"Could" go to school?

I absolutely agree with the first statement, but what the hell are they thinking in the second sentence. What exactly does this mean? Are kids still allowed to go to classes? Who decides if it is necessary? What does necessary entail? As long as they're not dead children are fit for classes? Until they drop dead it's OK to show up in class and infect everyone else? Good call morons...
