Q & A on Legionella (Legionnaires’ disease)

A dangerous bacteria called Legionella pneumophila is becoming more and more prevalent in public settings such as hospitals and nursing homes. We’ve created this useful Q & A on Legionella to help break down what you need to know to stay safe.

What is Legionella?

Legionnaires’ disease was discovered in 1976, when a deadly outbreak struck attendants of an American Legion convention in Philadelphia. It is a severe, and at times lethal, form of pneumonia caused by Legionella bacteria.

How is it contracted?

The disease can be contracted by breathing in small droplets of water in the air that contain the Legionella pneumophila bacterium.

Where can it be found?

Q & A on Legionella 4

 

Legionella bacteria can be found naturally in freshwater environments but can become a public health hazard when it grows inside the water systems of man-made buildings. They can be found in:

  • Cooling towers in air conditioning systems
  • Hot tubs & whirlpools not drained between uses
  • Shower heads, sink faucets, and stagnant plumbing
  • Water systems in hotels, hospitals and nursing homes
  • Ice Machines
  • CPAP machines
  • Grocery store mist machines
  • Decorative fountains

How common is it?

The number of Legionella cases has been on the rise since 2000. In 2016, they were around 6,100 cases of Legionnaires’ disease reported in the United States.

What are the symptoms?

Who is most at risk?

Q & A on Legionella 2

Adults over the age of 50, former and current smokers, and people with weakened immune systems are especially at risk when exposed to Legionella.

What’s being done about it?

The Center for Medicare and Medicaid Services (CMS) recently issued a requirement for all healthcare organizations to start water management plans that reduce the risk of Legionnella growth inside their buildings. Part of these plans include routine testing of their water systems by a state-certified testing laboratory.
