I'm surprised to learn some areas schools haven't broken up yet.
I'm in new tier 4, and schools here broke up on Thursday or Friday. They are due back on 4th or 5th January, and then in secondary only years 11 and 13 will be in for the first week. So just over 3 week break, and in our area, we arent allowed to mix indoors or outdoors, only essential shops are open with announcements about only 1 adult shopping at a time. Plus its pissed it down so not really good "meeting up for a walk and chat" weather.
While it might have been spreading amongst children in school at the end of term, surely a 3 week break will have greatly curtailed that by the time they go back?
Any children returning to school in January with covid, must logically have caught it from adults working/shopping, or from being allowed by their parents to mix even though its against the rules here.
If parents aren't going to keep to the rules and therefore infecting their dcs, what's the point in shutting schools?
Either this 3 week school break will dramatically reduce the numbers in tier 4, or closing schools doesn't work.
