Abstract

The etiological nature of nosocomial infections is determined by a wide range of microorganisms, which includes both pathogenic and opportunistic flora, the border between which is often rather blurred. Nosocomial infection is caused by the activity of those classes of microflora, which, firstly, is found everywhere and, secondly, is characterized by a pronounced tendency to spread. Identification of developmental features and assessment of the epidemic process of nosocomial infections in hospitals of various profiles made it possible to develop a scientifically grounded complex of organizational, methodological and practical measures to improve the system of epidemiological surveillance in these hospitals.
