Korosta is ... Reasons, treatment

Dermatological diseases are a huge mass: sometimes they show similar symptoms, in other cases they are immediately and easily determined. Treatment at all specific, as well as the causes of the occurrence are different. In this article, let's talk about a disease like a scab. This is a serious illness with a very specific appearance. It is necessary to know exactly its symptoms.

Korosta is a contagious infection

Some skin diseases appear on the nerves, others are provoked by a fungus, third hormonal failures, and the fourth parasites. That's just the scab - this is the result of interference in the life of a human parasite. It is called an itch mite. He is very tenacious and dangerous. That is, the scab is nothing more than scabies.

This disease is very contagious, but it is possible to learn about infection only a week after contact with the carrier of the parasite. The most extensive outbreaks of infection occur in the autumn-winter period. Agitators are much more comfortable in coolness. In addition, the sweat of man has an antimicrobial effect: in summer it practically does not leave a tick for a tick. They simply can not find a victim. Infection occurs by contact. That is, through touching the skin of the carrier or to his personal things. The most suitable habitat for a parasite is wetlands. There he can keep active behavior for up to five days.

Causes

In developed countries itch is not so common, but still it can be picked up. At risk are mainly children of preschool and school age. At them weak enough immunity. A skin rash appears in the most affected parts of the veil. This is due to the body's reaction to the penetration of the parasite and its saliva, which destroys the cellular membranes. The disease progresses quickly and continuously, capturing all new areas of the body.

To infect absolutely healthy person the carrier is capable at any stage. Then it may take a month before the first symptoms appear. To do this, the tick must multiply enough in the skin of the infected. A scabies will appear as an allergic reaction to the products of the vital activity of the parasite. Due to the fact that the tick forms numerous channels in the skin and causes scabies, a person begins to actively comb the damaged areas. There is a risk of formation of pustular wounds.

Symptomatics

The crust in humans manifests a strong itch inside the skin. It intensifies by evening and at night. Characteristic for the scabs are large papules and vesicles do not form immediately, initially there is a rash, similar to hives. That's why people often confuse her with an allergy, without suspecting the existence of a harmful parasite in her body. The period when there are no symptoms at all, usually lasts from a few days to two weeks. However, the carrier can infect other people already at this time. Even before the diagnosis of a characteristic rash, the scab on the skin can be recognized by various subcutaneous tick movements that differ in color.

Korost in children

The crust on the body in children is almost the same as in adults. But because of weaker immunity, usually it is accompanied by additional infections. This greatly complicates the condition and treatment of a small patient. In children of the first year of life, this disease manifests itself as a common urticaria, because of this, it is problematic to diagnose the disease in time. There are signs of parasites in the buttocks, sides and face. With a long course of the disease, skin lesions develop as eczema. In this case, the child is already tormented not only by the itching, but also by the painful conditions of the skin. Because of the concomitant infections, lymph nodes greatly increase, the skin swells over them, and the places where they are, begin to ache. If the disease is started, there is a danger of contaminating the blood, which threatens not only health, but also the life of the child.

Treatment of scabies

Recurrence of this disease does not happen. But the resistant immunity these parasites do not produce in humans, therefore, repeated infection is possible. It is necessary to avoid contact with infected people, observe the disinfection of personal items and clothing, and adhere to the basic rules of personal hygiene.

Taking medications in accordance with the appointment of a doctor is a prerequisite for recovery. Medicines that are applied to the skin should stay on it for at least 12 hours a day. Necessary treatment of the nails is necessary, since the mass of pathogens is accumulated there. Everyone who was near the patient should undergo a course of drug prevention. As a treatment, antiparasitic preparations are used in the form of rastrok, various ointments and other types of medicines for external use. Usually they already contain substances in their composition that relieve the itching and pain syndrome, and also minimize allergies. On the front, ointments with the least severe allergic effect are used. If you suspect a cow, be sure to contact a doctor, such as a dermatologist and parasitologist.
