What we call “the flu bug” is really many different viruses. There are two main families: A and B, and both have many individual members, like Influenza A-Moscow, Influenza A-Panama and Influenza B-Sichuan.
While flu symptoms can include headaches, stomach cramps, and diarrhea, more often than not, flu symptoms tend to be muscle aches and sinus problems.
When you have a cold or flu, the doctor (or Dr. Mom) may tell you to drink lots of fluids. But did they ever explain why you need to guzzle all that water and juice?The extra fluid helps prevent dehydration, which can make you feel even worse, and make it harder to get well.
