Key facts

The bacterium L. pneumophila was first identified in 1977, as the cause of an outbreak of severe pneumonia in a convention centre in the USA in 1976.
The most common form of transmission of Legionella is inhalation of contaminated aerosols produced in conjunction with water sprays, jets or mists. Infection can also occur by aspiration of contaminated water or ice, particularly in susceptible hospital patients.
Legionnaires’ disease has an incubation period of 2 to 10 days (but up to 16 days has been recorded in some outbreaks).
Death occurs through progressive pneumonia with respiratory failure and/or shock and multi-organ failure.
Untreated Legionnaires’ disease usually worsens during the first week.
Of the reported cases 75–80% are over 50 years and 60–70% are male.
