The effect of motion of respiratory droplets on propagation of viral particles

Abstract

In this work we investigate viral load propagation due to liquid droplets expelled during respiratory actions. We describe a mechanism of the transmission of such evaporating system and analyze dependence on several ambient parameters for different respiratory processes, such as sneezing, coughing and speaking. Our study has found that a significant amount of viral load and droplets from the respiratory fluid might transfer beyond the customary 2m distance, understanding of which might give us a better insight about regulations and risks posed by an infected individual.
