Estimating the productivity cost of administrative duties and work-related engagements from submission trends during COVID-19 pandemic lockdown.

During the initial months of the coronavirus disease 2019 pandemic, mBio experienced a large increase in the number of submissions, a phenomenon that was also observed for journals of different fields. Since most research laboratories were closed, this increase cannot reflect increased research activity. In this editorial, we propose that the increase in submissions reflected the release of a backlog of unpublished work following a reduction in work-related engagements including scientific travel, which in turn provides an estimate of the productivity costs of such activities on research output.
