– Legionnaires’ disease was unknown before 1976; in 1976 the first recognized cases of the disease occurred in Philadelphia at a Legionnaires’ convention at a hotel where 221 attendees contracted the disease and 34 of them died.
– Leginnaires’ disease lives in water including plumbing systems, cooling towers and air conditioning systems. It is transmitted by inhalation of water droplets contaminated with the Legionella bacteria.
– To prevent the disease we have to make sure “building water systems are properly inspected and kept clean…no city has made this requirement” so the pending NYC legislation is a positive step.
