Is legionellosis contagious?
Transmission. Legionellosis infection is transmitted when a person breathes water droplets from the air (i.e., mist or vapor) that contain the Legionella bacteria. The bacteria are not spread from person-to-person.
What kills Legionella?
Legionella needs a certain set of conditions to be able to survive. It needs to live in a temperature range of between 20 and 50˚C, above 50˚C it will start to die off. Heat will kill legionella bacteria, cold will not. If you have water below 20˚C it will go into hibernation, it will not die.
Where do most cases of Legionnaires occur?
Worldwide, waterborne Legionella pneumophila is the most common cause of cases including outbreaks. Legionella pneumophila and related species are commonly found in lakes, rivers, creeks, hot springs and other bodies of water.
Is there a vaccine for Legionnaires disease?
There are no vaccines that can prevent Legionnaires’ disease. Instead, the key to preventing Legionnaires’ disease is to reduce the risk of Legionella growth and spread. Building owners and managers can do this by maintaining building water systems and implementing controls for Legionella.
Can you get Legionnaires disease from a humidifier?
Legionella is transmitted in aerosols which have to be drawn deep into a person’s respiratory system. Any humidifier that produces an aerosol such as an atomising humidifier or ultrasonic mister, particularly if they spray directly in the air where people are present, is therefore a potential source of concern.
What happens if you drink water with Legionella?
