Secrets of COVID-19 transmission revealed in turbulent puffs

Researchers have developed a new model that explains how turbulent puffs, like coughs, behave under different environmental conditions. They found that at environmental temperatures 15°C or lower, the puffs behaved with newly observed dynamics, showing more buoyancy and traveling further. Their findings could help scientists better predict how turbulence and the environment affect airborne transmission of viruses like SARS-CoV-2.
