洪灾前后抚顺市新抚区几种腹泻病发病情况比较分析

A STUDY ON THE ATTACK OF SEVERAL DIARRHOEAS IN XINFU REGION OF FUSHUN CITY AROUND THE FLOOD.

本文通过对新抚区灾前、灾后两年菌痢发病率的预测值与实际值的显著性检验，发现二者无差异（Ｐ＞０．０５），灾后菌痢发病率虽然下降，但发病高峰后移，集中在灾后半个月内；对菌痢和肠炎在两年间的发病进行显著性检验，发现差异显著（Ｐ＜０．０５）；灾后肠炎的报告发病数成倍增加，再结合漏诊率调查，则实际发病更多。由于灾后自来水浊度超标，致使人们普遍饮用地下水，但检验结果显示地下水的细菌总数和大肠菌群数均不同程度地超标。结果说明洪灾确实对人民的身体健康形成威胁，但防疫工作的落实情况可直接影响疾病的发生和流行。

e studied the expected and practical value of attack rate of bacillary during two years around the flood,and compared these values which we abstained after the flood with the values we had before the flood.We found that there no obvious difference between them(P>005);though the attack rate of bacillary and enteritis during the two years around the flood,an obvious difference between them were found(P<005).Reports of the attack rate of enteritis were double in the creased,in fact,the rate were even higher than that reported because there were still some cases which were not reported.Tap water got dirty after the flood,so people turned to drink groundwater,however tests indicate that the total number of bacili and coliform in groundwater are also higher than the stand and value.As a result,it threaten the health of the crowd.But the state of antiepidemic work can affect the out break and spread of a disease directly.
