Grady awaits tests in disease probe

Atlanta-based Grady Memorial Hospital itself is the most likely source of the Legionnaires' disease that has sickened four patients since Jan. 1, but results from water tests inside the hospital will not be ready until February 9. All four patients are responding well to antibiotics, hospital spokeswoman Denise Simpson said. Susan Lance, MD, a Georgia epidemiologist, said the patients diagnosed with Legionnaires' disease appear to have no ties other than their treatment at Grady. State and federal public health officials are helping Grady Memorial Hospital track down the source of the bacteria.
