继1993年密尔沃基隐孢子虫病爆发后，我们检查了爆发期间八个来源的数据。尽管监测高峰在时间上有显著的对应关系，但最及时的数据涉及使用这样的系统，即与公共卫生方案有密切联系的人员认识到提供信息的重要性，尽管与疫情有关的工作量有限。在调查过程中，监测系统，可以很容易地与实验室数据，灵活地添加新的变量，并证明低基线变异性是最有用的。地理位置固定的疗养院居民作为一个理想的人口与非混杂暴露。使用替代的发病率测量方法可以在实验室确诊之前引发有价值的公共卫生反应，并有助于降低与疫情相关的总发病率。本报告介绍了这些监测方法的相对优势和劣势，在社区范围内的水传播疾病检测和疫情决策中的应用。
Following the 1993 Milwaukee cryptosporidiosis outbreak, we examined data from eight sources available during the time of the outbreak. Although there was a remarkable temporal correspondence of surveillance peaks, the most timely data involved use of systems in which personnel with existing close ties to public health programmes perceived the importance of providing information despite workload constraints associated with an outbreak. During the investigation, surveillance systems which could be easily linked with laboratory data, were flexible in adding new variables, and which demonstrated low baseline variability were most useful. Geographically fixed nursing home residents served as an ideal population with non-confounded exposures. Use of surrogate measurements of morbidity can trigger worthwhile public health responses in advance of laboratory-confirmed diagnosis and help reduce total morbidity associated with an outbreak. This report describes the relative strengths and weaknesses of these surveillance methods for community-wide waterborne illness detection and their application in outbreak decision making.
