On May 1, 2018 a single regulation (Ontario Regulation 134/18 under the Health Protection and Promotion Act or HPPA) came into effect to streamline and provide clarity on disease designation for Ontario's health care providers who are required to report to public health should they suspect or have confirmation of any of the included diseases or their etiologic agents. Previously, these diseases were referred to as the "reportable diseases". You can also download this list as a PDF.
The following diseases were added to the list:
- Carbapenamase-producing Enterobacteriaceae (CPE)
- Echinoccoccus multilocularis
The following diseases were removed from the list:
- Yellow fever
These diseases were removed as they do not require direct public health action to mitigate transmission in Ontario. Should this change, the Minister of Health and Long-Term Care has the authority to take action and amend the regulations accordingly.
A list is available to download as a PDF from TBDHU.COM/diseases. The diseases requiring immediate reporting to public health are marked with an * on this list. The remaining diseases can be reported as soon as possible and at least by the next working day.
Patient consent is not required for reporting this information. The Personal Health Information Protection Act (PHIPA) explicitly allows health care providers to disclose information to the local Medical Officer of Health for purposes outlined under the HPPA.
Please contact the Infectious Diseases program with any questions at 625-8318 or toll-free at 1-888-294-6630, ext. 8321 (Monday to Friday, 8:30am to 4:30pm).
This reportable diseases toolkit for health care providers has been adapted with permission from the Leeds, Grenville and Lanark District Health Unit. Each of the diseases is listed in the navigation menu on the left-hand side of the page (or below on a mobile device).
The goal of this toolkit is to improve accessibility to credible and up-to-date information on Ontario’s diseases of public health significance in a format that is quick and easy to use, all in one location.
The information available for each disease includes reporting requirements, epidemiology, risk factors, diagnosis and testing, treatment and case management (if applicable), patient fact sheet, and additional resources with links attached.
We welcome your feedback on the use of this toolkit. If you have any questions or comments OR are interested in completing a short survey, please contact us at email@example.com. Please do not include confidential information. You can also call 625-8318 or toll-free 1-888-294-6630 ext. 8318 to speak to a member of the Infectious Disease Team. The TBDHU values your input and will take your comments into consideration as it continues to review and update this resource.
