Objective. Evaluation of the regional features of COVID-19 incidence distribution depending on the population density of the constituent entities of the Russian Federation (RF), as well as among its individual most epidemically vulnerable social groups.
Materials and methods. The data of weekly epidemiological monitoring and retrospective epidemiological analysis of COVID-19 incidence in the constituent entities of the Russian Federation for the period from January 2020 to December 2022 were used, according to the data of the Centers of Hygiene and Epidemiology of Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing from the constituent entities of the Russian Federation.
Results. The structure of morbidity was studied in terms of clinical forms of the disease. Morbidity in individual social groups was analyzed. The effect of individual risk factors on the morbidity of health care workers as an epidemiologically vulnerable and socially significant category of the population was demonstrated. The features of the incidence of COVID-19 among health care workers are presented.
Conclusion. The regional epidemiological features of morbidity in the population of the Russian Federation were an insignificant effect of population density on the spread of the disease in general, the lowest mortality rates in the group of regions with extremely high population density, as well as the largest contribution of imported cases of COVID-19 to the structure of COVID-19 incidence in regions with extremely high and low population density.
