Clinical Significance
Sarcoptes scabiei causes scabies which is recognized by a nocturnal itch occurring primarily on the webbing between the fingers spreading to the wrists, elbows, buttocks, breasts and external genitalia. This itch and accompanying skin eruptions are delayed for several weeks after the initial infection. The rash represents a sensitization to the bite which does not necessarily correspond to the location of the active adult female.
