A retrospective, cross-sectional telephone survey (n=2090) was conducted in Ontario, Canada, between May 2005 and April 2006, to determine the burden of acute gastrointestinal illness in the population. The 4-week prevalence was 8.56% (95% CI 7.36-9.76); in households with more than one resident, 35% of cases reported someone else in their household had similar symptoms at the same time. The annual adjusted incidence rate was 1.17 (95% CI 0.99-1.35) episodes per person-year, with higher rates in females, rural residents, and in the winter and spring. Health care was sought by 22% of cases, of which 33% were asked to provide a stool sample. Interestingly, 2.2% of cases who did not visit a health-care provider reported self-administering antibiotics. Overall, acute gastrointestinal illness appears to pose a significant burden in the Ontario population. Further research into the specific aetiologies and risk factors is now needed to better target intervention strategies.
2005年5月至2006年4月期间，在加拿大安大略省开展了一项回顾性横断面电话调查（n = 2090），以确定该人群中急性胃肠道疾病的负担。4周患病率为8.56%（95%置信区间7.36 - 9.76）；在有多名居民的家庭中，35%的病例报告称其家庭中的其他人同时出现了类似症状。年度调整发病率为每人每年1.17次（95%置信区间0.99 - 1.35），女性、农村居民以及冬季和春季的发病率较高。22%的病例寻求了医疗护理，其中33%被要求提供粪便样本。有趣的是，2.2%未就诊的病例报告自行服用了抗生素。总体而言，急性胃肠道疾病似乎给安大略省人群带来了重大负担。现在需要进一步研究具体病因和风险因素，以便更好地制定干预策略。
