Question: is vomiting and diarrhea a symptom of the flu?
Answer: The fever and aches usually stop in a few days. But the sore throat, cough, stuffy nose, and tiredness may continue for a week or more. The flu also can cause vomiting, belly pain, and diarrhea. But if you have only vomiting and diarrhea without the other flu symptoms, you probably have gastroenteritis.
