In uncomplicated cases, easily detect chesotocnah moves in the form of a grayish-white winding S-shaped lines with a length of a few millimeters, especially noticeable after lubrication of iodine or paint. The female of the mite is located in blind end of turn, in the area of small bubble, where it is easy for removing, removing the lid bubble with a razor or curved scissors. In addition moves in uncomplicated scabies, are observed in typical places papules-vezikuleznaya rash, point and line scratches. Itching with scabies is rapidly increasing at night and only in rare cases does not bother patients (scabies apruriginosa).
