Dermatological diseases are a huge mass: sometimes they manifest similar symptoms, in other cases they are immediately and easily identified. The treatment is different for everyone, as the causes of the occurrence vary. In this article we will talk about such a disease as scab. This is a serious disease with a very specific occurrence. It is necessary to know exactly its symptoms.
Scabies is a contagious infection
Some skin diseases appear on the basis of nerves, others are provoked by a fungus, others are hormonal disruptions, and fourth are parasites. That's just the scab - this is the result of interference in the life of a parasite. It's called the scabies mite. He is very tenacious and dangerous. That is, the scab is nothing but scabies.
This disease is highly contagious, but you can only learn about infection a week after contact with the carrier of the parasite. The most extensive outbreaks of infection occur in the autumn-winter period. Pathogens are much more comfortable in the cool. In addition, sweata person has an antimicrobial effect: in the summer, this practically does not leave ticks the slightest chance. They simply cannot find a victim. Infection occurs by contact. That is, through touching the wearer's skin or his personal belongings. Wet places are considered the optimal habitat for the parasite. There he can maintain active behavior for up to five days.
Causes of occurrence
In developed countries, scabies itch is not so common, but it can still be caught. At risk are mainly children of preschool and school age. They have rather weak immunity. The scab appears as a skin rash in the most affected parts of the integument. This happens due to the reaction of the body to the penetration of the parasite and its saliva, which destroys the cell membranes. The disease progresses quickly and continuously, capturing more and more areas of the body.
The carrier is capable of infecting an absolutely he althy person at any stage. Then it can take a whole month until the first symptoms appear. For this, the tick must multiply sufficiently in the skin of the infected. And scabies will appear as an allergic reaction to the waste products of the parasite. Due to the fact that the mite 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
Scabies in people is manifested by severe itching inside the skin. It intensifies in the evening and at night. Large papules and vesicles characteristic of scabs do not form immediately, initially a rash appears, similar to urticaria. That is why people often confuse it with allergies, unaware of the existence of a harmful parasite in their body. The period when there are no symptoms at all lasts, as a rule, from several days to two weeks. However, the carrier can infect other people already at this time. Even before diagnosing a characteristic rash, scabs on the skin can be recognized by the various subcutaneous passages of the tick, which differ in color.
Scabies in children
Scabies on the body in children appear almost the same as in adults. But due to a weaker immune system, it is usually 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 according to the type of eczema. In this case, the child is already tormented not only by itching, but also by painful conditions of the skin. Due to concomitant infections, the lymph nodes are greatly enlarged, the skin above them swells, and the places where they are located begin to hurt. If the disease is started, there is a danger of blood poisoning, which threatens not only the he alth, but also the life of the child.
Scabies treatment
This disease does not relapse. But these parasites do not develop stable immunity in humans,This means that re-infection is possible. It is necessary to avoid contact with infected people, observe the provisions for the disinfection of personal items and clothing, and adhere to basic rules of personal hygiene.
Taking medications in accordance with the doctor's prescription is a prerequisite for recovery. Medicines that are applied to the skin must remain on it for at least 12 hours a day. Constant processing of nails is necessary, since a lot of pathogens accumulate there. Everyone who was close to the patient should undergo a course of drug prophylaxis. As a treatment, antiparasitic drugs are used in the form of rubbing, various ointments and other types of external medicines. Usually they already contain substances in their composition that relieve itching and pain, and also minimize allergies. On the front part, ointments with the least pronounced allergic effect are used. If you suspect a scab, be sure to contact doctors such as a dermatologist and parasitologist.
