| 1982年12月上旬至1983年1月下旬,锦州市南票矿区发生一次以腹泻、腹鸣、腹胀、腹痛为主要症状的腹泻流行。病例分布全矿区八个住宅区,共发生7,369例,发病率14.25%,以一个供水系统的三个住宅区发病率为最高(31.39%、27.39%、22.39%),其余住宅区发病率仅为5.44%。男性发病高于女性,以青壮年发病最高,儿童和老人发病最低。其流行原因是因两个水源被污染先在三个住宅区爆发,饮用污染水居民发病率为32.58%,同住宅区内饮用自家铁管并非污染水居民发病率为11.59%。其余住宅为生活接触传播,家庭续发率为15.39%,呼吸道传播途径可排除。 |

| From December 1982 to February 1983, an outbreak of adult diarrhea occurred in a coal mine area nearby Jin-Zhou. The disease was characterized by a very short incubation period with a cho-lera-like clinical manifestations:very fast prevalent, sudden onset, severe choleraic watery diarrhea and vomiting with no or low fever. The patients involved were mostly adults, although all age ranges could be affected. No antibiotics were effective, but it was self-limited, having a duration of 4 to 7 days. The total 7369 cases were found in eight residential areas of the coal mine. The incidence was estimated as 14.25%, but it fluctuated from 31.39%, 27.39% and 22.39% (the three residencial areas with a common water supply) to the lowest incidence of 5.44% in rest areas.The water supply for those with high incidences was proved to be polluted and the incidence could reach to the peak of 32.58%. Nevertheless, the inhabitants in the same community using individual self-supplied water (deep water) had a much lower incidence(11.59%). The consecutive familial incidence was also investigated(15.39%) and the resperatory route of spreading of the disease was definitely excluded. |
