Journal AWWA - Risk Assessment of Waterborne Coxsackievirus AWWA杂志-水传播柯萨奇病毒的风险评估
发布日期: 2003-07-01
柯萨奇病毒是最常见的非病毒 在生活污水和污染环境中发现的肠道病毒 地表水、地下水和饮用水。 这些病毒可导致呕吐、发烧、头痛、皮疹和腹泻 腹泻并导致无菌性脑膜炎等严重后果, 心肌炎、呼吸系统疾病、脑炎和胰岛素依赖性疾病 糖尿病。以前的研究调查 水样中的肠道病毒将肠道病毒视为 并没有关注特定的病毒。本文介绍 评估潜在公众风险的风险评估方法 与饮用水和娱乐相关的健康影响 被柯萨奇病毒污染的水域。 根据人体剂量反应建立的指数模型 研究被用来描述柯萨奇B型病毒的传染性 并估计每日和每年的感染风险、发病率和死亡率。 柯萨奇病毒在环境中的稳定性 水处理及其与一系列严重疾病的关系 强调保持可靠和有效的 废水和饮用水的处理。其他研究正在进行中 在供水中发生柯萨奇病毒时需要 病毒检测侧重于识别特定病毒,而不是 病毒群。由此产生的数据将导致一个更完整的数据库 这有助于水处理的决策过程 以及流域保护计划。包括83个参考文献、表格和图表。
Coxsackieviruses are the most common nonpolio enteroviruses found in domestic wastewater and in contaminated surface water, groundwater, and drinking water. These viruses can cause vomiting, fever, headache, rash, and diarrhea and result in such serious outcomes as aseptic meningitis, myocarditis, respiratory illness, encephalitis, and insulindependent diabetes mellitus. Previous research investigating enteroviruses in water samples treated the enteroviruses as a group and did not focus on specific viruses. This article describes a risk assessment approach to evaluate the potential public health effects associated with drinking water and recreational waters contaminated by coxsackievirus. An exponential model developed from human dose-response studies was used to describe the infectivity of coxsackievirus type B and estimate daily and yearly risks of infection, morbidity, and mortality. The stability of coxsackievirus in the environment, its resistance to water treatment, and its association with a range of serious illnesses underscore the importance of maintaining reliable and effective treatment of wastewater and drinking water. Additional research is needed on the occurrence of coxsackievirus in water supplies, with viral testing focusing on identification of specific viruses rather than viral groups. The resulting data will lead to a more complete database that can assist in the decision-making process for water treatment and watershed protection programs. Includes 83 references, tables, figures.
