Under investigation is a recent spike in Legionnaires’ disease at Grady Memorial Hospital in Atlanta, Georgia. Four patients at the hospital have contracted Legionnaires’ disease within the past month. Several Hospital floors have been shut down to prevent additional illness. Hospital administrators are cooperating with State Health Department officials in order to determine the cause of the outbreak.

UPDATE: The source of the Legionalla at Grady Memorial Hospital was determined to be the water in two units. Those units, as well as additional floors, have been super-chlorinated in an effort to rid the building of the bacteria. The effort is ongoing.
