From WikiMD's Wellnesspedia

Infectious Disease is a medical specialty focused on diagnosing, treating, and managing infections caused by bacteria, viruses, fungi, and parasites. These diseases can range from common infections to complex, rare, or life-threatening conditions.

Overview[edit | edit source]

The field of Infectious Disease encompasses the understanding of the pathogenesis, epidemiology, and immunology of infections. Specialists in this field, known as infectious disease physicians or infectious disease specialists, are experts in infections of the sinuses, heart, brain, lungs, urinary tract, bowel, bones, and pelvic organs.

Diagnostics and Treatment[edit | edit source]

Infectious disease specialists use a variety of diagnostic tests to determine the cause of an infection, including blood tests, cultures of wound, and respiratory secretions, and advanced imaging tests. Treatments may involve antibiotics, antivirals, antifungals, and antiparasitics.

Training and Expertise[edit | edit source]

Physicians in this specialty complete extensive training, including medical school, a residency in internal medicine, and a fellowship in Infectious Disease. They are knowledgeable in the use of vaccines, immunoglobulins, and other forms of immunoprophylaxis and infection control.
