Assessment of the COVID-19 epidemiological situation in St. Petersburg

Abstract

Aim. Identification of epidemiological patterns of the SARS-CoV-2 spread among the population of St. Petersburg during the one-year COVID-19 pandemic period.Materials and methods. The performed analysis focused on the dynamics of COVID-19 cases in St. Petersburg from 2/3/2020 to 4/4/2021 and on the gender-age profile of patients. The information about patients (age, gender, type of the disease, hospitalization, social, and occupational status) was obtained from the database containing the materials from statistical data form No. 058/u.Results. After one year, the dynamics of reported cases of COVID-19 in St. Petersburg shows two cycles of seasonal surge (spring and autumn-winter) and 8 epidemic periods. It has been found that there are no gender-age differences among COVID-19 patients, which can be seen from the relatively similar number of cases among men and women per 100,000 people in each age group during specific epidemic periods. The strong association between clinical manifestations of COVID-19 and the patients' age was detected: Severe cases were more frequently diagnosed in patients over 70 years, regardless of their gender identity. Based on the social and occupational status, the people who were most exposed to the COVID-19 epidemic process were retirees and people whose occupation was associated with health and safety of St. Petersburg. Among the COVID-19 patients, retirees accounted for 13.69% (men) and 17.67% (women). The proportion of healthcare workers was 3.67% (men) and 9.41% (women).Conclusion. It has been assumed that COVID-19 tends to be a seasonal disease featuring annual autumn-winter epidemic cycles. The study addressed prospects of preventive vaccination against COVID-19 in Russia and the importance of tracking the complications pathogenetically associated with the acute phase of the disease in the system of epidemiological surveillance.

Dynamics of university students' experiences with COVID-19 in the first year of pandemic in Russia: dataset

“…In Russia by the middle of April 2020, COVID-19 cases had been detected in all its federal regions. St. Petersburg is one of the largest cities in the country and which has one of the most intensive spread of COVID-19 epidemic (Akimkin et al, 2021 ). The first round of data collection occurred at the peak of the first wave of COVID-19 pandemic in Russia (03/30/2020 to 08/30/2020) with an incidence of 51.31 cases per 100,000 people (Akimkin et al, 2022 ).…”

Spatial-dynamic heterogeneity of the COVID-19 epidemic process in the Russian Federation regions (2020–2023)

“…Анализ научных работ показал, что в России проводились оценки течения эпидемического процесса COVID-19 по «волнам» / периодам подъема заболеваемости и смертности, однако зачастую анализ проводился либо в целом по РФ [8][9][10], либо в рамках одного или нескольких субъектов / федеральных округов РФ [11][12][13]. Отдельные исследования были посвящены определению и сравнительному анализу геновариантов SARS-CoV-2, встречавшихся на территории России в различные периоды течения эпидемического процесса COVID-19 [14,15].…”
