More than 21 million participants attended EXPO Milan from May to October 2015, making it one of the largest protracted mass gathering events in Europe. Given the expected national and international population movement and health security issues associated with this event, Italy fully implemented, for the first time, an event-based surveillance (EBS) system focusing on naturally occurring infectious diseases and the monitoring of biological agents with potential for intentional release. The system started its pilot phase in March 2015 and was fully operational between April and November 2015. In order to set the specific objectives of the EBS system, and its complementary role to indicator-based surveillance, we defined a list of priority diseases and conditions. This list was designed on the basis of the probability and possible public health impact of infectious disease transmission, existing statutory surveillance systems in place, and any surveillance enhancements during the mass gathering event. This article reports the methodology used to design the EBS system for EXPO Milan and the results of 8 months of surveillance.
超过 2100 万名参与者参加了 2015 年 5 月至 10 月在米兰举办的 EXPO，这使其成为欧洲最大的长期大规模集会活动之一。考虑到此次活动预计会引发的国内外人口流动和卫生安全问题，意大利首次全面实施了一项以自然发生的传染病为重点、同时监测具有潜在蓄意释放风险的生物制剂的基于事件的监测（EBS）系统。该系统于 2015 年 3 月开始试行阶段，并于 2015 年 4 月至 11 月全面运行。为了确定 EBS 系统的具体目标及其对基于指标的监测的补充作用，我们定义了一系列优先疾病和情况。该清单是根据传染病传播的可能性和可能对公众健康造成的影响、现有的法定监测系统以及大规模集会期间的任何监测增强情况制定的。本文报告了为 EXPO 米兰设计 EBS 系统所采用的方法以及 8 个月监测的结果。
