Infectious diseases are caused by pathogenic microorganisms, such as bacteria, viruses, parasites or fungi. The diseases can be spread from one person to another, directly or indirectly, through fluid exchange or exposure to vectors, or from the environment. Public Health Ontario provides public health and health care partners with information, tools, and resources for the prevention and control of infectious diseases.
This includes infectious disease surveillance, epidemiology, and data analysis and reporting; case, contact and outbreak investigation and management; prevention, control and treatment advice and support; education and training; laboratory testing; and consultation. Areas of expertise include immunization and vaccine-preventable diseases; enteric, zoonotic and vector-borne diseases; and a wide range of infection prevention and control programs for health care and long-term care settings.
