Scabies - a contagious disease that occurs when entering the skin scabies mite, proceeds with severe itching and is characterized by skin lesions that are caused by the formation of the pathogen moves and scratches.
itch mite is very small in size: length 0.2-0.4 mm width 0.14 -0.35 mm, oval. Life expectancy is about a month. The larvae of mites and the males live on the skin surface. The female just pierce the stratum corneum of the skin, makes a move parallel to its surface, and which lays its eggs. The larvae of mites and then come to the surface of the skin, turning already here in the adult mite. Full development cycle takes about two weeks.
Regardless of the human itch mite can live for 2-3 days at room temperature, but at a temperature of 60C it would die already at 1:00, well, boiling, or vice versa - at temperatures below freezing mites are killed almost immediately.
scabies infection occurs through direct household contact with an ill person: a bed or underwear, towels, as well as through sexual contact. Often infection occurs through sponges and brooms in the bath. Less commonly, scabies is transmitted through a handshake. Children can be infected through toys.
The incubation period is 7-10 days.
itch mite makes low temperature, being boiled die only after 10 minutes, and is also resistant to many chlorine-containing disinfectants.


For scabies is characterized by a strong sharp itching, worse evening and night. Although the itching is an allergic reaction to the mites and their droppings. Therefore, when primary infection itch may take a week or more, but when re-infection reaction occurs in the very first day. On the skin noticeably eruption of small papules arranged in pairs-vesicular elements that are combed patients until bleeding point crusts and even linear scratching.
The most characteristic feature of scabies are mangy moves. In a place where female mites penetrated, there is a bubble the size of a millet grain, filled with transparent contents. Moving parallel to the skin, the female is doing itch move which on the surface of the skin looks as thin strips of grayish in length from a few millimeters to a centimeter. It was at this turn and the female lays her eggs. At the end of the itch is seen as a bubble, in which there is a female. Most often itch passages found on the skin of the hands, especially fingers, the wrist forward, as well as on the penis. Less likely to itch on the skin of the moves are the buttocks, abdomen, inner surfaces of hands and feet. In children, scabies may have elements on the palms, soles, and even the face. In adults, the same skin of the face, neck and interscapular area, underarms, palms and soles are not affected.


It has been estimated that in the absence of treatment for only three months is not human skin can appear six generations of the mite, and the number of parasites can reach 150 million individuals.
Intense itching leads to scratching of the skin, such as damage to the skin can easily become infected, which often leads to secondary infection.
untimeliness of treatment can lead to various complications, the most common are dermatitis and pyoderma, is less common microbial eczema and urticaria . There may be boils , impetigo and ecthyma. In addition, the itch can become complicated and sexually transmitted diseases, because the integrity of the skin in the genital area is also violated, that allows you to easily penetrate any infection.
Against the background of long-term presence of scabies or inadequacy of its treatment may have more and neuro-psychological problems.
