Features of the incidence and course of COVID-19 among medical workers of private healthcare organizations of JSC "Russian Railways"

Abstract

Healthcare workers are at risk of contracting new coronavirus infections (COVID-19) due to their job responsibilities. The study aims to explore the incidence of a new coronavirus infection of medical workers of private healthcare organization (PHO) of JSC "Russian Railways". To analyze the incidence of COVID-19 among medical workers of PHO of JSC "Russian Railways", we used the data of weekly monitoring conducted by the company from 5.04.2020 to 28.03.2021. The χ2 method was used for statistical processing. The epidemiological data were also smoothed by linear filtering using 2 points. A feature of the medical service of PHO of JSC "Russian Railways" is the continuous nature of its activities. 5 hospitals were converted to COVID hospitals. 12.9% of cases of COVID-19 were recorded among employees of PHO of JSC Russian Railways. The minimum number of cases was registered on the Far Eastern and East Siberian Railways. The maximum number of cases was noted on the South-Eastern and Northern railways. 94% of the sick were on outpatient treatment. Half of the sick are nurses. The testing of medical workers of PHO of JSC "Russian Railways" revealed a higher percentage of people with IgG to the SARS-CoV-2 virus than the number of cases registered. This may indicate an asymptomatic course of the disease in medical workers. Conclusion. The data obtained indicate the effectiveness of preventive measures to protect medical workers of PHO of JSC "Russian Railways" from a new coronavirus infection. The conducted research will increase the effectiveness of preventive measures in the other PHO.
