Abstract
Telework was rapidly introduced as a measure against COVID-19. When examining the spread of telework from a medical perspective, the greatest problem is that the health impact on workers is unknown. Many papers have been published recently, but these have several problems, including the (1) the difficulty of distinguishing between the effects of the COVID-19 crisis and the unique effects of telework, (2) the presence of effects unique to Japan, and (3) the fact that most were cross-sectional studies. Nevertheless, there has been slow but steady progress in occupational health management methods.
