Pittsburgh hospital looks for mold source after three deaths

A Pittsburgh hospital is working to find and eradicate the source of a rare mold that may have contributed to the deaths of three transplant patients and left a fourth person in "guarded condition," a hospital spokeswoman said on Monday. Concern over mold at the University of Pittsburgh Medical Center Presbyterian flared in early September when mold was discovered in the cardiothoracic intensive care unit, forcing the hospital to move 18 patients. On Thursday, mold-borne illness was discovered in a liver transplant patient who died at UPMC Montefiore, a second campus of the hospital with no connection to the cardiothoracic unit, the hospital's website said.
