Invasive infection due to Candida species is largely a condition associated with medical progress, and is widely recognized as a major cause of morbidity and mortality in the healthcare environment. There are at least 15 distinct Candida species that cause human disease, but >90% of invasive disease is caused by the 5 most common pathogens, C. albicans, C. glabrata, C. tropicalis, C. parapsilosis, and C. krusei. Each of these organisms has unique virulence potential, antifungal susceptibility, and epidemiology, but taken as a whole, significant infections due to these organisms are generally referred to as invasive candidiasis. Mucosal Candida infections—especially those involving the oropharynx, esophagus, and vagina—are not considered to be classically invasive disease, but they are included in these guidelines.Full text*Every 12 to 18 months following publication, IDSA reviews its guidelines to determine whether an update is required.
