Visual symptoms of scabies: what do they look like, and where are they found? Scabies can be on almost any part of the body, but often the hands are the first area affected. Scabies also particularly like to live in skin folds and crevices, such as those on the inside of the wrist.
People get scabies when the mite burrows into the top layer of skin to live and feed. When the skin reacts to the mite, an extremely itchy rash develops. This mite can travel from the infected person to another person. Most people get scabies from direct, skin-to-skin contact. Less often, people pick up mites from infested items such as bedding, clothes, and furniture. The mite can survive for about 3 to 4 days without being on a human. Worldwide, there are millions of cases of scabies each year. Anyone can get scabies. It strikes people of all ages, races, and income levels.
