Sarcoptes scabiei (Scabies)

Scabies, known as the seven-year itch, is a contagious skin infestation by the mite Sarcoptes scabiei. The most common symptoms are 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 certain areas such as the wrists, between fingers, or along the waistline. The itch is often worse at night.
