[Prevention of acute intestinal infections based on the epidemiological surveillance system].

The development of the system of epidemiological surveillance and its introduction into the practical work of the district sanitary and epidemiological station made it possible to decrease morbidity in acute intestinal infections 2.4 times in comparison with preceding years, as well as to put an end to the outbreaks of these infections. The work proved the advantage of epidemiological diagnosis permitting the introduction of measures which prevent the formation of the epidemic strain of the infective agent and thus affect the seasonal rise of morbidity.
