摘要

An object of the present invention is to provide a method for easily evaluating whether there is a risk of aerosol infection in a space having a defined volume. A method for evaluating the risk of aerosol infection according to the present invention includes a releasing step S10 of releasing a plurality of fine particles into a space having a predetermined volume, and after the releasing step S10, releasing the plurality of fine particles in the space. The number of particles is measured multiple times, and the relationship between the elapsed time from the end of the discharging step S10 and the number of the plurality of particles to be measured is specified until the number of particles decreases to a predetermined number. A specifying step S20 of deriving the time and specifying the reduction capability of a plurality of particles in the space from the specific elapsed time; and evaluation steps S30, S34 of assessing that there is a risk of aerosol infection within the body.
