We present the viral load in the air and deposited around the person, and show that wearing even a simple cloth mask substantially decreases the extent of spatial spread of virus particles when an infected person coughs or sneezes. 30 Here, we employ Computational Fluid Dynamics (CFD) simulations to address the influence of homemade face masks on the turbulent clouds that result due to sneezing events, and on the lateral extent of spread of ejecta. When an infected person not wearing a mask sneezes or coughs, virus particles in the large droplets rapidly drop to the floor. Our simulation results conclusively demonstrate that wearing even just a simple cotton mask has a dramatic influence on the air flow and spread of ejecta after a respiratory event.	./cache/cord-148354-3nl3js2x.txt	./txt/cord-148354-3nl3js2x.txt
