Atlanta hospital isolates cause of Legionnaires'

Water tests confirmed that two units at Atlanta-based Grady Memorial Hospital were the source of the bacteria that caused Legionnaires' disease in four patients. "We're comfortable right now that it’s only the two units," Leon Haley, MD, deputy senior vice president of medical affairs at Grady, told the Atlanta Journal-Constitution. The two Grady patient units—and 80 beds—have been closed since last week. Grady officials said crews are hyper-chlorinating additional floors and will continue testing throughout the hospital.
