If you are going to take her out of school to prevent it, keep in mind that you and your husband will both need to quit work and take up farming to stay out of the grocery store, and give up money - easily the most disgusting thing in our lives (Guaranteed - there is more bacteria on a $20 than in your toilet).
Since that's fairly impossible to do - I think that homeschooling to avoid swine flu is over reacting a tad.
S.
ETA - I apologize if that sounds cruel. It's the truth. When the Pandemic flu of the early 20th century was wiping out villages, there were isolated Alaskan villages that refused to allow anyone to enter - the only way to stay away from something as contagious as the flu. To avoid it, you'd have to avoid the gas stations, the grocery store, the hospital, the pharmacy, and work. To REACT to a scare - any scare - by giving into overcoming, paralyzing fear is not healthy. To pull a child out of school because of fear of an easily transmitted virus, without blocking off other routes to the family - work, park, shopping mall is to not cover the bases.
I fully support homeschooling - and choose it for my children. Reactive homeschooling - whether a parent pulls a child after an incident like Columbine, or the DC sniper, or for fear of the flu or MRSA - is over reacting.
