The thing about schools that no one seems to be able to grasp is how being community hubs they are problematic.
They are places where large numbers are in close proximity to each other in the worst environment possible for transmission. They have hundreds of people linked to them.
We know that the worst places for transmission have been care homes and hospitals. And other institutions where adults are all in close contact for long periods. In those cases we have found ways of restricting access and using protection. Even supermarkets have been doing this to a degree.
Schools remain the only place where this isn't happening and its only been possible because of lower transmission between children.
That's no longer true and that causes a fundamental problem. Schools now pose a risk to the wider community which was not as true previously. And they pose a greater risk to those who attend them - though for children the risk is more of a mild nature.
There seems to be a fundamental inability to understand this.
The situation previously has changed.
Primary schools being kept open is less about education and more about economic productivity for their parents. Though the Conservative Party will never openly admit this.
