[BDSP. Notice produite par INIST-CNRS tpBR0xpC. Diffusion soumise à autorisation]. The relation between sporadic gastroenteritis and recreational swimming was examined in a cohort of 2,811 people in Melbourne, Australia, over a 15-month period (September 1997-February 1999). Data from a prospective community-based study of gastroenteritis were used for a Poisson analysis of temporality between reported swimming (in public or private pools/spas and in marine or freshwater settings) and a highly credible gastroenteritis (HCG) event. Overall, HCG events were more likely in participants who had swum in a public pool/spa (incidence rate ratio (IRR)=1.25,95% confidence interval (CI) : 1.10,1.42 ; P=0.001) or river/lake/dam (IRR=1.77,95% CI : 1.13,2.79 ; P=0.014) during the previous week or had swum in a public pool/spa (IRR=1.29,95% CI : 1.13,1.46 ; P
