Legionnaires' disease is underreported in Europe; notification rates differ substantially among countries. Approximately 20% of reported cases are travel-associated. To assess the risk for travel-associated Legionnaires' disease (TALD) associated with travel patterns in European countries, we retrieved TALD surveillance data for 2009 from the European Surveillance System, and tourism denominator data from the Statistical Office of the European Union. Risk (number cases reported/number nights spent) was calculated by travel country. In 2009, the network reported 607 cases among European travelers, possibly associated with 825 accommodation sites in European Union countries. The overall risk associated with travel abroad was 0.3 cases/million nights. We observed an increasing trend in risk from northwestern to southeastern Europe; Greece had the highest risk (1.7). Our findings underscore the need for countries with high TALD risks to improve prevention and control of legionellosis; and for countries with high TALD risks, but low notification rates of Legionnaires' disease to improve diagnostics and reporting.
欧洲的军团病报告不足; 各国的报告率差异很大。大约 20%的报告病例与旅行有关。为了评估与欧洲国家旅行模式相关的旅行相关军团病（TALD）的风险，我们从欧洲监测系统检索了 2009 年的 TALD 监测数据，并从欧盟统计局检索了旅游分母数据。风险（报告的病例数/过夜数）按旅行国家计算。2009 年，该网络报告了 607 例欧洲旅行者感染军团病，可能与欧盟国家的 825 个住宿点有关。与出国旅行相关的总体风险为每百万夜 0.3 例。我们观察到风险从西北到东南欧洲呈上升趋势; 希腊的风险最高（1.7）。我们的研究结果强调了高 TALD 风险国家需要加强军团病的预防和控制; 对于高 TALD 风险但军团病报告率低的国家，需要改善诊断和报告。
