[Approaches to the study of the role of water factor in prevalence of Helicobacter pylori infection].

For the present time it became apparent that Helicobacter pylori (Hp) is present in the surface water groundwater wells, in the water from water distribution system. WHO classifies Hp to a group of emerging pathogens for epidemiological surveillance of diseases associated with water. The study, of various aspects of the permeation of Hp into the body of water requires an integrated approach including microbiological, hygienic and epidemiological components. Microbiological research component includes the study of Hp in a water medium at the stages of water preparation, distribution over nettworks and in end users, sanitary hygienic component--hygienic assessment of sources of water supply. The survey of organized cohorts, regularly undergoing periodic health examinations can be one of epidemiological approaches. Using a scanning method and graphical data binding to an electronic map of the studied area with account for residing of examined patients will permit to identify areas and microsections with the highest rates of infection and their conjugation with the character of water using and condition of water supply network
