[Epidemiological determinants of the irregular territorial spread of Sonne dysentery].

The article deals with the results of the study of causes of the pronounced territorial irregularity in the morbidity levels of shigellosis Sonnei. The analysis of the statistical data collected at 15 territories (large and small towns) revealed that differences in morbidity levels were determined mainly by the activity of the alimentary route of the transmission of infection (the degree determination was 78.4%). The levels of consumption of milk and dairy products by the population was the most important epidemiological determinant (the degree of determination was 54.1%). The levels of morbidity in shigellosis Sonnei were greatly influenced by the scope of the population survey for enteric infections, made by the bacteriological method (the degree of determination was 58.8%). The decrease of morbidity in shigellosis, observed at present in the Russian Federation, reflects a sharp drop in the production of milk and dairy products.
