What is Scabies primarily caused by?

Scabies is primarily caused by an infestation of the human itch mite, scientifically known as Sarcoptes scabiei. This microscopic mite burrows into the top layer of the skin, leading to intense itching and irritation as a result of the body's allergic reaction to the mite's presence and its waste products. The condition is highly contagious and can spread through close physical contact, making it particularly relevant in settings such as nursing homes where residents may be in close quarters. Understanding that scabies is caused by an itch mite emphasizes the importance of proper hygiene and infection control measures to prevent outbreaks in communal living situations.
