The key evidence on the safety and impact of reopening schools has been published by the government’s scientific advisory group, Sage.
Sources involved said the risk of coronavirus to pupils going back to the classroom was “very, very small, but it is not zero”.
And that teachers were not at above average risk compared with other occupations.
However, there is much uncertainty throughout the advice.
Is it safe to reopen schools?
The documents say they “cannot be clear” on the extent schools could be reopened without leading to cases taking off in the UK again.
And while it is clear-cut that children are far less likely to be severely ill, there is contradictory evidence on how likely they are to be infected or to spread the virus.
