[Comparative importance of different transmission factors in the spread of acute intestinal infections]

The authors generalized literature data on a comparative epidemiological significance of individual ways of transmission in the spread of escherichiasis, shigelloses, salmonelloses and cholera. Resistance of the corresponding causative agents to the factors of external environment and the action of gastric juice were considered. Data on concentrations of different enteropathogenic agents in the feces of patients, convalescents and healthy carriers were compared with the observations on doses causing the disease in man. On the basis of analysis a conclusion was drawn on a different significance of water, food and domestic ways of infection in the spread of various etiological forms of acute intestinal infections.
