[Role of the aqueous factor in the epidemiology of dysentery].

Analysis of the dynamics and territorial distribution of bacterial dysentery morbidity during 1959-1973 in the Dagestan ASSR demonstrated that the epidemically unfavourable conditions were largely connected with the use of water in open water bodies for domestic purposes and swimming as well as a wide network of irrigation canals. Persistence of the water factor in the dysentery epidemiology was connected with the ever increasing contamination of water in open water bodies and neglect of sanitary-hygienic requirements of the water supply to population of pertinent and sanitary laws.
