Legionnaires' disease is an uncommon form of pneumonia caused by a type of bacterium that is found in the environment. It causes disease when it is spread through the air as a spray or vapour from a water source and droplets are inhaled. It cannot be spread from one person to another.

The symptoms of Legionnaires' disease include a 'flu-like' illness with muscle aches, tiredness, headaches, dry cough and fever, leading on to pneumonia. Sometimes diarrhoea occurs and patients may suffer from confusion.

People who experience such symptoms should seek medical attention promptly, so that appropriate and effective antibiotic treatment can be given. People feeling unwell who have stayed at the Hotel are encouraged to visit their local health provider and seek prompt and effective treatment.

Notes to Editors:

1. Legionnaires' disease is pneumonia, caused by the bacterium Legionella pneumophila. The majority of cases are reported as single (isolated) cases but outbreaks can occur. Some 5000 cases are reported annually across the EU and EEA/EFTA countries. All ages can be affected, but it mainly affects people over 50 years of age, and generally men more than women and more often, smokers.

2. The incubation period ranges from 2 to 14 days. In rare cases some people may develop symptoms as late as three weeks after exposure. It cannot be passed from person to person. Outbreaks may have a source of infection in common but most cases are 'sporadic' i.e. with no links to a common source or strain of the Legionella bacteria.

3. The symptoms of Legionnaires' disease include a 'flu-like' illness with muscle aches, tiredness, headaches, dry cough and fever, leading on to pneumonia. Sometimes diarrhoea occurs and patients may suffer from confusion. It can be treated with antibiotics. People should be advised to seek medical attention if they have a respiratory illness suggestive of Legionnaires' disease.

4. Legionella bacteria are widely distributed in the environment. Systems linked to outbreaks have included: cooling towers; evaporative condensers; hot and cold water systems; spa pools; humidifiers in food display cabinets; effluent treatment plants; air scrubbers.
