About This Condition
Infection is the result of invasion of the body by microorganisms, including bacteria, viruses, or fungi.
Not all microorganisms cause infections in the body, and exposure to a disease-causing microorganism does not always result in symptoms. The immune system plays a large role in determining the body’s ability to fight off infection.
Surgical treatment is recommended in some cases to remove diseased tissue, prevent the spread of infection, or drain pus from an infected area.
