There is a reason to admit that small particles flying out of COVID-19 infected person may be the other way of the infection spending. 

Taylor and Francis Group scientific website mentions that small particles do not only leave the mouth while coughing or sneezing but also during talking or even simply breathing. The research was held by specialists from University of California and NYU’s school of medicine. 

Human particles are quite big for carrying the virus. Keeping in mind that there are patients who have no visible COVID-19 symptoms, this problem becomes even more serious. 

Many particles are let out during talking. The louder a person speaks, the higher the risks of getting infected. 

It is hard to tell how far particles can fly. This simply relies on power of expiration and the way the wind blows. However, in any case, it is necessary to keep distance between people.
