If the schools were closed and they stayed at home, that would be fine. The problem is that instead they will be milling around shops, shopping centres, and public transport, spreading it to people who actually need to be in those places. The difference between schools and other public gatherings is that in the schools they have already been mixing with that group. At a sports event people travel from far and wide, and they then return home. If it can be restricted to certain geographical areas that will help the system to cope.
