Objective. Analysis of the incidence of the population of Zaporizhzhia region with ÑÎVID-19 during 2020-2023, identification of the features of the spread of cases in different districts and cities, establishment of gender and age differences.
Materials and methods. A retrospective epidemiological analysis of the population's incidence of acute respiratory disease caused by the SARS-CoV-2 coronavirus in the Zaporizhzhia region in 2020-2023 was carried out. The data of the information base of the Epidemiological Surveillance System of the National Epidemiological Service of Ukraine and form No. 1 "Report on individual infections and parasitic diseases" were used".
Results. On the basis of the data of the information base of the Epidemiological Surveillance System of the Epidemiological Surveillance System of the National Epidemiologist of Ukraine and Form No. 1 "Report on Individual Infections and Parasitic Diseases", an analysis of cases of SARS-CoV-2 among the population of the Zaporizhzhia region by age group and gender from 2020 to 2023 was carried out. The monthly distribution of cases among the population is multidirectional, had peak periods that alternated with recessions. It was determined that the maximum number of cases occurred in 2021 – 52.8%, in 2020 and 2022 – 22.5% each, in 2023 – 2.3%.
The distribution of cases of COVID-19 among the population by age groups shows the general trend recorded by the WHO, namely: the age group of 30-79 years accounted for the largest percentage of all cases – 84.0%, up to 9 years inclusive – 2.4%, 10-17 years – 4.0%, 18-29 – 9.6%. But in 2022, there were upward changes among the younger age groups 0-9 years to 6.7% and 10-17 years to 8.1% with a stable value in the age group 18-29 years (9.5%) and a decrease by 8.0% in the 30-79 age group (75.7%).
Conclusions. The conducted research revealed an unequal distribution of cases across districts and cities of the Zaporizhzhia region: 47.1% were in the city of Zaporizhzhia, 22.7% - in the city of Melitopol (7.0%), and the city of Berdiansk (6.7%) and the city of Enerhodar (9.0%), 30.2% - to other districts of the Zaporizhzhia region, and the highest level was stably recorded in the city of Enerhodar (7550.20-9653.89 issues/100 thousand people).
The highest incidence rates are traditionally recorded in the age groups of 30-64 years and in men (3563.22 cases/100 thousand population) and women (4894.57 cases/100 thousand population), but in women their values was 1.5 times higher (p<0.001). In 2021, the incidence rates for both men and women increased by 2.7-2.9 times in all age groups. However, in 2021-2022 observations, the highest values were registered for men in the age group 65 and older (10939.63 and 3539.40 cases/100 thousand population), and for women – in the age group 30-64 (9928.89 and 4148.87 cases/100 thousand population).
