Measles is a highly infectious, acute viral illness that can cause severe pneumonia, diarrhea, encephalitis, and death. To characterize the epidemiology of measles in the United States during 2001-2003, CDC analyzed data reported by state and local health departments. This report summarizes the results of that analysis, which indicated that no endemic measles virus is circulating in the United States; however, imported measles cases continue to occur and can result in limited indigenous transmission. Maintaining immunity through high vaccination coverage levels is essential to limit the spread of measles from imported cases and prevent measles from becoming endemic.
麻疹是一种具有高度传染性的急性病毒性疾病，可导致严重肺炎、腹泻、脑炎及死亡。为描述2001 - 2003年美国麻疹的流行病学特征，美国疾病控制与预防中心（CDC）分析了州和地方卫生部门报告的数据。本报告总结了该分析结果，结果表明美国境内无地方性麻疹病毒传播；然而，输入性麻疹病例仍有发生，并可导致有限的本土传播。通过高疫苗接种覆盖率维持免疫力对于限制输入性病例引发的麻疹传播以及防止麻疹成为地方性疾病至关重要。
