disease is in the incubation period for ten days. However, the appearance of rashes can occur much earlier, so you can react in time and prevent the defeat of all large areas of the body.

Risk groups

• preschool children, adolescents that are constantly in the team;
• people with limited freedom( places of compulsory treatment, places of detention);
• groups of people living in unhygienic conditions;
• people that have promiscuity.

Attention! Scabies are easily transmitted by close contact of people, when using personal belongings and household items of the infected. Especially infecting those who ignore the rules of personal hygiene.

Main symptoms of

There are several types of this disease, but the general symptoms are:

1. Intense itching, which appears closer to the night.
2. A skin rash appears on the skin.
3. If you use magnifying devices, you can consider an itch movement in the form of a gray-white subcutaneous stripe, at the end of which there is a nodule( the place of deposition of eggs).

One of the first signs is an unbearable itch, pronounced at night. The intensity of the itching is such that it can lead to a nervous breakdown or insomnia.

Burning and itching do not disappear throughout the disease, so the infected combs the affected areas, forming microscopic abrasions on the skin. Such damage is very dangerous, because through them can penetrate a fungal or other infection.

Caution! It is necessary to use an ointment that can reduce itching, as when combing eggs the parasite spreads to healthy areas of the skin, complicating the disease.

The main places for the localization of the parasite are the interdigital area, palms, groin, chest and abdomen, buttocks. It is very dangerous to run scabies - this is fraught with the development of abscesses and eczema. Scabies can also provoke furunculosis. Often the disease is accompanied by a complication in the form of allergic dermatitis. This means that the skin is formed pyoderma, that is, the rash is accompanied by a purulent process.

How to conduct an independent examination?

To perform the manipulation, iodine will be needed to treat the affected area. Due to this, the itch will be clearly visible on the skin( their length can reach one centimeter).If you hold a palpation, you can see an elevation above the skin. After an independent examination, you should contact a specialist to have the right treatment prescribed, depending on the type of disease.

Types of scabies lesion

Name of the disease	Image of	Short description
Typical scabies		To determine this type of disease, you can locate the specific area of ​​the rash - ulnar and knee joints, inguinal region, axillary zone. In addition, there is a classic symptomatology in the form of intense itching, the appearance of itch moves, small rashes. Apprehensions can be seen as a consequence of combing the diseased areas and getting through pathological microflora abrasions
Atypical scabies		When a person has strong immunity, the parasite can not fully reproduce and affect large areas of the skin. Consequently, the parasitic process is difficult. However, an atypical form of the disease is characterized by a minimum of symptoms. Often, an ailment is defined as scabies of cleanliness. At the same time itchy itching will be weakly expressed, and itching will not be visible. In the chest area there may be a rash in the form of vesicles. The peculiarity of this form is that it is difficult to diagnose, therefore the person remains a parasite carrier for a long time.
Nodular scabies		The human body reacts sharply to the products of vital activity of the parasite, therefore allergic reactions( rashes, redness) can be seen on the skin. Rashes will be knotty in shape, and located directly above the itch. After brushing, dry, coarse crusts form on their places. Rounded nodules can reach two centimeters in diameter and localize in the groin, thighs, buttocks, chest. It is thanks to them that it is possible to confirm a scabious lesion, since the moves will be hardly noticeable or completely absent. This is explained by the defeat not of a tick, but of its larva. The first manifestations are noticeable only after two weeks.
Norwegian scabies		The ailment is not common and is rarely seen in medical practice. The defeat occurs against the background of a weakening of the protective functions of the immune system. The complication of the disease lies in the fact that a large number of parasites accumulate on one part of the skin. Therefore, the symptomatology is pronounced: skin in the lesions is covered with coarse crusts and a lot of parasitic moves; on the skin, polymorphic eruptions are seen; there is an intolerable itch; may be a complication of a purulent infection; crusts can not be removed by themselves due to severe soreness; in the places of fallen off crusts are eroded. In the process of defeat, the feet, palms, and the head( namely, the hair part) may suffer. Such a complex form of the disease most often affects people who have HIV infection, alcoholics, people with a minimum level of immunity

Caution! You can not engage in self-medication scabies. After diagnosis, the doctor must determine the type of disease and, based on this, prescribe a therapy.

How is the diagnosis of scabies?

This parasitic lesion requires a number of laboratory tests. For example, to determine the tick and its larvae, a microscopic cut is made in the area of ​​the lesion( striation of the stratum corneum).

One of the most popular methods of diagnosing scabies is scraping with the use of lactic acid. Thanks to this substance there is an excellent loosening of the stratum corneum without consequences for the deeper layers of the skin. To carry out diagnostic manipulation, apply a small amount of lactic acid to the affected area( stroke or nodule) to act for five minutes. At the end of time, the upper skin layer becomes loose, which makes it possible to scrape it without difficulty. The collected material is examined under a microscope, which makes it possible to examine eggs, larvae and the parasite itself.
