Measles is a highly contagious viral illness which once affected more than 95% of persons in the United States. Since licensure of a safe and highly effective vaccine, measles incidence has fallen to less than 1% of prevaccination levels. A relative resurgence of measles during 1989-1991, however, focused attention on the need to maintain high immunization levels, particularly among preschool-aged children in urban areas. Improved vaccine coverage levels and a second-dose strategy to eliminate susceptibilities resulting from vaccine failure can help achieve the goal of elimination of indigenous measles from the United States by 1996.
麻疹是一种传染性很强的病毒性疾病，曾感染过美国95%以上的人口。自从安全有效的疫苗获得许可以来，麻疹发病率已降至接种疫苗前水平的1%以下。然而，1989年至1991年期间麻疹的相对复发，使人们关注到维持高免疫水平的必要性，尤其是在城市地区的学龄前儿童中。提高疫苗接种覆盖率以及采用第二剂次接种策略以消除因疫苗失效导致的易感性，有助于实现到1996年在美国消除本土麻疹的目标。
