There are the general guidelines out there, but the basic information that parents need to deal with—and it's good common sense, but we don't always apply it—is that if you have a sick child, it's not the time to send them to infect other children. Having our kids understand about handwashing, how to cough, making sure that we keep contact surfaces clean as much as we can, knowing that the day care or the school are also reinforcing those, those are all important, and also knowing, whether it's a child or an adult, that if you're becoming severely ill, particularly with something like influenza, if you have shortness of breath, if you have chest pain, that is not something to wait and see about. On the other hand, if you have milder symptoms, there are things such as Tylenol, comfort, lots of fluids, etc.
These are all things that are not mysterious but need to be constantly reinforced. Certainly we do know that the virus spreads in schools, it spreads in communities, etc., but we also know that where kids are educated, supported, and observed, they're more likely to get the appropriate care they need.
