What are the first signs of Legionnaires disease?

What is the danger zone for Legionella?

Legionella bacteria is commonly found in water. The bacteria multiply where temperatures are between 20-45°C and nutrients are available. The bacteria are dormant below 20°C and do not survive above 60°C.

What time of year is Legionnaires disease most likely?

A recent study estimated that the true number of Legionnaires' disease cases may be 1.8–2.7 times higher than what is reported. More illness is usually found in the summer and early fall, but it can happen any time of year.

Hydrosense test is the only Legionella test in the world that can be fully conducted on-site and does not require any in-depth training or experience. It works just like a pregnancy test- you put the water sample on a test and wait 25 minutes to receive the result.

How prevalent is Legionella in the US?

Around 6,000 Legionnaires' disease cases are reported each year in the United States.

What temperature kills Legionnaires disease?

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 .

What kills Legionnaires disease?

Chemical shock using an elevated level of a disinfectant, such as chlorine, for a limited duration can control Legionella in a potable water system.

Who is most at risk from Legionnaires disease?

Infections have been known to occur in people who work with large cooling towers or air conditioning systems. The people most at risk for contracting Legionnaires' disease are those with weakened immune systems, as they have little defense against the onset of infection.

People contract Legionnaires' disease by inhaling small droplets of water (aerosols), suspended in the air, containing the bacteria. Certain conditions increase the risk from legionella if: the water temperature in all or some parts of the system may be between 20-45 °C, which is suitable for growth.

How often should you check for Legionnaires?

It depends on the system that you have and the outcome of your risk assessment. For open systems, such as cooling towers, evaporative condensers and spa pools etc, routine testing should be carried out at least quarterly. However, there may be circumstances were more frequent sampling may be required.

Can you get Legionnaires from air conditioning?

Any air conditioning system installed and/or maintained by the team at Andrews Air Conditioning is not at risk of Legionella contamination. We specialise in systems that use an air-cooled refrigerant, which means that the requisite environment for the spread of bacteria is not present.
