What causes scabies?

Scabies is caused by an infestation of the skin by the mite Sarcoptes scabiei. This microscopic ectoparasite burrows into the upper layer of the skin, leading to intense itching and a rash. Unlike infections caused by viruses, bacteria, or fungi, the primary issue in scabies is the presence of this particular mite, which feeds on skin cells and causes an immune response that results in skin irritation.

Understanding the specific nature of the cause is essential for effective treatment. Effective management of scabies typically involves the use of topical insecticides that specifically target mites, rather than treatments that might be effective against viruses, bacteria, or fungi, which are not the issue in this case. This highlights the importance of accurately identifying the cause of a condition in order to provide the correct intervention.
