Infectious Diseases

Infectious diseases are caused by pathogenic microorganisms, such as bacteria, viruses, parasites or fungi. These diseases can be acquired from another person, 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 including:

  • infectious disease surveillance, epidemiology, and data analysis and reporting
  • case, contact and outbreak investigation and management
  • prevention, control advice and support
  • education and training
  • laboratory testing
  • 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.
