Can air conditioning cause pneumonia?

The pneumonia ‘Legionnaire’s disease’ is caused by the bacterium Legionella pneumophila and is found in faulty air conditioning units of large buildings e.g. hospitals or hotels. The bacteria can survive in warm, moist, air conditioning units and if present can cause an outbreak of the disease.

How does a person get Legionnaires disease?

People can get Legionnaires’ disease or Pontiac fever when they breathe in small droplets of water in the air that contain the bacteria. Less commonly, people can get sick by aspiration of drinking water containing Legionella. This happens when water accidently goes into the lungs while drinking.

What is the test for Legionnaires disease?

The most commonly used laboratory test for diagnosis of Legionnaires’ disease is the urinary antigen test, which detects a molecule of the Legionella bacterium in urine. If the patient has pneumonia and the test is positive, then you should consider the patient to have Legionnaires’ disease.

Does Legionnaires disease go away by itself?

Various tests have confirmed that copper and silver ions can kill 99.9% of Legionella bacteria present in a system. NASA has used this form of disinfection to provide safe drinking water for those aboard Apollo space shuttles in the Sixties.

How do you kill Legionella bacteria in water?

A water temperature of 120°F does not kill the Legionella bacteria; a hot water temperature of 140°F is required at which Legionellae dies in 32 minutes. Hence it is recommended that the water heater be set at a safe hot water temperature of 140°F. The Legionella disinfection range is 158 – 176 °F.

What kills Legionella?

Heat will kill legionella bacteria, cold will not. If you have water below 20˚C it will go into hibernation, it will not die. Its optimum temperature for growth is 37˚C, body core temperature, which is why it makes such an efficient attack on the human body once it gets into our system.

What is the most common way of contracting Legionnaires disease?

Most people catch Legionnaires’ disease by inhaling the bacteria from water or soil. Older adults, smokers and people with weakened immune systems are particularly susceptible to Legionnaires’ disease.
