The Origin of Legionnaires’ Disease
Legionnella was discovered following an outbreak in 1976 in a convention in Philadelphia, USA amongst Legionnaires who went to a convention of the American Legion.
A total of 130 of the delegates were hospitalised during or just after the conference with symptoms such as tiredness, chest pain, lung congestion and fever. 25 of those died.
Following an investigation, the legionella bacterium was identified and was found to be breeding in the cooling tower of the hotel’s air conditioning system which had then spread throughout the building.
Thankfully, since that time, preventative measures have been put into place, worldwide, to ensure something on this scale never happens again.
Legionella bacterium can also occur anywhere where there is water, such as
- Hot and cold water systems in schools, hospitals and care homes.
- Swimming pools in leisure clubs
- Old pipework and deadlegs
- Decorative fountains
How we can help:
We carry out legionella risk assessments to identify such problems and help eradicate them or put systems into place to ensure they don’t occur in the first place.
