What is Legionnaires’ disease? Legionnaires’ disease is a serious lung infection caused by Legionella bacteria. Initial symptoms usually include flu-like symptoms, such as: mild headaches muscle pain high temperature (fever), usually 38C (100.4F) or above chills tiredness changes to your mental state, such as confusion Once bacteria begin to infect your lungs, you may also experience symptoms of pneumonia, such as: a persistent cough – which is usually dry at first, but as the infection develops you may start coughing up phlegm or, rarely, blood shortness of breath chest pains It usually takes six to seven days between getting the infection and the start of symptoms (known as the incubation period), although it can be any time from two to 19 days. Legionnaires’ disease is caused by Legionella bacteria infecting your lungs. It's usually caught by breathing in small droplets of contaminated water. The infection isn't contagious and can't be spread directly from person to person. Legionella bacteria is usually found (often in harmlessly low numbers) in sources of water, such as ponds, rivers and lakes. However, the bacteria can rapidly multiply if they find their way into artificial water supply systems, such as air conditioning systems. Large buildings, such as hotels, hospitals, museums and office blocks, are more vulnerable to Legionella contamination because they have larger, more complex water supply systems in which the bacteria can quickly spread. The two things that Legionella bacteria need to grow and reproduce are: a water temperature of 20-45 o C (68-113F) impurities in the water that the bacteria can use for food – such as rust, algae and limescale Although rare, Legionnaires' disease has also come from contaminated showers, sprinkler systems and spas. Everyone is potentially at risk of developing Legionnaires’ disease. However, certain things make it more likely that you will experience a more severe form of the infection. These include: being 50 years of age or over – 235 (83%) of the 284 confirmed cases in 2013 involved people over 50 years of age smoking, or having smoked heavily in the past (a recent study has shown that smoking cannabis may also increase your risk) drinking alcohol heavily about three-quarters have an underlying medical condition, such as diabetes, kidney disease, or a pre-existing lung condition having a weakened immune system – for example, people with HIV and AIDS or cancer The best way to prevent an outbreak of Legionnaires’ disease is to ensure that any water system under your control is properly maintained and conforms to relevant health and safety regulations. This mainly involves keeping water either cooled below 20 o C or heated above 60 o C. The water supply should also be kept free of impurities and moving, so that it doesn't stagnate. The Health and Safety Executive (HSE) is an independent regulator for reducing work-related death and serious injury in Britain. It provides guidance about Legionnaires' disease on its website, including information and advice about managing Legionella in hot and cold water systems.
