Oral candidiasis, which is also called thrush, is a fungal infection
of the mouth and/or throat. Candidiasis of the throat is called esophageal
candidiasis (see chart).

While oral candidiasis can sometimes occur without symptoms, the most
common symptoms are discomfort and burning of the mouth and throat and
an altered sense of taste (often described as "bad"). Creamy
white or yellowish spots on the mouth and throat that can be removed by
light scraping are also common. These may be accompanied by cracking,
redness, soreness and swelling at the corners of the mouth. A bad case
can include mouth sores.
Oral candidiasis is rare if CD4+ cell counts are above 500. Outbreaks
are more common as the count drops to 100. Oral candidiasis may be more
difficult to treat when CD4+ cell counts fall below 50.
