OBJECTIVE: The objective of the present study was to describe the epidemiology of reportable enteric illness in Ontario’s Waterloo region, including comparing calculated incidence rates with published rates, and adjusting for under-reporting to determine the number of community cases, where published data were available.METHODS: Descriptive analyses were performed on reportable disease data for 13 enteric diseases collected in the Waterloo region from 1990 to 2004. Poisson and negative binomial regression analyses were used to investigate differences in incidence rates among age, sex, the 15 years of data and seasons. Disease-specific incidence rates were calculated and compared with the literature, where possible. Under-reporting ratios from the literature were applied to estimate the number of cases of campylobacteriosis, nontyphoidal salmonellosis and verotoxigenic Escherichia coli infection at the community level.RESULTS: Over the study period, the average annual age- and sex-adjusted incidence rates per 100,000 population were highest for campylobacteriosis (49.69 cases), followed by giardiasis (31.87 cases) and nontyphoidal salmonellosis (25.97 cases). The incidence of most enteric illnesses peaked in the summer. The highest incidence occurred in young children, followed by adults in their 20s. Diarrhea (85.4%) was the most frequently reported symptom, food (57.4%) was the most commonly reported probable source, and home (41.7%) and travel (37.0%) were the two most frequently reported risk settings.CONCLUSIONS: Enteric illness was a significant health burden in the Waterloo region from 1990 to 2004. Because reportable disease data are subject to under-reporting, it is likely that the true burden is greater than estimated in the present study.

1990 年至 2004 年 C-EnterNet 试点站点 - 安大略省滑铁卢地区的肠道疾病流行病学。

目的：本研究的目的是描述安大略滑铁卢地区可报告肠道疾病的流行病学，包括将计算的发病率与公布的发病率进行比较，并调整漏报以确定社区病例的数量，其中已公布数据可用.方法：对 1990 年至 2004 年滑铁卢地区收集的 13 种肠道疾病的可报告疾病数据进行描述性分析。使用泊松和负二项回归分析来调查不同年龄、性别、15 年数据和季节。在可能的情况下，计算特定疾病的发病率并与文献进行比较。应用文献中的漏报率来估计弯曲杆菌病的病例数，大肠杆菌结果：在研究期间，弯曲杆菌病（49.69 例）的年龄和性别调整后年均发病率最高，其次是贾第虫病（31.87 例）和非伤寒沙门氏菌病（25.97 例） . 大多数肠道疾病的发病高峰在夏季。发病率最高的是幼儿，其次是 20 多岁的成年人。腹泻 (85.4%) 是最常报告的症状，食物 (57.4%) 是最常报告的可能来源，家 (41.7%) 和旅行 (37.0%) 是两个最常报告的风险环境。 结论：肠道疾病从 1990 年到 2004 年，滑铁卢地区的健康负担很重。
