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.

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.
