The group outbreak of Legionnaire’s Disease in the Lisbon suburbs in 2014 has provided a sad reminder: the propagation of legionellae within the water circuits of cooling towers is a likely scenario and one capable of causing major health impacts whenever water droplets are dispersed from these towers. The regulatory regime for preventing the risk of legionellae stemming from cooling towers has been substantially modified. The regulations currently in effect in France are considered by experts to be among the most elaborate. Nonetheless, new cases of Legionnaire’s Disease are still being recorded every year.
The objective of this flash is to present a few significant recent events in France and other countries and to highlight prevention measures based on the analysis of these group outbreaks of Legionnaire’s disease.
