ウイルス感染症対策としてのCO₂濃度の利用にむけた値の解釈について

抄録

Since airborne transmission has been considered as a possible infection route for the novel coronavirus in addition to contact and droplet infection routes, ventilation is an important measure against airborne route. In this paper, we describe the history of setting regulatory standard values and the interpretation of CO₂ concentration as a measure against infectious diseases. Although the standard value of 1,000 ppm is not intended originally for infection control, it is practically useful as a guide value for potential infection risk management.
