Scientists in Finland have modeled how small airborne viral particles spread in a grocery store setting, which may help us better understand the spread of the new coronavirus. For the study, researchers at Aalto University, the Finnish Meteorological Institute, the VTT Technical Research Centre of Finland and the University of Helsinki used a supercomputer to simulate the spread of small viral particles leaving a person’s respiratory tract through coughing. They simulated a scenario in which a person coughs in a store aisle between shelves, and took into account ventilation.
