郑州城区2004～2005年鼠疫监测分析

STUDY ON RISK FACTORS OF PLAGUE SPREAD IN ZHENGZHOU DURING 2004-2005

[目的]调查分析郑州城区目前鼠疫传播潜在的危险因素,为预防控制措施的制定提供参考。[方法]2004～2005年连续两年每单月开展鼠密度、种群构成、染蚤率调查,并采集鼠血进行鼠F1抗体检测。采用问卷调查方式,了解临床医务人员对鼠疫防治知识的掌握情况。[结果]两年监测资料显示:城区鼠密度为1.78%;捕获的鼠中,褐家鼠占71.88%,为优势鼠种;鼠染蚤率为43.75%;总蚤指数为1.78;蚤种均为印鼠客蚤;鼠血清学检测均为阴性。鼠疫防治知识问卷调查,正确回答率为39%。[结论]城区为可接受性鼠疫非流行区。但由于多数医务人员不熟悉鼠疫防治知识,存在人间鼠疫输入病例被误诊、漏诊的可能;城区居于交通枢纽的地理位置,又增加了鼠疫远距离传播的危险性。应引起重视。

[Objective] ITo investigate the potential risk factors of plague dissemination in Zhengzhou at present, and to provide reference for formulating prevention and control measures. [Methods] In every odd number month from 2004 to 2005, the mouse density, structure of animal species, investigation on flea infection rate of rats were developed, and blood samples of rats were gathered to test the plague F1 antibody simultaneously. Questionnaire survey was used to observe the master situation of anti-plague knowledge of the clinical medical personnel. [ Results] Two years＇ monitoring materials demonstrated that moose density in city proper was 1.78%; Among the captured mice, Rattus non, egicus accounted for 71.88%, plants for the superiority mouse; flea infection rate of rats was 43.75% ; the total flea index was 1.78 ; the flea was Xenopsylla cheopis; the serology examinations of rats were all negative. And the correct rate about the anti-plague knowledge through questionnaire survey was 39%. [Conclusions] The city is the acceptable plague non-popular area. But because most medical personnel are not familiar with anti-plague knOwledge, there is the possibility that misdiagnosiS, missed diagnosis about human plague imported cases; and the city occupies transportation hub of geographical position, increasing the risk of plague long-range transmission, which should be attach more attention to.
