During the first half of March 1980, an unseasonal outbreak of legionellosis, which involved at least 14 of approximately 1,000 workers, occurred in a 6-month-old office building in San Francisco. An epidemiologic investigation revealed that persons 50 yr of age and older were at increased risk of disease. The outbreak was temporally associated with operation of the building's air conditioning system. In addition, Legionella pneumophila Serogroups 1, 4, and 6 were identified in water samples taken from a rooftop air conditioning cooling tower located directly across the street from an area of recent excavation.
1980年3月上半月，在旧金山一座建成6个月的办公楼里，发生了一起不合时令的军团病暴发，在约1000名工作人员中至少有14人患病。一项流行病学调查显示，50岁及以上的人患病风险增加。此次暴发在时间上与该建筑的空调系统运行有关。此外，在从紧邻最近一处挖掘区域街道对面的屋顶空调冷却塔采集的水样中，鉴定出了嗜肺军团菌血清型1、4和6 。
