The Colorado Department of Health conducted intensive surveillance for waterborne diseases during the three-year period July 1, 1980-June 30, 1983. Eighteen outbreaks of waterborne illness were investigated. Outbreaks involved from 15 to 1,500 ill persons. Giardia lamblia was confirmed or suspected as the agent in nine outbreaks, rotavirus in one, and no agent could be identified in eight. Seventeen outbreaks occurred on surface-water systems; none of these had adequate chemical pretreatment and filtration. Investigation of water systems exhibiting positive coliform results during the first year detected no outbreaks. Activities important to effective surveillance included educational outreach programs to local health agencies, physicians and the public, and the designation of one individual to whom all water-related public complaints and health department inquiries were directed.
科罗拉多州卫生部在1980年7月1日至1983年6月30日的三年期间对水源性疾病进行了强化监测。对18起水源性疾病暴发进行了调查。暴发涉及15至1500名患病者。在9起暴发中，贾第鞭毛虫被确认为或疑似病原体，1起为轮状病毒，8起未发现病原体。17起暴发发生在地表水系统；这些系统均未进行充分的化学预处理和过滤。在第一年对大肠菌群检测呈阳性的水系统进行调查时未发现暴发情况。有效监测的重要活动包括针对当地卫生机构、医生和公众的教育推广项目，以及指定一名接收所有与水相关的公众投诉和卫生部门问询的人员。
