Legionnaires' disease and Pontiac fever are both diseases with important public health implications and require prompt and thorough responses to outbreaks for future prevention. Effective methods for defining, diagnosing, reporting and responding to legionellosis outbreaks ideally should be standardized across countries. Therefore, the European Union surveillance methods for countering Legionnaires' disease is a useful model especially for travel-associated Legionnaires' disease (TALD) cases which are on the rise. Multi-country surveillance in the EU and European Economic Area (EEA) has evolved since the first organizational efforts in the 1980's to the currently responsible, European Legionnaires' Disease Surveillance Network (ELDSNet). This chapter outlines the practices of the EU surveillance of Legionnaires' disease including their schemata, definitions, responsibilities of participating members, methods and the results of the data collected since the program's inception. Lastly, improvements must still be made as the incidence of Legionnaires' disease in the EU is likely underestimated due to underreporting and/or underdiagnosis. Nearly 70% of cases are reported from only four countries, France, Germany, Italy and Spain, which represent 50% of the EU population.

欧洲军团病监测。

退伍军人病和庞蒂亚克热都是具有重要公共卫生影响的疾病，需要对暴发作出迅速和彻底的反应，以备将来预防。理想情况下，定义、诊断、报告和应对军团病暴发的有效方法应在各国标准化。因此，欧盟用于对抗军团病的监测方法是一个有用的模型，特别是对于呈上升趋势的与旅行相关的军团病 (TALD) 病例。欧盟和欧洲经济区 (EEA) 的多国监测自 1980 年代第一次组织努力发展为目前负责的欧洲退伍军人疾病监测网络 (ELDSNet)。本章概述了欧盟监视退伍军人的做法 疾病，包括他们的模式、定义、参与成员的责任、方法和自计划开始以来收集的数据的结果。最后，由于报告不足和/或诊断不足，欧盟退伍军人病的发病率可能被低估，因此仍必须做出改进。仅法国、德国、意大利和西班牙这四个国家报告了近 70% 的病例，这些国家占欧盟人口的 50%。
