The bacterium Legionella pneumophila and related bacteria are common in natural water sources such as rivers, lakes and reservoirs, but usually in low numbers. They may also be found in purpose-built water systems such as cooling towers, evaporative condensers, hot and cold water systems and spa pools.

Is Legionnaires highly contagious?

In general, people do not spread Legionnaires' disease and Pontiac fever to other people. However, this may be possible under rare circumstances. Your local health department can determine whether to investigate.

How can I prevent Legionella in my home?

Most people with Legionnaires' disease need care in a hospital, but will fully recover with treatment. However, about one in 10 who get this disease will die due to complications from their illness. Legionnaires' disease is caused by bacteria called Legionella that live in water.

How contagious is Legionnaires disease?

Legionellosis is not contagious, meaning it is not spread from person-to-person. Disease transmission primarily occurs through inhaling Legionella-contaminated, aerosolized water. While rare, exposure is also possible from breathing in (i.e., aspirating) Legionella contaminated soil or while drinking water.

Can you develop immunity to Legionella?

We have data on the largest collection of patients with LD in the world and have followed them for many years. Somewhat to our surprise, virtually none of them have become reinfected. Apparently, they developed immunity with their first infection.

What poses a low risk of exposure to Legionella?

A typical 'low risk' example may be found in a small building (eg housing unit) with small domestic-type water systems, where daily water usage is inevitable and sufficient to turn over the entire system; where cold water is directly from a wholesome mains supply (no stored water tanks); where hot water is fed from ...

Does all water have Legionella?

Legionella, the bacterium that causes Legionnaires' disease, occurs naturally in freshwater environments, like lakes and streams. Generally the low amounts of these bacteria in freshwater do not lead to disease. However, Legionella can pose a health risk when it gets into building water systems.

How rare is Legionnaires disease?

What temperature kills Legionella?

Notes. Hot water should be stored at 60 °C at least in order to kill legionella bacteria. The thermometer pocket at the top of the cylinder and on the return leg, if fitted, is a useful point for accurate temperature measurement. If installed, these measurements could be carried out by a building management system .

How long does it take for Legionella to develop in water?

Bacteria when in ideal conditions will grow, if you put legionella on an agar plate and incubate it for 7 - 10 days with a temperature range of between 20˚C and 50˚C, a colony will form of millions of bacteria that you will be able to see.
