It is flu season(as well as every other virus out there it seems like). So many people are posting about having the flu. The flu(influenza) can be prevented with a flu shot and tamifu can be prescribed to ease symptoms if you get it, and they do test for it. It is also something that can turn serious if your body cant fight it off, and can commonly lead to pneumonia. This is NOT the same thing as the stomach "flu" that makes you puke or have diarrhea, that is not actually even a "flu" at all. There is no shot to protect against the stomach bug and nothing can really treat it except staying hydrated or taking antinausea medication might help your tummy ache.
