title: Legionnaires' disease outbreak at an Atlanta, Georgia, Country Club: evidence for spread from an evaporative condenser.
abstract: During July 1978 an outbreak of Legionnaires' disease characterized by high fever, prostration, and pneumonia occurred at an Atlanta, Georgia, country club. All eight cases involved club members whose primary club activity was golfing. The degree of golfing activity during the likely exposure period was a risk factor for acquiring the illness. Legionella pneumophila was isolated from the evaporative condenser within the clubhouse. The fact that the stream of air blowing from the exhaust duct of the evaporative condenser was directed toward a nearby practice green and the 10th and 16th tees supports the hypothesis that this outbreak represents airborne dissemination of L. pneumophila from the evaporative condenser to an outdoor site where susceptible golfers contracted the illness.
