Scabies - a skin infectious disease from the discharge of parasitic, characterized by a skin lesion of an itch mite, or itch (Sarcoptes scabiei). The tick-pathogen is discernible to the naked eye (under close scrutiny) as a point, white or yellowish, no larger than a poppy seed.
The high contagiosity of scabies in humans is explained by the short period of time for which the itch mite is able to penetrate the human skin. This time interval is 15-20 minutes.
At night, a female tick gnaws through the skin, and in the morning lays eggs. The life cycle of an itch mite is 2-8 weeks. Then the causative agent of scabies perishes and decomposes in paved courses. Outside a person, the mite is killed quite quickly. The activity of scabies at night promotes a high risk of infection of the whole family in case of using one bed.
In this article we will look at how man's scabies look, its symptoms and the first signs in the initial stage after infection with the tick. In addition, we will touch upon the topic of how to treat scabies at home, and what medications are able to cope with the disease as quickly and effectively as possible.
How can you get scabies, and what is it?
Let us consider in more detail what it is. The causative agent of scabies in humans is a special itch mite (a miniature insect living on the skin human), which easily tolerates low and high temperatures, is resistant to disinfection, endurance. Infection occurs in the process of personal contact with the patient, his things, in public places, sexually.
In the role of an infection carrier, the female of the scabies mite appears. Settling under the skin, she begins to make subcutaneous courses and lay eggs there. A few days later the eggs turn into larvae. In this form they will stay a week and a half, after they turn into an adult.
The disease is extremely contagious, its incubation period lasts up to 14 days. Enough of a fleeting touch of the skin affected by scabies man - and you can get infected, and scabies treatment is long and unpleasant.
First signs
We note the first signs of scabies, which determine this ailment. If this symptom is found, any dermatologist with absolute certainty will establish an accurate diagnosis:
The appearance of itch moves - they look like a small whitish strip up to 1 cm in length. Most often, the channels, laid with ticks, are located on the abdomen, buttocks, feet, in the armpit, on the palms and in the folds of the ulnar fold. Anxistent itching, worse at night. This is due to the increased activity of the female in the evening. Rashes and characteristic itching appeared in other members of the family after direct contact with the infected person.
In children scabies occur in a much heavier form than in adults. When diagnosing scabies, treating a child often involves removing parasites from all areas of the skin, including the face and scalp.
Symptoms of scabies
The incubation period of scabies has a duration of 10-14 days. After this time, the mite larvae reach the state of adult individuals and begin to multiply. But when a person has the first symptoms of scabies after infection - it's hard to predict. This affects the age of the mites that have got into the body and the speed of their spreading through the skin.
For scabies, there is an itch that intensifies at night, as well as paired nodular-vesicle rashes (see Fig. a photo). Scabrous strokes outwardly resemble thin, slightly protruding above the surface of the skin, strips that can go zigzagging and straight. Usually the scabies tick ends with a white and transparent bubble, in which you can see the body of the tick (white dot). In rare cases, itch can not be detected (this is called scabies without strokes).
The most popular places of the defeat of the scabies are the interdigital space, the abdomen, the lateral parts trunks, ulnar folds, the area of the mammary glands, buttocks, genitals, predominantly in men.

Diagnostics
In principle, for accurate diagnosis of scabies is enough and just a visual inspection. However, it sometimes requires microscopic confirmation that all symptoms are caused by a mite. To test for a damaged area of the skin, a drop of petroleum jelly is applied and then a scraping is performed. In the study of scrapes, either parasites themselves, or their products of vital activity, eggs and excreta are found.

Spontaneous scabies never pass and can take many months and years, sometimes exacerbating.
