The annual number of confirmed cases of Legionnaires' disease in both Nottingham, and England and Wales, reached a peak in 1980 and has since declined. Legionella infection is a rare cause of community-acquired pneumonia managed at home (accounting for less than 1% of cases), more common in those admitted to hospital (5-15%) and more common still in patients with severe pneumonia as seen on an intensive care unit (up to 30% of cases). Antibiotic therapy for any patient with moderate or severe pneumonia of uncertain aetiology should cover legionella infection.
诺丁汉以及英格兰和威尔士每年确诊的军团病病例数在1980年达到峰值，此后呈下降趋势。军团菌感染是在家中治疗的社区获得性肺炎的罕见病因（占病例不到1%），在住院患者中更常见（5%-15%），在重症监护病房所见的重症肺炎患者中更为常见（高达病例的30%）。对于任何病因不明的中度或重度肺炎患者，抗生素治疗都应覆盖军团菌感染。
