Legionnaires' Disease is a pneumonia like illness caused by the Legionella bacteria and can be fatal. The infection is caused by breathing in small droplets of water contaminated by the bacteria. The disease cannot be passed from one person to another.
Legionella bacteria are found in the natural environment and may contaminate and grow in water systems, including domestic hot and cold water systems. They survive low temperatures and thrive at temperatures between 20 - 45°C if the conditions are right. They are killed by high temperatures at 60°C or above. Because the water in your house comes from the natural environment, Legionella bacteria will probably be in your water system too, however it takes about two weeks for the bacteria to multiply sufficiently to pose any real risk, and then you have to breathe it in for it to pose any risk at all.
Don't panic. If you use your water system regularly, then there is virtually no risk. In fact, the Health & Safety Executive thinks that the risk is virtually nothing especially if you have a combi boiler fitted. But, to ensure that you are safe and to give you piece of mind you can apply our TIDY little memory aid.
