That is so unfortunate. I feel for you guys.
Our playoffs start Saturday in AZ. Every kid with the sniffles is rumored to have "THE SWINE FLU". My son texted me today because some kid was sick at school and they thought she might have "IT". There are 3,000+ students at the school. I would be willing to bet at any given point in time, somebody is sick with something.
The flu is very hard on the weak (small children, elderly, weak immune system, etc). I think the average ball player would be down for a couple of days, tops. We clearly need to protect against the spread of this, but it's a shame that the media hype for this has gone out of control.
Remember the bird flu a few years ago? How many people got sick? 2?
The only thing I can say is, whatever situation you're in, so is everyone else. You've prepared your kids all season for adversity. This is just a different kind.
Good luck.
