Indigenous rubella and congenital rubella syndrome (CRS) have been targeted for elimination in the United States by the year 2000. Progress toward reaching this goal is monitored through the National Notifiable Diseases Surveillance System and the National Congenital Rubella Syndrome Registry. From 1969 through 1989, the numbers of annual reported cases decreased 99.6% for rubella and 97.4% for CRS. Following a slight resurgence during 1990-1991, the number of reported rubella cases reached record lows during 1992-1996 (annual average: 183 reported cases). This report summarizes the characteristics of rubella and CRS cases and outbreaks reported in the United States from 1994 through 1996 and provisional data as of April 18, 1997. The findings indicate sustained low incidence of rubella and CRS since 1992 and possible interruption of transmission of rubella virus in late 1996.
美国已将本土风疹和先天性风疹综合征（CRS）列为到2000年要消除的目标疾病。通过国家法定传染病监测系统和国家先天性风疹综合征登记处对实现这一目标的进展情况进行监测。1969年至1989年期间，风疹的年报告病例数下降了99.6%，先天性风疹综合征的年报告病例数下降了97.4%。在1990 - 1991年略有回升之后，1992 - 1996年期间风疹报告病例数降至历史最低点（年平均：183例报告病例）。本报告总结了1994年至1996年美国报告的风疹和先天性风疹综合征病例及疫情的特征，以及截至1997年4月18日的临时数据。研究结果表明，自1992年以来风疹和先天性风疹综合征的发病率持续较低，并且在1996年末风疹病毒的传播可能已被阻断。
