Diseases of Public Health Significance (Reportable to Public Health)

Public Health investigates and manages persons with diseases of public health significance under the authority of the Health Protection and Promotion Act R.S.O. 1990, c.H.7. We:

  • Provide information on childhood diseases and diseases of public health significance
  • Provide guidelines on how long an ill child should be kept home
  • Recommend infection control measures to prevent further spread of the disease in the child care centre
  • Provide advisories to parents and staff for information

Licensed child care centres are legally required under the Health Protection and Promotion Act to report any child with a known or suspected disease of public health significance to Public Health. Information about illnesses can also be found in A Guide to Common Infectious Diseases for Child Care Centres (PDF, 25 pages, 1.3 MB) where the diseases that must be reported to Public Health are highlighted in blue.

To report a child with a disease of public health significance call the Reportable Disease Intake Line at 1-800-265-7293 ext. 4752 with the following information:

  • First and last name
  • Date of birth
  • Gender
  • Home phone number
  • Home address
  • Parent/guardian name
  • Date of onset of illness
  • Name of child care centre
  • Person reporting (first and last name)

Chickenpox reporting

Chickenpox is a disease of public health significance and is reportable to Public Health. We collect and report the total number (aggregate counts) of chickenpox cases by age group each month to the Ministry of Health. This information is valuable in establishing the rates of infection in different age groups, especially since the chickenpox vaccine was added to the Publicly Funded Immunization Schedule in Ontario. Use the Chickenpox Monthly Case Report form (PDF, 1 page, 130 KB) to report total number of chickenpox cases monthly and fax it to the Reportable Disease Fax Line at 1-855-934-5463.
