New outbreak of legionellosis in Sevilla, Spain

One of the three cases of legionellosis reported in Osuna has died. Authorities have closed a sprinkler system and two cooling towers in Osuna (Sevilla) as a preventive measure until a full investigation can determine the source of these infections. Transmission of legionellosis (Legionnaires Disease) usually occurs following exposure to warm aerosolized 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 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.
