I sleep in a bed, on which the sleeping patient scabies - prepare for the visit to the doctor. The sources of the disease are mattresses and pillows in trains and hotels, private rented accommodation. Infection can occur if you are buying a new thing, not had washed her, and before that it tried on a patient with scabies people.
Set the exact source of infection iscomplicated. The incubation period lasts from 2 to 6 weeks during the initial infection, and at repeated - from one day. Do not think that scabies can be picked up only in Russia. The disease is an international and state borders are not an obstacle.
The main symptoms of the disease are cutaneousitching, worse in the evening and at night (this is not only a warm bed, but the fact that the mites are nocturnal). There are small pink nodules with a bubble and bloody crust on the top (see. Figure). In addition, the skin may appear a different shape of the band and abrasions from scratching, often joins pustular skin diseases. This greatly complicates the detection and disease can lead to complications. Severe itching leads to insomnia, malaise.
The female mite penetrates the stratum corneum andlays there itch moves, which lays up to 50 eggs, out of which 3-7 days are formed larvae. The transformation of the larvae mature ticks lasts up to several weeks.
Scabies mites penetrate typically thinnerskin, so eruptions are located in the interdigital folds of brushes on the flexor surfaces of arms and legs in the waist, abdomen, buttocks, the breasts in women, genital organs.
