Other European countries eg Denmark have reopened schools.
I will be entirely happy for schools to be reopened just like Denmark's WHEN OUR DAILY DEATH AND INFECTION RATES ARE THE SAME AS DENMARK'S WERE WHEN THEY RE-OPENED THE SCHOOLS.
We closed schools to the vast majority of pupils when there were 40 deaths per day. Why is it safe to return when the deaths per day are over 10x that number, and when 1 in 400 people (as measured by a large randomised sample) currently have COVID?
In a 'bubble' of 15 plus a teacher, there are easily 50-60 people - the households of those children + adult - directly linked by a virus transmission route (mixing in school, not socially distanced). It is extremely likely that some of the children in different bubbles will in fact be siblings or half-siblings who live in the same household, and for there to be linked 'chains' of infection throughout the school via these households.
So with 3 year groups returning - 90 children + at least 6 staff in a 1 form entry school, plus vulnerable / keyworker childcare probably adding another group at least [as more will come in if siblings are in school in returning years] you are easily up to 400 people, all connected via a combination of the school and home environments., even if everyone still maintains ALL of the other social distancing rules (unlikely)
If 1 person in that network is infected, then it can be transmitted to them all - as admitted by the chief scientific advisor to the DfE in that extraordinary meeting with MPs.
I will say again, as I have said many times: it is not that children will die (that is very unlikely). it is that their parents, teachers and grandparents, and those elderly or vulnerable people who those people work with or care for who will die, as a result of this policy.
