A cross-sectional telephone survey was conducted in Denmark throughout 2009 to determine the incidence of acute gastrointestinal illness (AGI). Using the Danish population register, a random population sample stratified by gender and age groups was selected and mobile or landline phone numbers found. Representative numbers of interviews were performed by gender, age group and month. A recently proposed international case definition of AGI, including cases with diarrhoea and/or vomiting in a 4-week recall period, was used. A total of 1853 individuals were included and 206 (11.1%) fulfilled the case definition; 78% reported diarrhoea. This corresponds to an overall standardized incidence rate of 1.4 (95% CI 1.2-1.6) episodes of AGI per person-year. The incidence rate was generally higher in the younger age groups; only being 2.3, 1.9 and 0.80 per person-year in the 0-9, 10-39 and >= 40 years age groups, respectively. The incidence rate estimates were considerably higher when calculated from shorter recall periods.
