Risk factors, timing and frequency of occurrence of post-COVID syndrome in workers with intensive computer workload

Abstract

According to leading experts of the World Health Organization, the threat of a new strain of SARS-CoV-2 coronavirus remains, which will lead to a sharp increase in morbidity and mortality. The severity of complications after COVID-19 depends not only on how severe the disease was, but also on other factors: genetic predisposition, age, concomitant diseases, and working conditions. This makes it urgent to conduct further scientific research on the ranking of the factors of the production environment that accelerate the spread of COVID-19. The study aims to determine the degree of occupational risk, taking into account the timing and frequency of manifestations of post-COVID syndrome (U09.9; U10.9 according to ICD–X) in specialists with intensive computer workload. In the period 2020–2024, the researchers conducted a survey at the workplaces of Kislovodsk enterprises and examined 556 people with an intensive computer load associated with servicing the flows of mass consumers during the pandemic and in the post-pandemic period. We have studied the timing and frequency of the occurrence of post-COVID syndrome, objectified by the degree of health risk factors in various categories of workers with intensive computer workload. The timing and frequency of seven post-COVID syndrome manifestations ranked (according to the degree of occupational health risk factors) (U09.9; U10.9 according to ICD-X) that occur in workers with intensive computer workload in the first two weeks after discharge from the hospital during hospitalization for COVID-19 (occupational health risk factors category A) or arising within three to four weeks after discharge from the hospital during hospitalization for COVID-19 (occupational health risk factors of category B). Based on statistical and clinical and hygienic data obtained in the period from 2020 to 2024, post-COVID manifestations in the gradations of "high" and "moderately high" occupational health risk for employees (n=556) with intensive computer load were ranked by the timing and frequency of occurrence of the named syndrome, as well as by the degree of risk of potential COVID-19 infections of the named groups of specialists associated with servicing mass consumer flows infected with constantly mutating representatives of enveloped RNA viruses. According to the degree of occupational risk to the health of persons with intensive computer workload, six groups of specialists associated with servicing mass consumer flows, potentially infected with COVID-19 and other representatives of enveloped RNA viruses, were ranked. Limitations. Post-COVID syndromes that occur within one to two and three to four weeks after discharge from the hospital have been studied. Ethics. Scientists have conducted research in accordance with the principles of biomedical ethics and approved by the local Ethics Committee of Izmerov Research Institute of Occupation Health, Moscow (Protocol No. 4 dated 04/14/2021). Each participant of the study submitted a voluntary written informed consent signed by him after explaining to him the potential risks and benefits.
