Characteristic of the scabies are tiny reddish nodules, which occur at typical localizations on the skin individually or flatly. Also typical is intense itching that gets worse at night.

Mite walks sometimes visible
Scabies are caused by mites. In some cases, the mite ducts below the uppermost skin layer are visible as fine, reddish-brown and up to 1 cm long lines visible to the naked eye. Then the diagnosis of scabies is relatively clear. This is often not the case. Either because the symptoms at first appearance (first onset) may still be quite weak. Sometimes the disease is expressed only by individual nodules on reddened skin. Or because the passages are becoming increasingly difficult to recognize over time, as they are quickly superimposed by scratch-induced, often purulent inflammation.
Since the symptoms itching and flaky skin as well as eczematous changes are also typical for other illnesses, the scabies are sometimes only recognized, if before the other possible causes were excluded. The diagnosis can only be valid when the mite detection has taken place.
