| Abstract: |
通过对128例病人的临床分析和流行病学调查，确认这是一起水型伤寒病爆发流行。发病始于1981年11月中旬，翌年元月下旬达到发病高峰，历时4月余，波及18个单位，患病率为590.1/10万。患者主要是青少年学生，占59.4%。
水源污染的原因是病人隔离治疗不当、粪便、污水未经处理排入枯水期河水，人们因饮用污染河水而发病。流行期间，从三处河水中分离到伤寒沙门氏菌与病人分离菌一致。
经过隔离收治病人，加强粪便管理、卫生宣传、饮用水消毒、菌苗注射及开放水闸加大河水流量等综合处理，流行终止。 |

| An outbreak of water-borne typhoid involving 128 units started in mid November, 1981 and ended in late Feb. 1982. The morbidity rate of the disease was 590.1/100,000.Most patients (59.4%) were children and adolescents. Water from a local river contaminated by excrements containing typhoid bacilli,which came from an open manure pit accounted for this outbreak. Data showed that all the patients had drunk polluted water from the said river.Laboratory results showed that the same type of typhoid bacillus was found from bed-side specimens and river water samples. Through isolation and treatment of the patients, proper management of night soil, disinfection of drinking water and immunization among healthy persons, the outbreak was brought under control. There after no new cases were found. |
