[Epidemiologic problems of gastrointestinal infections in children 0 to 2 years of age].

The analysis is presented of certain epidemiological problems based on a material including 774 cases of gastrointestinal infections hospitalized in two paediatric centres of the Province Paediatric Hospital in Warsaw in the years 1979/1981/1983. Faeces were examined obtained from children aged 0 to 24 months treated in hospital for diarrhoea. The material was presented in tables and was subjected to statistical analysis. The absolute number of the treated infants with diarrhoea increased successively in successive years of the study. No significant correlation was found in the frequency of hospitalizations of children from Warsaw and from the Province of Warsaw. The greatest group of children with diarrhoea were children in the first trimester of life, especially newborns. The greatest number of cases were treated in the first and second trimester of the calendar year. Most cases of diarrhoea were due to E. coli agglutinating with group A serum, and Klebsiella pneumoniae.
