Objective. To assess trends in COVID-19 incidence and its structure in the Moscow Region over 2020–2022.
Materials and methods. The authors carried out a retrospective epidemiological analysis of morbidity rates for the period of March 30, 2020 to May 29, 2022, by using data from Russian Federal Service for Supervision of Consumer Rights Protection and Human Well-Being Report No. 970, the data visualization and analysis service in Yandex DataLens, as well as a statistical analysis software platform of IBM SPSS Statistics v.26.
Results. In the Moscow Region, there were 5 periods of a rise in COVID-19 incidence: 1) March 30 to August 30, 2020; 2) August 31, 2020 to May 9, 2021; 3) May 10 to September 12, 2021; 4) September 13, 2021 to January 9, 2022; 5) January 10 to May 1, 2022. The maximum incidence rate in each of the following period was higher than that in the previous one: 88.40/0000 in Period 1, 141.7 0/0000 in Period 2, 236.10/0000 in Period 3; 265.30/0000 in Period 4, and 976.20/0000 in Period 5. Men and women older than 50 years were risk groups. There is a decrease in the number of severe forms of the disease from 6.2% in Period 1 to 0.6% in Period 5 and in the proportion of pneumonias in Periods 4 and 5: 56.7 and 7.5%, respectively.
Conclusion. There were 5 rises in the incidence rates in the Moscow Region and a decrease in the severity of the course and proportion of pneumonias in the pattern of clinical forms of COVID-19, which is associated with SARS-CoV-2 variability.
