Secondary prevention

Respiratory hygiene measures, such as the use of hand hygiene and tissues for patients who cough are recommended to reduce the risk of spread.

Epidemiological investigation is generally warranted (either by the local infection control team or by official epidemiological investigation) in cases where Legionella pneumophila infection has been diagnosed to prevent further exposure and infections,[29][100][101] and to improve water Legionella disinfection measures.[102]
