The aim of this study was to describe an outbreak of pneumonia due to L. pneumophila in Llutxent (Valencia) and to know the evolution of these patients 10 years after.
The definition and identification of cases was carried out with the use of IFI techniques. An environmental and epidemiological study was performed for determining the origin and route of disease dissemination. The patients were clinically, functionally and serologically reviewed 10 years after.
From July to August 1983, 35 cases of pneumonia were reported in Llutxent (rate = 1.5%). L. pneumophila serotype 1 was serologically identified and was also found in shower heads and toilet tanks (in the context of the entry of sand into the drinking water supply). Ten years after, the patients had no respiratory symptoms with titers of antibodies versus Legionella sp. being under 1/64.
The authors emphasize the involvement of the distribution system for drinking water to the population in this first outbreak of Legionnaires disease in an open community. The health care measures taken were effective as demonstrated by no further pneumonias being recorded and after normalization of the rate of antibodies on a 10 year review.
本研究旨在描述卢克森特（巴伦西亚）因嗜肺军团菌引发的肺炎疫情，并了解这些患者10年后的病情发展。
采用免疫荧光技术进行病例的定义和鉴定。开展了一项环境与流行病学研究，以确定疾病传播的源头和途径。10年后对患者进行了临床、功能和血清学复查。
1983年7月至8月，卢克森特报告了35例肺炎病例（发病率=1.5%）。血清学鉴定出嗜肺军团菌1型，在淋浴喷头和马桶水箱中也发现了该菌（当时有沙子进入饮用水供应系统）。10年后，患者无呼吸道症状，针对嗜肺军团菌属的抗体滴度低于1/64。
作者强调了在这个开放社区首次爆发军团病时，饮用水分配系统对人群的影响。所采取的医疗保健措施是有效的，这体现在没有再记录到肺炎病例，且在10年复查时抗体水平恢复正常。
