What do we know about the effect of school openings on Covid-19 transmission?
As children return to the classroom, reassuringly some studies show that they have a very low transmission rate — but there is also evidence that closing schools is still the single most effective intervention measure, report ROX MIDDLETON, LIAM SHAW and JOEL HELLEWELL
If children can still transmit the virus, the question then turns to whether school attendance might act as a way for the disease to spread between households that are otherwise not in contact

ON March 8, in just under a week’s time, all schools in England can re-open and around 10 million children will return to school. Many parents and teachers are understandably worried about the effect that this will have on coronavirus transmission. The thousands of deaths from Covid-19 in the first few months of 2021 are a painful reminder of what unmitigated transmission can result in.

Nearly a year on from the first nationwide lockdown in Britain, what have we learned about infection in children and the potential for transmission in schools?

Thankfully, one pattern that has been repeated across the world is that children are far less likely to experience severe disease. While they may still be infected, they make up a tiny proportion of hospital admissions and deaths due to Covid-19.
