A group of academics have set out a series of recommendations for schools to reduce the risk of COVID-19 transmission now that they have re-opened, in a letter published in The Lancet.
Lead author Dr Deepti Gurdasani from Queen Mary University of London said: “It’s important to acknowledge the key role schools play in transmission of SARS-CoV-2, and make them safer so as to protect the wellbeing of children, staff, families, and the wider community.”
In the letter, the authors write: “While returning to school as soon as possible is imperative for the education, social development, and mental and physical welfare of children, not enough has been done to make schools safer for students and staff.
“Without additional mitigations, increases in transmission are likely, this time with more infectious and possibly more virulent variants, resulting in further lockdowns, school closures, and absenteeism.”
The authors say that school closures have been associated with substantial reductions over time in the effective reproduction number (Rt) across many countries (including England). In contrast, data from the Office for National Statistics’ 2020 COVID-19 Infection Survey show that the prevalence of infection among children rose above the prevalence for all other age groups before the 2020 Christmas break.
“Multi-layered mitigations can substantially reduce the risk of transmission within schools and into households,” they write. “Making schools safer goes hand in hand with reducing community transmission and is essential to allow schools to safely reopen and remain open.”
The authors make a set of recommendations, in line with guidelines from the US Centers for Disease Control and Prevention and practised in many countries, to reduce the risk of transmission in schools and mitigate the impact of COVID-19 on children and families. These include:
