Using the Wells-Riley model, for different types of rooms, the probability of airborne transmission and reproduction
number of SARS-CoV-2 coronavirus (together with Delta and Omicron variants) depending on the type of ventilation
and outdoor air flow rate were determined. The analyses were carried out for air flows assumed in the literature and
Polish regulations for particular types of rooms and for the permissible or standard number of persons occupying
them. Various scenarios was also determined and considered assuming typical time of occupancy in particular types
of rooms. The influence of safety rules was also determined and the use of protective masks on the COVID-19 disease transmission by air in rooms.
