[Substantiation of an algorithm of sanitary measures to improve quality of drinking water]

The authors analyzed different data available in the literature, reports of inspection of sanitary-and-epidemiological facilities and departments for ensuring the standard quality of water, and the results of long-term activities to eliminate the negative influence of water agent on morbidity. The protocols of epidemiological investigations of water-induced outbreaks of acute intestinal infections (AII) in the Republic of Byelarus in 1987-1997 were explored. The duration of outbreaks of water-borne AII in the country in these years was found to depend on the time of elaboration of an effective scheme of measures and on that of properly informative analysis of the established situation due to the quality of routine drinking water supply for the population. The more rapidly these measures are implemented, the shorter the outbreaks of AII are. An algorithm (schemes of laboratory control and measures) is substantiated and introduced for working out measures to eliminate the cause of water quality deterioration in the central water supply system.
