Abstract：
We determined whether the incidence rates of travel-associated Legionnaires\' disease (TALD) in hotels in Germany increased after a previous occurrence and whether control measures required by the European Legionnaires\' Disease Surveillance Network after a cluster (>2 cases within 2 years) restored the rate to baseline. We analyzed TALD surveillance data from Germany during 2015-2019; a total of 307 TALD cases (163 domestic, 144 nondomestic) in hotels were reported. The incidence rate ratio was 5.5 (95% CI 3.6-7.9) for a second case and 25 (95% CI 11-50) for a third case after a cluster had occurred, suggesting that control measures initiated after the occurrence of TALD clusters might be inadequate to restore the incidence rate to baseline. Our findings indicate that substantial LD preventive measures should be explored by hotels or other accommodations after the first TALD case occurs to reduce the risk for future infections.
摘要：
我们确定了德国酒店中旅行相关军团病（TALD）的发病率在以前发生后是否增加，以及欧洲军团病监测网络要求的控制措施在集群（2年内>2例）后是否将发病率恢复到基线。我们分析了2015-2019年德国的TALD监测数据；共有307例TALD病例(163例国内，据报道，酒店中有144家非国内）。发生集群后，第二例的发生率为5.5（95％CI3.6-7.9），第三例为25（95％CI11-50）。提示在TALD集群发生后开始的控制措施可能不足以将发病率恢复到基线水平.我们的发现表明，在第一例TALD病例发生后，酒店或其他住宿场所应探索大量的LD预防措施，以降低未来感染的风险。
