“…All the included studies were observational, and they estimated the effect of workplace closures at a population level alongside other interventions. Most studies (92%) observed a beneficial effect of workplace closures alone or in combination with other interventions to reduce incidence [15,24,25,27,29,32,46,52,[244][245][246][247][248][249][250] of COVID-19 and transmission [18,23,24,33,35,38,39,43,48,49,251] of SARS-CoV-2. A study that reported the examined effect of workplace closures alone estimated that non-essential workplace closures across 13 countries in Europe from March to May 2020 were estimated to reduce the change in deaths by 4% points (95% CI: 0.5, 7.4 pp).…”
