Scabies itself does not have a characteristic smell. However, the intense itching caused by the condition can cause the affected person to scratch their skin, which can break the skin and cause an infection. In some cases, this secondary infection can produce an odor. Additionally, scabies can sometimes be associated with a foul odor if the infestation is severe and left untreated for an extended period, as the mites and their waste products can accumulate on the skin. If you are concerned about a particular smell associated with your skin or an infestation, it is best to consult with a healthcare professional.
