[A scientific providing for the system of hygienic optimization and anti-epidemic safety of rail ridership].

The system of scientific and reasonable measures for hygienic and anti-epidemic providing of rail ridership is elaborated. The legal and methodical base for precautionary and current sanitary inspection in the field of hygiene and epidemiology of ridership has been created, standard and methodical documents have been introduced in practice of medical sanitary health services of the railroads and accepted to realization by the design, car-building and car-repair organizations. Sanitary and hygienic monitoring for rail ridership, including control for sanitary, hygienic and microbiological indices of the air environment of passenger and service premises of stations and passenger trains, and also control for indices of health of the workers providing ridership, with use of pre-nosological symptoms of pathology is organized. Features of a bacterial aero-plankton of passenger objects are revealed. The increase of indices of bacterial pollution of air in passenger objects during the summer-autumn periods of year in comparison with winter period is established. Direct relationship between levels of bacterial air pollution of passenger rooms of stations and integrated indices of anti-infectious stability of an organism of workers of the railway stations serving ridership, and also number of persons with the changed indices of the immune status is revealed.
