Summary
Scabies is a highly contagious skin infection caused by the mite Sarcoptes scabiei. Scabies is spread through close physical contact with an infected person or by sharing clothing or bedding. Symptoms of scabies include severe itchiness and a pimple-like rash. Occasionally tiny burrows may be seen in the skin. These symptoms can be present across most of the body or just in certain areas such as the wrists, between fingers, or along the waistline. The itch is often worse at night. Treatment includes topical permethrin and oral ivermectin. Benzyl benzoate application is an alternative. It's also important to treat all close contacts, and to wash all clothing, bedding, and towels used by the infected person in hot water.
