– Flu symptoms caused
by the influenza virus are fevers, chills, body aches, stuffy nose, runny nose, severe cough. Sometimes people even have
gastrointestinal symptoms like nausea, and diarrhea, and vomiting. Patients sometimes think
that I have the flu means I have the stomach
flu or I have a cold. And so there are some
times that other things sound like the flu, but in
reality they’re not influenza.
