What is Legionnaires' disease?

Legionnaires’ disease is a form of pneumonia, fatal in approximately 12% of cases. The bacterium Legionellapneumophila serogroup 1 is the most common cause of Legionnaires’ disease. It first hit the headlines in 1976 after an outbreak among attendees at an American Legion Convention in Philadelphia, where 221 people were infected, of which 34 died.

Legionnaires’ disease primarily affects people who have increased susceptibility due to predisposing factors, such as age (50 years +), smoking, existing illnesses etc. Men are also three times more susceptible than women. Legionella bacteria infections can only be contracted by the deep inhalation of tiny water droplets, called aerosols, which are contaminated with legionella bacteria. Aerosols can be produced from water systems that create sprays, such as showers, cooling towers, spray taps, decorative fountains and Jacuzzis. Infection by person-to-person contact has not been reported.

Legionella bacteria can pose a real threat to your buildings and the people who work in them.
