Via CBC News: 'Cluster' of cases of Legionnaires' disease confirmed in Surrey. Excerpt:
The Fraser Health Authority says it is investigating a "cluster" of cases of Legionnaires' disease in the Guildford area of Surrey.
The illness, caused by the Legionella bacteria, can lead to pneumonia in people who are at higher risk of getting sick.
The bacteria is commonly found in freshwater, groundwater and soil. It often grows and spreads in water systems like cooling towers, decorative fountains, plumbing systems and hot tubs that aren't cleaned properly.
People get Legionnaires' disease when they breathe in droplets of contaminated water.
In a release, Fraser Health said it is investigating the source of the bacteria. A spokesperson said there have been fewer than 10 cases reported.
Most healthy people don't get sick from the bacteria, but smokers, the elderly and those with pre-existing lung conditions or compromised immune systems are at higher risk.
