Deaths of three patients with mold infections baffles the University of Pittsburgh Medical Center, as the facility struggles to find the source of the household mold, according to an article on the CNN website.
WTAE reported that the first two patients who died stayed in the same room in the cardiothoracic ICU.
Mold deposits were found in toilets and behind walls in the unit, and UPMC closed it temporarily and sent in a team to assess and clean the area.
The air quality at teh facility has also been checked for mold. "We have not received any concerning results," UPMC said in a statement, but has replaced all of its germ-catching air filters.
UPMC also is sending in a disinfecting robot to its ICUs to kill any germs with ultraviolet light.
