More Legionnaires Disease cases reported in Renfrew, Scotland

Since the initial report of the outbreak of Legionnaires Disease in Renfrew, Scotland, in mid-July, there have been 4 more cases, bringing the total to 10. Local air conditioning water towers were treated in July to decontaminate any towers that might have been harbouring this infectious agent. The new cases may simply represent people who were somehow exposed before the towers were treated, or they may be new exposures. The exact source of these infections has not been identified as yet.

Transmission of legionellosis (Legionnaires Disease) usually occurs following exposure to warm water aerosols since the bacteria are inhaled through water droplets in water sprays or mists. Exposure can occur in or around hot tubs, showers, or from air conditioning systems in buildings with poorly maintained cooling towers.Travellers who develop serious respiratory symptoms after being in air conditioned buildings or other environments that generate sprays in the outbreak area should seek medical care as soon as possible.
