介水传染病 Water-borne communicable diseases 通过饮用或接触受病原体污染的水而传播的疾 病,又称水性传染病。 大致有40多种传染病是通过介水而传播的。 常见的介水传染病有霍乱、伤寒、副伤寒、痢 疾、病毒性肝炎等肠道传染病以及血吸虫、贾 第鞭毛虫、隐孢子虫等寄生虫病和钩端螺旋体 病

2. Pathogenic Microorganisms Associated with Waterborne disease 主要有三类: ① Bacteria细菌,如大肠杆菌、伤寒杆菌、霍乱 弧菌、痢疾杆菌等。 ② Viruses病毒,如甲型肝炎病毒、脊髓灰质炎 病毒、柯萨奇病毒和腺病毒等。 ③ Protozoa原虫,如隐孢子虫、贾第氏虫、溶 组织阿米巴原虫、血吸虫等。它们主要来自人 粪便、生活污水、医院以及畜牧屠宰、皮革和 食品工业等废水
