Investigators, led by Professor Dimitris Drikakis of the University of Nicosia, who published in the journal Physics in Fluids of the American Institute of Physics, created a computational simulation that calculates how far droplets can travel from a person who coughs. of his saliva, which may contain the virus SARS-CoV-2…
