Oral candidiasis or thrush is an infection of the oral cavity by Candida albicans. It was first described in 1838 by pediatrician Francois Veilleux.
Oral candidiasis is generally obtained secondary to immune suppression, whether a patient's oral cavity has decreased immune function or if it is systemic. This immunosuppression is dose-dependent. Examples of systemic immunosuppression are very young or very old age, immunocompromising conditions such as HIV/AIDS, and chronic systemic steroid/antibiotic use. An example of local immunosuppression is inhaled corticosteroids (often in the preventive treatment of asthma and chronic obstructive pulmonary disease). For this reason, patients using such medications are instructed to rinse their mouth with water after each use. Oral thrush is transmittable via kissing as well as breastfeeding.
