In 2001, the countries of the World Health Organization (WHO) African Region (AFR) became part of a global initiative with a goal of reducing the number of measles deaths by 50% by 2005, compared with 1999. Recommended strategies for measles mortality reduction included 1) increasing routine coverage for the first dose of measles-containing vaccine (MCV1) for all children, 2) providing a second opportunity for measles vaccination through supplemental immunization activities (SIAs), 3) improving measles case management, and 4) establishing case-based surveillance with laboratory confirmation of all suspected measles cases. Before introduction of MCV throughout AFR, approximately 1 million measles cases had been reported each year in the early 1980s. After strengthening measles-control activities, annual reported cases declined to an estimated 300,000- -580,000 during the 1990s. This report summarizes the progress made during 2001- -2008 toward improving measles control in AFR. During 2001- -2008 estimated MCV1 coverage increased from 57% to 73%, SIAs vaccinated approximately 398 million children, and reported measles cases decreased by 93%, from 492,116 in 2001 to 32,278 in 2008. By 2005, global measles deaths had decreased by 60%, and the AFR goal had been achieved; AFR adopted a new goal to reduce deaths by 90%, compared with 2000, and that goal was achieved in 2006. However, inaccuracies in reported vaccination coverage exist, surveillance is suboptimal, and measles outbreaks continue to occur in AFR countries. Further progress in measles control will require full implementation of recommended strategies, including validation of vaccination coverage.
2001年,世界卫生组织(WHO)非洲区域(AFR)的国家成为一项全球倡议的一部分,该倡议的目标是到2005年将麻疹死亡人数比1999年减少50%。推荐的降低麻疹死亡率的策略包括:1)提高所有儿童首剂含麻疹疫苗(MCV1)的常规接种覆盖率;2)通过补充免疫活动(SIA)提供第二次麻疹疫苗接种机会;3)改善麻疹病例管理;4)建立基于病例的监测系统,并对所有疑似麻疹病例进行实验室确诊。在整个非洲区域引入MCV之前,20世纪80年代初每年报告的麻疹病例约为100万例。加强麻疹控制活动后,20世纪90年代每年报告的病例数降至约30万至58万例。本报告总结了2001年至2008年期间非洲区域在改善麻疹控制方面取得的进展。在200年至2008年期间,估计MCV1接种覆盖率从57%提高到73%,SIA为约3.98亿儿童接种了疫苗,报告的麻疹病例减少了93%,从2001年的492,116例降至2008年的32,278例。到2005年,全球麻疹死亡人数减少了60%,非洲区域的目标得以实现;非洲区域采用了一个新目标,即到2006年将死亡人数比2000年减少90%,该目标也得以实现。然而,报告的疫苗接种覆盖率存在不准确之处,监测效果欠佳,非洲区域国家仍不断有麻疹疫情发生。要在麻疹控制方面取得进一步进展,需要全面实施推荐的策略,包括核实疫苗接种覆盖率。
