In the absence of a robust evidence base on lockdown exit strategies, we consider the range of options being taken globally to reopen schools with a view to informing the formulation of national plans. Although COVID-19 tends to be less severe in children and adolescents, and thankfully relatively few students have died of the condition, a key policy concern has been that young people may be important community reservoirs for the transmission of the virus to household members. A recent (unpublished) systematic review concluded that children and young people under 20 are 56% less likely to contract SARS-COV2 from infected individuals than adults this suggesting they may play a smaller part in transmission than originally thought [6] . ./cache/cord-284353-f7zkp9cf.txt ./txt/cord-284353-f7zkp9cf.txt
