A hospital is responding to allegations in a lawsuit that they didn’t take proper precautions in the death of a Lake County child. The parents of Ryland Joseph are suing the University of California Regents over their son’s death at University of California, San Francisco Medical Center. The Josephs allege the hospital knew that bacteria causing legionnaire’s disease was in its plumbing system. The hospital’s response to the suit states that it “exercised reasonable diligence at all times.” They also say that the child’s death was “the natural course” of his condition or “the natural or expected” result of reasonable treatment rendered for his disease. Ryland contracted legionnaire’s disease at the hospital a few weeks after he’d undergone a bone marrow transplant.
