<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been having a fever and cough lately, and also my mouth feels strange, almost like its coated with something.  <response>: Based on your symptoms, it is possible that you are suffering from oral thrush, which is a type of yeast infection. Note: The conversation is limited to one back and forth, but in reality the doctor would likely ask more questions and possibly conduct a physical exam to confirm the diagnosis.
