ASHRAE Publishes Updated Legionellosis Standard

The CDC estimates there are between 8,000 and 18,000 cases of Legionnaires’ disease in the United States each year – and more than 10 percent of these cases are fatal. Legionella can also cause a less-severe influenza-like illness known as Pontiac Fever. Most of those cases are the result of exposure to Legionella found in building water systems.
