Predicted Infection Risk via Aerosols	2020-10-12		.txt	text/plain	4012	284	62	34 In order to perform an infection risk assessment for the airborne transmission in the far field 35 and to introduce appropriate preventive measures, it would be necessary to know the amount The so-called aerosols (liquid or solid particles in a dispersed phase with a fluid) as well as 50 droplets differ by size. In equation (3), the number of infectious persons (I), the quanta emission rate depending on 74 the activity (q), the pulmonary ventilation rate of exposed susceptible persons (Qb), the 75 duration of stay (t) and the volume flow of pathogen free air (Q) was used. To calculate the predicted 156 infection risk via aerosols (PIRA) in the far field of a room the concentration of quanta (c(t)) 157 and the respiratory rate (Qb) has to be known. To reduce the risk of infection via aerosols the necessary volume flow of virus-free air 327 depending on the exposure time can be seen in Figure 5 .	./cache/cord-103576-g5de4fwj.txt	./txt/cord-103576-g5de4fwj.txt
