The flu is an upper-respiratory infection. Norovirus is gastrointestinal. Let's look at them side-by-side, shall we?

Michigan officials are warning residents that they're seeing an uptick in the Norovirus, and they're warning people to keep an eye out for the symptoms to avoid the spread of it.

I think it's important that we address the differences between the flu and Norovirus because a lot of people will get the two of them confused.

In short, if you are praying to the porcelain throne and you're not sure which end it's gonna come out of, you've got Norovirus. If you've got a cough, a sore throat, a fever and muscle aches, it's the flu. This has been a public service message.
