AR—attack rate. ${\mathrm{C}}_{\mathrm{R}}$—situation-related factor (SF) considering the air change rate, deposition, inactivation, room volume and time of stay. ${\mathrm{C}}_{\mathrm{R},\mathrm{steady}}$—situation-related factor in a steady situation considering the air change rate, deposition, inactivation, room volume and time of stay. Q_b,in—inhalation flow rate of the susceptible persons. f_M—mask efficiency considering the inhalation and exhalation efficiency. $\frac{{\mathrm{S}}_{\mathrm{v}}}{{\mathrm{N}}_0}$—virus emission rate of the infectious person divided by the critical dose. ${\frac{{\mathrm{S}}_{\mathrm{v}}}{{\mathrm{N}}_0}}_{\mathrm{steady}}$—virus emission rate of the infectious person divided by the critical dose in a steady situation.
