7 p.m. daily. The patient was one of five originally diagnosed with the disease at the hospital in Havre de Grace. Doctors declined to identify the patient, citing confidentiality. They say the patient was admitted to the hospital with pneumonia on June 28th, 1999. No new cases of the disease have been reported.
Officials believe a hot water tank at the hospital was the probable source of the bacteria.
The water system was flushed with super heated water to kill any remaining bacteria. The tank has been taken off line. About a dozen water samples taken from the tank and outlets downstream from it tested positive for the bacteria. The water supply for the hospital did not test positive, although small amounts of the bacteria are believed to have entered the hospital through the water supply and multiplied in the warmth of the tank. The system was tested July 2 and superheated July 3.
