Schools in England reopened their doors this week as a first step toward easing lockdown measures. While primary school children have returned as normal, pupils in secondary schools are expected to wear a mask during lessons and take bi-weekly rapid coronavirus tests.

The reopening of schools was a "road map out of lockdown" priority for Prime Minister Boris Johnson and Education Secretary Gavin Williamson, who wanted to ensure schools were the last to close and the first to open. But could a rushed reopening lead to another spike of coronavirus infections?
