在宣布COVID-19大流行后，许多国家对公众集会实施限制，卫生工作者被重新用于COVID-19应对，公众对预防性卫生服务的需求因担心在医疗机构感染COVID-19而下降。这些因素导致在大流行的头几个月里，包括儿童免疫接种在内的保健服务中断。作为实现消除麻疹战略的一部分，在非洲区域开展了麻疹监测，并得到实验室确认。世界卫生组织制定了指导方针，以协助各国在大流行期间继续安全地提供基本卫生服务，包括免疫接种和监测疫苗可预防的疾病。我们分析了2014年至2020年麻疹病例监测和实验室数据库，以确定COVID-19大流行对麻疹监测的影响，并将2020年的表现与前几年进行比较。从2020年4月开始，每周报告的疑似麻疹病例有所下降。与2014-2018年的平均值相比，12个国家在2020年报告的病例数量和采集的样本数量下降超过50%。2020年，仅有30%的麻疹疑似病例标本在采集后3天内送达国家实验室。在区域层面，86%的地区在2020年报告了疑似麻疹病例，而非麻疹发热性皮疹发病率为每10万人2.1例，这是自2014年以来记录的最低发病率。只有11个国家在2020年实现了两个主要监测绩效指标的目标，而2014-2019年平均为21个国家。在COVID大流行期间，许多国家麻疹监测的总体质量有所下降。各国应立即采取积极主动的措施，重振麻疹的积极监测，并监测监测质量。我们建议各国考虑实施标本采集和检测方法，以便在偏远社区和交通困难地区及时确认疑似麻疹病例。
following the declaration of the COVID-19 pandemic, many countries imposed restrictions on public gatherings, health workers were repurposed for COVID-19 response, and public demand for preventive health services declined due to fear of getting COVID-19 in health care settings. These factors led to the disruption in health service delivery, including childhood immunization, in the first months of the pandemic. Measles surveillance supported with laboratory confirmation, is implemented in the African Region as part of the strategies towards attaining measles elimination. World Health Organisation developed guidelines to assist countries to continue to safely provide essential health services including immunization and the surveillance of vaccine preventable diseases during the pandemic. we analysed the measles case-based surveillance and laboratory databases for the years 2014 to 2020, to determine the impact of the COVID-19 pandemic on measles surveillance, comparing the performance in 2020 against the preceding years. the weekly reporting of suspected measles cases declined starting in April 2020. Twelve countries had more than 50% decline in both the number of reported cases as well as in the number of specimens collected in 2020, as compared to the mean for the years 2014-2018. In 2020, only 30% of the specimens from suspected measles cases arrived at the national laboratory within 3 days of collection. At Regional level, 86% of the districts reported suspected measles cases in 2020, while the non-measles febrile rash illness rate was 2.1 per 100,000 population, which was the lowest rate documented since 2014. Only 11 countries met the targets for the two principal surveillance performance indicators in 2020 as compared to an average of 21 countries in the years 2014-2019. the overall quality of measles surveillance has declined during the COVID pandemic in many countries. Countries should implement immediate and proactive measures to revitalise active surveillance for measles and monitor the quality of surveillance. We recommend that countries consider implementing specimen collection and testing methods that can facilitate timely confirmation of suspected measles cases in remote communities and areas with transportation challenges.
