Infectious Diseases

Infectious diseases are illnesses caused by the introduction of harmful microorganisms (pathogens or germs) into the body. They can affect humans, animals, and even plants. Historically, infectious diseases have been a major cause of death worldwide, though advancements in public health measures like vaccines and antibiotics have significantly reduced their impact in many areas. Despite these advances, infectious diseases remain a significant global health challenge, especially in low-income countries.

Infectious Diseases

Infectious diseases or ID, also known as infectiology, is a medical specialty dealing with the diagnosis and treatment of infections. An infectious diseases specialist’s practice consists of managing nosocomial (healthcare-acquired) infections or community-acquired infections. An ID specialist investigates and determines the cause of a disease (bacteria, virus, parasite, fungus or prions). Once the cause is known, an ID specialist can then run various tests to determine the best drug to treat the disease. While infectious diseases have always been around, the infectious disease specialty did not exist until the late 1900s after scientists and physicians in the 19th century paved the way with research on the sources of infectious disease and the development of vaccines.
