What is scabies caused by?

Scabies is caused by an infestation of the skin by the itch mite, specifically the Sarcoptes scabiei. This microscopic mite burrows into the outer layer of the skin, leading to intense itching and a rash. The condition is highly contagious and can spread through close personal contact or shared bedding and clothing.

Understanding that scabies is caused by a mite rather than other types of pathogens like viruses, fungi, or bacteria is important for proper diagnosis and treatment. Unlike infections caused by bacteria or viruses, which may require antibiotics or antiviral medications, scabies is typically treated with topical scabicides that specifically target the mite. Recognizing the correct causative agent is crucial for effective management of the condition.
