Quoting Melissa Cumbee:" The media is doing what they do every other year: blowing things completely out of proportion. It's just ... [snip!] ... if they have the flu they won't show up anyway. Besides, you've had the flu shot so there shouldn't be anything to worry about."
I get the media blows things out of proportion but I don't think they are with this one. I know at least a hand full of people who have gotten this flu. Before this one, whenever there was an outbreak I wouldn't even personally know anyone with it and the peple that I know have gotten don't even live in the same state or are related so it's not like they passed to eachother.
OP like other's have said, of someone has the flu I thought they show up, just have your shower. If you want you can provide hand sanitizer for everyone to use.
