At this moment, we do not have strong evidence to guide decisions on durations of school closures and how various durations will effect public health. A few days of closure is reasonable in response to school-based cases of COVID-19 for decontamination and contact tracing; while medium to longer lengths of closure (4–8 weeks) may be considered as part of a broader community mitigation strategy. 11 Extending school closure will likely support the overall effectiveness of social distancing and thus aid in lowering the peak of the epidemic curve. The policy should be balanced between public health benefits and the significant societal consequences.
