In early 1982, 15 hospitals in Los Angeles County reported one or more serologically confirmed rubella cases among their employees. Secondary cases occurred at eight hospitals; overall, 56 cases were identified among employees, of which 28 were serologically confirmed. Testing of 2,061 employees revealed 1,770 (86%) with detectable antibody. A survey of 83 hospitals offering obstetrical services indicated only 42% (33 of 78) had an established rubella screening policy. Based on the results of this survey, the Los Angeles County Department of Health Services published recommendations for hospital rubella screening and immunization policies.
