Who's At Risk
Scabies is seen in people of all ethnicities, all ages, both sexes, and at all socioeconomic levels. The infestation is not caused by lack of personal hygiene but is more frequently seen in people who live in crowded, urban conditions. People at particular risk are those who are in crowded living situations, such as hospitals, nursing homes, and prisons. Though scabies is extremely contagious, it usually requires prolonged skin-to-skin contact with a person who is already infested. Limited contact, such as a hug or handshake, will not normally spread the infection. However, scabies is easily spread to sexual partners and to other members of the household. Even if a person does not yet have symptoms, he or she can pass the infestation on to other people. Less commonly, it may be spread by sharing towels, clothing, or bedding.
