 First up, coughing, sneezing, fever, running nose, there is nothing unusual about that staff this time a year. But, if it feels like you can't go anywhere without seeing these symptoms of sickness, you might be right, flu seasons here and from what we're seeing, it's a bad one. Check out this map, all those states in red, that's where officials are reporting widespread outbreaks of the flu. There are more than 14 states dealing with that, normally flu season hits its peak around late January, early February, by the end of December, more than 2200 people had checked into the hospital with flu like symptoms. Doctors say it's hard to predict just how bad the flu season might get. But some are concerned that there are so many cases this early in the season. A couple of weeks, I sat down with CNN's Dr.Sanjay Gupta, he is our chief medical correspondent to talk about the flu. One of thing I asked him is, how do you know when you're too sick to go to school. With what symptoms should students stay home, like you wake up, you're not feeling well, at what point should you say I'm not going to school.
