Based on a review of literary sources, it was established that W. Wells (1934) studied the evaporative-drop mechanism of respiratory drops. His discovery made it possible to create a theory of the propagation of drops and drop nuclei. The Wells droplet evaporation curve is important in explaining the transmission mechanisms of airborne and large droplet infections. The two-meter social distance rule is based on the calculations of W. Wells. It should be noted that biophysical studies of coughing and sneezing directly in the context of the COVID-19 pandemic have not been conducted. The risk of infection is reduced by maintaining social distance, but is not reduced to zero. However, social distancing and wearing a mask outside provide excellent protection.
