Responsibilities of Healthcare Institutions

Under the Health Protection and Promotion Act (HPPA), healthcare institutions (hospitals, long-term care homes and retirement homes) are required to monitor staff and patients/residents for signs and symptoms of gastroenteric (e.g., nausea, vomiting, diarrhea, fever) and respiratory (e.g., cough, runny nose, sore throat, fever) infections. Healthcare institutions must also actively look for, detect and report suspected and/or confirmed outbreaks to their local public health unit.

Toronto Public Health's Mandate

Under the HPPA, Toronto Public Health is required to respond to reports of suspected and confirmed outbreaks of gastroenteric and respiratory illness. Toronto Public Health works with healthcare institutions to prevent and control institutional outbreaks, including the use of best practices in infection prevention and control.

  • Clean your hands frequently.
