Yeast Infection, commonly called Candidiasis or thrush, also known as “Candidosis,” “Moniliasis,” and “Oidiomycosis,” is a fungal infection (mycosis) of any of the Candida species, of which Candida albicans is the most common. Candidiasis encompasses infections that range from superficial, such as oral thrush and vaginitis, to systemic and potentially life-threatening diseases. Candida infections of the latter category are also referred to as candidemia and are usually confined to severely immunocompromised persons, such as cancer, transplant, and AIDS patients.
Superficial infections of skin and mucosal membranes by Candida causing local inflammation and discomfort are however common in many human populations. While clearly attributable to the presence of the opportunistic pathogens of the genus Candida, candidiasis describes a number of different disease syndromes that often differ in their causes and outcomes.
