In a follow-up on the Legionnaires’ disease outbreak at Mount Carmel Grove City Hospital in Ohio, health officials now put the outbreak total to 16, including one death.


In a statement from hospital officials, they note they are confident that they have identified the source of bacteria. Tests received this week from water samples taken May 23 through June 1 showed significant legionella bacteria were in our hot water system at that time.

It is believed the bacteria are linked to inadequate disinfection prior to Mount Carmel Grove City’s opening.
