This is a good article about how the number of cases in schools are already escalating:
Covid in SchoolOn the plus side, the vast majority of kids are asymptomatic. They have 10 days at home, and then come back in.
On the minus side, it all adds to the figure, so may affect potential 'release dates' for lockdown, and they go home to infect family members.
Can't offer any solutions - I much prefer having the kids in school, and teaching face to face (or is it mask to mask

)
