In 1969, the United States established its national rubella vaccination program. With the success of the program, 32 years later, reports of rubella reached record low numbers. To assess the achievement of elimination of rubella and congenital rubella syndrome (CRS) in the United States, 7 epidemiological criteria were used. Rubella cases reported to the National Notifiable Diseases Surveillance System from 1998 through 2004 and CRS cases reported to the National Congenital Rubella Syndrome Registry from 1998 through 2004 were analyzed. During 1998-2000, the median number of reported rubella cases was 272, whereas, during 2001-2004, the median number reported was 13. The incidence of rubella decreased significantly, from 0.1/100,000 population in 1998 to 0.005/100,000 population in 2004. Since 2001, 5 infants with CRS have been reported--3 were born in 2001, 1 was born in 2003, and 1 was born in 2004. The epidemiological evidence strongly supports the claim that rubella is no longer endemic in the United States. To prevent future rubella outbreaks and CRS cases, current strategies must be maintained.

1969年,美国建立了国家风疹疫苗接种计划。随着该计划的成功,32年后,风疹的报道达到了历史新低。为了评估在美国消除风疹和先天性风疹综合征 (CRS) 的成就,使用了7个流行病学标准。分析了向国家法定疾病监测系统报告的风疹病例1998年2004年和向国家先天性风疹综合征登记1998年2004年报告的CRS病例。在1998-2000年期间,报告的风疹病例的中位数为272,而在2001-2004年期间,报告的中位数为13。风疹的发病率从0.1/100,000人口1998年下降到0.005/100,000人口2004年。自2001年以来,已报告5例CRS婴儿-3例2001年出生,1例2003年出生,1例2004年出生。流行病学证据强烈支持风疹在美国不再流行的说法。为了防止未来的风疹暴发和CRS病例,必须维持当前的策略。
