Definition of Invasive Candidiasis

What is invasive candidiasis?

Invasive candidiasis is an infection caused by a yeast (a type of fungus) called Candida.  Unlike Candida infections in the mouth and throat (also called “thrush”) or vaginal “yeast infections,” which are localized to one part of the body,  invasive candidiasis is a serious infection that can affect the blood, heart, brain, eyes, bones, or other parts of the body.¹

Candida normally lives in the gastrointestinal tract and on skin without causing any problems.² However, in certain patients who are at risk, Candida can enter the bloodstream and cause an infection. A Candida bloodstream infection, which is the most common form of invasive candidiasis, is called candidemia,.¹ In the United States, candidemia is one of the most common causes of bloodstream infections in hospitalized patients,^3–4 and it often results in long hospital stays, high medical costs, and poor outcomes.⁵

Invasive candidiasis can be treated with antifungal medication, and antifungal medication is often given to prevent the infection from developing in certain patient groups.⁶
