My dad ate taco bell last night @9pm, and started experiencing flu-like symptoms around 9am today. The symptoms were diarrea and vomiting. He started feeling better around 5pm. My mom and him were supposed to fly out to see me and my family today, but canceled their flight because they did not want to come here and get us sick. I am trying to learn about the major differences between the flu and food poisoning. We all know Taco Bell can be kinda sketchy. hehe

Influenza has respiratory symptoms whereas food poisoning doesn't.

You don't usually get diarrhea with the flu.

Food poisoning: fever, chills, diarrhea, abdominal pain, cramps.

Flu: body aches, fever, chills

With food poisoning you will get heavy stomache and colon aches and cramps.
This does not happen with flu

All the other symptoms like possibly headaches, vomiting, nausea,diarrhea, fever, overall feeling sick is quite the same
