Background: COVID-19, a new strain of coronavirus, has been declared a global pandemic by the World Health Organization (WHO). The first documented case of the virus was in China in December 2019. Aims: Developing a prognostic chart and planning the use of medical resources for early detection and diagnosis of Covid-19. Materials and methods: The study was conducted using a case-control method. For this, we included 600 cases and 600 healthy controls infected with Covid-19 in 2020-2022, and analyzed their risk factors for developing the disease. Results: Based on our analysis, in 2021 the level of occupancy of positions in this hospital was 95.6% for doctors, 57.5% for junior medical staff, and 52.2% for junior medical staff. From this we can conclude that in 2021, junior medical staff and junior medical staff occupied almost half of the total staff. Conclusion: Widespread use of a prospective table that allows for a comprehensive assessment of the risk group among the population and patients will allow medical workers working in the ENT institutions and heads of healthcare institutions to develop scientifically based measures aimed at reducing the incidence of the disease, its early detection, diagnosis and adequate treatment.
