Diseases of Public Health Significance
Duties to report specified diseases
Ontario's Health Protection and Promotion Act (HPPA) (external link) creates a legal duty for physicians and other healthcare professionals/practitioners, laboratories, and hospital administrators to report specified diseases to the Medical Officer of Health. These reporting duties are reinforced by the College of Physicians and Surgeons of Ontario (external link).
Other health professional staff in long-term care homes and rest/retirement homes also have a duty to report suspect and confirmed cases of communicable diseases and outbreaks to the Medical Officer of Health. School partners, through Principals, also have legal duty to report under the same legislation.
Why to report
Reporting of cases of infectious diseases and related conditions remains a vital step in controlling and preventing the spread of communicable disease. These reports are useful in many ways, including assurance of provision of appropriate medical therapy (for example, for tuberculosis), detection of common-source outbreaks (for example, in food-borne outbreaks), and planning and evaluating prevention and control programs (for example, for vaccine-preventable diseases).
Diseases to report
Under the authority of the Health Protection and Promotion Act (HPPA) (external link) and Regulation 569 (external link), suspect and confirmed cases or death caused by or contributing to diseases of public health significance are to be reported to the local Medical Officer of Health.
