Three cases of Legionnaires' in Sydney
Three men have been diagnosed with Legionnaires' disease in Sydney's northwest, sending the health department searching for a contamination source in the area.
All three patients developed the type of Legionnaires' disease that develops after a person breathes in contaminated water droplets, NSW Health said in a statement on Tuesday.
The Hills Shire Council and public health units in the area have started precautionary inspections of cooling towers, as outbreaks can be associated with contaminated air conditioning systems.
The bacterial infection can not be spread from person to person.
