Amendments to the Health Protection & Promotion Act Regulations
Ontario Regulation 135/18 (Designation of Diseases) and Ontario Regulation 569 (Reports) under the Health Protection and Promotion Act (HPPA) have been amended.
Effective January 1, 2025, Candida auris (C. auris) is a newly designated Disease of Public Health Significance (DoPHS) and is reportable to the Medical Officer of Health (MOH).
Case and outbreak definitions
Confirmed cases include those who are detected by an accredited microbiology laboratory from active screening and clinical infections.
Suspect outbreaks may be considered in a hospital or long-term care home if:
a single confirmed case is identified in a facility that has not seen a case previously OR
two or more confirmed cases are identified within a facility even if they present on different units and present months apart
Confirmed outbreaks in a hospital or long-term care home occurs when:
evidence of transmission between patients is identified OR
an epidemiological link between patients is identified OR
the hospital or long-term care home considers, based on their policies, transmission has occurred or if the incidence of C. auris at the facility is higher than expected even without a clear link between patients.
Identification, management, and infection control resources
Although the prevalence of C. auris in Ontario is low, the emergence of multidrug resistant organisms within Canadian health care facilities requires an integrated approach to surveillance and infection control across the broader health sector. With no or limited treatment options, even a single transmission event of C. auris is of concern.
C. auris can cause a range of infections, and symptoms are often non-specific. Risk factor-based screening (see screening checklist below) can help to identify clients, patients, or residents at increased risk of having an antibiotic resistant organism.
Public Health Ontario (PHO) disease-specific resources include:
- interim Guide for Infection Prevention and Control (PDF)
- an infographic on Management of a Single New Case of C. auris (PDF)
- Candida auris reference identification and susceptibility testing (PDF)
- screening checklist to identify patients, clients, or residents who may be at increased risk
The Ministry of Health has also posted the attached disease-specific appendix on the Ontario Public Health Standards webpage.
