Answer: Thrush (this one is know it other countries) or Candida
Candidiasis is a fungal infection caused by a yeast (a type of fungus) called Candida. Some species of Candida can cause infection in people; the most common is Candida albicans. Candida normally lives on the skin and inside the body, in places such as the mouth, throat, gut, and vagina, without causing any problems. Candida can cause infections if it grows out of control or if it enters deep into the body (for example, the bloodstream or internal organs like the kidney, heart, or brain).
Candidiasis is a fungal infection due to any type of Candida (a type of yeast). When it affects the mouth, in some countries it is commonly called thrush.
