Monthly Communicable Disease Surveillance Data

The Health Protection and Promotion Act (HPPA) outlines the communicable diseases that are designated reportable in the province of Ontario. A list of these diseases can be found the List of Reportable Diseases web page. Toronto Public Health analyses and reviews data for these diseases on an ongoing basis, and provides monthly summaries of these data. Given that quality assurance checks are completed prior to analysing and posting these data, there is a reporting lag of approximately two months.
