Scabies are caused by itch mites (Sarcoptes scabiei), which can attack humans through a variety of ways. The mite relies on humans as hosts and can only survive in a different environment for a short time. An itch mite is up to 0.5 millimeters in size and roundish. It needs oxygen like other mites, which is why it always stays on the skin or only in the first layer of skin. It feeds on lymph and skin cells.
While the male mite mites settle on the uppermost skin layer, the female mites drill passages into the horny layer. There they dig passages, at the end of which they lay their eggs. The reddish lines of the corridors can be seen on closer inspection, sometimes they are missing. she always close with the mite hill, which can be recognized as a red nodule at first glance. The human body reacts to the mite infestation smallest inflammation of the skin, which are getting worse from the scratching. Itching mites multiply very quickly, which is why, depending on the type of mite, after just a few weeks large parts of the body can be affected. Dross is not dangerous.
Scabies can be transmitted through sexual intercourse. Therefore, the disease is one of the sexually transmitted diseases.

Mites need a warm climate to get around. Therefore, the itching occurs especially at night under the warm duvet.
In addition to the classic, common scabies, there are special forms that bring depending on the severity lighter or more severe symptoms. Here is an overview of the most common forms.
|Type of scabies||description|
|Well-groomed Scabies (Scabies incognita)||Here are often missing the mite mound and the itching occurs supposedly without cause. This particular form often shows in people who bathe often.|
|Granulomatous scabies (Scabies granulomatosa)||Here, red to brown nodular inflammations form, which reach into deeper skin layers. They often persist long after the end of treatment and are believed to be due to mites that have reached deeper layers of the skin.|
|Scabies crustosa||Particularly severe form of scabies, which occurs especially in immunocompromised people (the elderly, babies and children). The infestation is very strong, the scalp may be affected. It is also a transmission over objects possible. Even after a successful treatment, individual itchy areas may persist.|

- belly button
- Chest and armpit area

- Scotch tape demolition: One of the intact mite mounds on the skin of the patient is slightly greased. Then the physician sticks an adhesive strip on the affected skin and tears off the tape with a jerk. This is how mites or larvae stick. Under the microscope, the attending physician examines the adhesive strip and can finally diagnose the scabies.
- Microscopic examinationThe doctor opens one of the nodules in which the female mite sits with its eggs and larvae. He scrapes out the mite mound and examines the material under a microscope.
If the scabies occur again, the immune system reacts faster and the itching occurs after a few days.
