In 1988, health departments in the United States reported an all-time low of 225 cases of rubella. However, in 1989, the number of reported cases increased nearly twofold, and in 1990, an additional threefold. As of January 4, 1991, a provisional total of 1093 cases (0.4 cases per 100,000 population) had been reported to the National Notifiable Disease Surveillance System (NNDSS) for 1990—the highest total since 1982. This report summarizes the increase in rubella and congenital rubella syndrome (CRS) since 1988.
In 1990, provisional rubella reports were received from 38 states and the District of Columbia, compared with 29 states and Puerto Rico in 1989 and 23 states and Puerto Rico in 1988.* From 1988 through 1990, the incidence of rubella increased primarily in the West and Midwest. California, which reported half of U.S. cases in 1990, reported a nearly fourfold increase in reports from 1989 t0 1990. Rubella
