We presented the assessment results of the potential epidemic risk level (PERL) of conditions for
centralized drinking water supply and recreational water use, as potential epidemiological risks for 85
subjects of the Russian Federation. High level of potential epidemic risk of centralized drinking water
supply conditions for 21 subjects of the Russian Federation and increased level taking into account
water quality, water supply of the population, isolation of pathogenic bacteria, virus markers and
registration of the morbidity rate of acute intestinal infections with the implementation of water factor of
pathogens transmission for 60 subjects have been established. When assessing recreational water use, a
high level of potential epidemic risk was determined in 39 subjects, an increased level of potential
epidemic risk was determined in 30 subjects, which indicates the probability of the waterway for the
spread of the cholera pathogen and other acute intestinal infections of bacterial and viral etiology. It is
planned to use in conjunction with other data in determining the epidemic potential of the subject.
