Legionellosis outbreak in UK, source unknown at present

An investigation is underway to determine the source of Legionnaires Disease reported in 7 people in Stoke-on-Trent. All 7 patients were being treated at the University Hospital of North Staffordshire.

Transmission of legionellosis usually occurs following exposure to warm aerosolised water as 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 cooling towers. Travellers who develop serious respiratory symptoms after being in air conditioned buildings should seek medical care as soon as possible. Until a common source for these cases is identified, travellers should follow local reports and recommendations to avoid possible exposure.
