尽管为控制麻疹作出了重大努力，但麻疹仍是莫桑比克的一个主要公共卫生问题。目前，卫生当局将疫情控制建立在常规监测系统的数据基础上，而疫苗覆盖率和效力则是根据目标人口的数学预测来计算的。这项工作的目的是在马普托市(1998年)和马尼卡省(2002年)两次暴发期间评估麻疹报告系统的质量。回溯性地，我们从常规监测系统收集数据，即卫生机构的登记簿和每周的省和国家流行病学报告。为了测试各省是否登记了疫情，将麻疹病例的分布与根据前几年报告的病例确定的流行水平进行了比较。从卫生机构向省和国家一级通报麻疹病例的情况严重不足。作为麻疹监测系统的主要信息来源，登记簿被发现有两个主要变量不完整：“年龄”和“疫苗接种状况”。莫桑比克的监测系统以质量较差的记录为基础，只收到该国麻疹总数的一小部分的通知，可能导致无法检测到流行病。麻疹报告系统不提供扩大免疫规划管理者做出循证决策所需的数据，也不允许进行深入分析以监测该国的麻疹流行病学。莫桑比克在下一阶段消除麻疹方面的进展将需要改进常规监测系统和更强大的卫生信息系统。
Measles remains a major public health problem in Mozambique despite significant efforts to control the disease. Currently, health authorities base their outbreak control on data from the routine surveillance system while vaccine coverage and efficacy are calculated based on mathematical projections of the target population. The aim of this work was to assess the quality of the measles reporting system during two outbreaks that occurred in Maputo City (1998) and in Manica Province (2002). Retrospectively, we collected data from the routine surveillance system, i.e. register books at health facilities and weekly provincial and national epidemiological reports. To test whether the provinces registered an outbreak, the distribution of measles cases was compared to an endemic level established based on cases reported in previous years. There was a significant under-notification of measles cases from the health facilities to the province and national level. Register books, the primary sources of information for the measles surveillance system, were found to be incomplete for two main variables: "age" and "vaccination status". The Mozambican surveillance system is based on poor quality records, receives the notification of only a fraction of the total number of measles in the country and may result in failures do detect epidemics. The measles reporting system does not provide the data needed by Expanded Program on Immunisation managers to make evidence-based decisions, nor does it allow in-depth analysis to monitor measles epidemiology in the country. The progress of Mozambique to the next stage of measles elimination will require an improvement of the routine surveillance system and a stronger Health Information System.
