No, the only way it would violate child privacy laws is if they gave out the names of those sick. I worked at a day care and if your child got bitten we couldn't say WHO did the bitting just that your child had been bitten. The same applies here: They don't have to say who at school was sick, but they should inform everyone that the school had an out break. You as parents have a right to know if your child is being exposed, so that, at the very lest, you could watch for signs of flu. The reason they don't want to let parents know about the outbreaks is because of money. Why? Schools get government funds based upon attendance, and they don't get paid for absent childern!
