A wrongful death lawsuit has been filed against UPMC Mercy Hospital and two of its physicians over allegations that a patient contracted Legionnaires’ disease while receiving care at the Pittsburgh facility.

According to the claim, a woman from Jefferson Hills says her husband became infected with Legionnaires’ disease during his hospital stay and later died. The lawsuit names both the hospital and two doctors as defendants.

The case centers on whether the illness was acquired at the hospital and whether the patient’s death is connected to that infection. Legionnaires’ disease is a serious form of pneumonia caused by bacteria that can spread through contaminated water systems.

The lawsuit adds to concerns that can arise when severe infections are allegedly linked to medical settings. Based on the information released so far, the legal action seeks to hold the hospital and the physicians responsible for the patient’s death.
