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 inside the body (in places such as the mouth, throat, gut, and vagina) and on the skin without causing any problems.2 However, in certain patients who are at risk, Candida can enter the bloodstream or internal organs and cause an infection. A Candida bloodstream infection, also called candidemia, is the most common form of invasive candidiasis.1 In the United States, candidemia is one of the most common causes of bloodstream infections in hospitalized patients,34 and it often results in long hospital stays and death. It is also responsible for high medical costs.5

Antifungal medication can treat invasive candidiasis. Certain patients such as those with cancer or bone marrow or organ transplants might receive antifungal medication to prevent invasive candidiasis.6
