Mentally retarded hepatitis-B surface antigen carriers in NYC public school classes: a public health dilemma.

The placement of retarded children who have been institutionalized and are asymptomatic hepatitis-B surface antigen carriers into public school classes for the retarded has caused controversy and presented the New York City Health Department with an unusual medical-ethical dilemma. In this situation, the cost of interfering with deinstitutionalization, an important social advance, must be balanced against the benefit of controlling the unquantified but real risk of transmitting a potentially serious disease. The Health Department guidelines for managing this problem recommended serological surveillance, promotion of classroom hygiene where possible, and teaching of carriers in classes separate from their susceptible peers. A federal court disallowed the cohorting provisions of these guidelines. Changing policies and practices towards the mentally retarded, such as deinstitutionalization, raise important public health issues which will have to be faced by the involved communities.
