Reopening schools during the COVID-19 pandemic: governments must balance the uncertainty and risks of reopening schools against the clear harms associated with prolonged closure

摘要

Evidence to support the effectiveness of global school closures in controlling COVID-19 is sparse. There is continued uncertainty about the degree to which school children are susceptible to and transmit COVID-19. Balancing the potential benefits with harms involves explicit trade-offs for governments, but there has been little recognition that low-income and middle-income countries face a very different set of trade-offs around school reopening from those in wealthy countries.
