2012年，世界卫生组织西太平洋区域委员会(WPR)重申了消除麻疹的承诺，并敦促WPR成员国尽快阻断麻疹病毒的传播。2013年，尽管实施了消除麻疹的战略，包括2011年使用含麻疹和风疹疫苗的全国补充免疫活动(SIA)，并以9个月至7岁的儿童为对象，但菲律宾仍爆发了大规模麻疹疫情。为了预防未来的麻疹暴发，根据以前在菲律宾应用的WPR脊髓灰质炎风险评估工具，开发了一种新的工具来评估麻疹暴发的地区一级风险。风险被评估为来自四个数据输入类别的综合指标分数的函数：人群免疫力、监测质量、计划执行情况和威胁评估。在总体得分的基础上，该工具为每个地区分配了低、中、高或极高的风险类别。在菲律宾的122个区和高度城市化的城市中，58个(48%)被归类为高风险或极高风险，包括2013年疫情开始爆发的马尼拉大都会地区和4A区。在2014年进行的全国SIA期间，风险评估结果被用于指导监测和监督。在菲律宾起草的最初工具作为开发全球风险评估工具的模板。每年定期进行麻疹方案风险评估可用来帮助规划风险缓解活动和衡量消除麻疹的进展情况。
In 2012, the World Health Organization Regional Committee for the Western Pacific Region (WPR) reaffirmed its commitment to eliminate measles and urged WPR member states to interrupt endemic measles virus transmission as rapidly as possible. In 2013, a large measles outbreak occurred in the Philippines despite implementation of measles elimination strategies including a nationwide supplemental immunization activity (SIA) in 2011 using measles- and rubella-containing vaccine and targeting children aged nine months to seven years. To prevent future measles outbreaks a new tool was developed to assess district-level risk for measles outbreaks, based on the WPR polio risk assessment tool previously applied in the Philippines. Risk was assessed as a function of combined indicator scores from four data input categories: population immunity, surveillance quality, program performance, and threat assessment. On the basis of the overall score, the tool assigned each district a risk category of low, medium, high, or very high. Of the 122 districts and highly urbanized cities in the Philippines, 58 (48%) were classified as high risk or very high risk, including the district of the Metro Manila area and Region 4A where the outbreak began in 2013. Risk assessment results were used to guide the monitoring and supervision during the nationwide SIA conducted in 2014. The initial tool drafted in the Philippines served as a template for development of the global risk assessment tool. Regular annual measles programmatic risk assessments can be used to help plan risk mitigation activities and measure progress toward measles elimination.
