Infectious diseases

Infectious diseases deals with a range of secondary diseases due to an infection caused by bacteria, viruses, fungi or parasites. Patients often require highly-complex diagnostic tests to ensure they receive treatments that specifically target the infectious agent to treat the infection.

Why do I need to see a specialist?

Infectious diseases is the medical specialism that diagnoses, investigates and treats infections caused by micro-organisms, such as:

  • bacteria
  • viruses
  • fungi
  • parasites

These infectious agents can be acquired by:

  • direct contact with another person (skin-to-skin contact, sexual intercourse, etc.)
  • contact with a specific environment (water, animals, ticks, etc.)
  • staying in a hospital or other healthcare facility (healthcare-associated infections)

In some cases, infections may penetrate the body to affect all the organs. Fever and chills are common symptoms of infectious diseases, but patients can experience a wide variety of symptoms

Infectious diseases usually require complex diagnostic tests to identify the pathogenic micro-organism involved and target the treatment accordingly.
