The COVID-19 pandemic has demonstrated the importance of developing national bed resources and the human resources of medical workers, taking into account the need for rapid conversion of somatic hospitals. Doctors, mid-level and junior medical personnel are at higher risk of infection both through contact with patients if they do not follow the rules for using PPE, and when interacting with each other. Repurposed somatic hospitals (GBUZ SB «SOKB named after V.D. Seredavina», FGBI VO «Clinics of SamSMU»), in comparison with a specialized infectious diseases hospital (GBUZ SB «GBS № 6»), due to the peculiarities of construction and planning solutions, represent an environment with a higher risk of infection of medical personnel, which requires additional organizational preventive measures. In addition to the general requirements of biological safety in the repurposed red zone, a comprehensive formation of a safe working environment is required, including such components as: organization of rest rooms for staff separately from the residents, development and observance of a meal schedule to eliminate the intersection of personnel flows as much as possible, digitalization of medical documentation, time-limited reception of biomaterial in the laboratory, issuance of the results of research through an electronic information system.
