1978年至1982年间，弗吉尼亚大学医院的肾移植患者中发生了一场医院感染性军团菌肺炎的流行。尽管1982年后没有进一步的病例被诊断出来，但由于担心医院水中的微生物L的持久性，1985年安装了过滤器和紫外线（UVL）配件，试图对输送到移植患者房间的水进行消毒。从8个紫外线处理室和8个控制室获得水样。95份对照样品中有26份为微生物立克次体培养阳性，而71份经紫外线处理的过滤水样品中无1份为阳性（p <0.0001，Fisher精确检验）。在UVL接头和过滤器因泄漏而被旁路后，来自UVL室的33个样品中有9个呈阳性（p<0.0001）。这些数据表明，紫外线治疗可能是有用的持续消毒的水在医院的高风险患者的房间。
An epidemic of nosocomialLegionella micdadeipneumonia occurred among renal transplant patients in the University of Virginia hospital between 1978 and 1982. Although no further cases were diagnosed after 1982, filters and ultraviolet light (UVL) fittings were installed in 1985 as an attempt to disinfect water piped to rooms of transplant patients, because of concern about persistence ofL micdadeiin hospital water. Water samples were obtained from eight UVL-treated rooms and eight control rooms. 26 of 95 control samples were culture positive forL micdadeicompared with 0 of 71 samples of filtered, UVL-treated water (p <0·0001, Fisher's exact test). After the UVL fitting and filter had been bypassed because of a leak, 9 of 33 samples from the UVL rooms were positive (p<0·0001). These data suggest that UVL treatment may be useful in continuous disinfection of water in the hospital rooms of high-risk patients.
