No, I do not believe that closing schools is the only way to stop the spread of H1N1.
I believe that every parent should do what the doctors in Omaha, Nebraska did to cure this one little girl of Swine Flu. Child Cured of Swine Flu
The thing that bothers me is that if you go to your doctor tomorrow and ask him about it, he will tell you that this therapy does not work...even in the face of evidence to the contrary.
But your child is better off to get the flu, stay home and allow her natural immune system to 'learn' the virus and build antibodies to it. This can also help to protect her from other strains of flu where she may have some partial immunity.
This may be important especially if these strange new viruses keep escaping from labs or just spontaneously appearing in her lifetime.
