Legionella Risk Assessment

Legionnaire’s disease is most commonly caused by the inhalation of water droplets contaminated with the legionella bacteria. It is therefore important that systems susceptible to colonisation by legionella bacteria and which incorporate a potential means for creating and disseminating water droplets should be identified and the risk they present should be assessed. The legionella risk assessment takes account of:

The potential for formation of water droplets
The condition of the water
The water temperature
The water turnover rate
The susceptibility of persons exposed to any water droplets
The population density exposed to any water droplets

Statistics

The fatality rate of Legionnaires' disease has ranged from 5% to 30% during various outbreaks

Most legionnaires' infections occur in those who are middle-age or older

A recent research study provided evidence that Legionella pneumophila, the causative agent of Legionnaires' disease, can travel airborne at least 6 km from its source

Between 1995 and 2005 over 32,000 cases of Legionnaires' disease and more than 600 outbreaks were reported to the European Working Group for Legionella Infections (EWGLI)
