目的为进一步了解浙江省宁海县传染病的发病动态,掌握居民中传染病的漏报情况,推算出比较接近实际的发病水平,为制订控制和消灭传染病的规划及防制措施提供依据。方法将全县划分为东、南、西、北、中5片,按分层随机整群抽样的原则进行回顾性入户调查。结果共对7个乡镇(街道)3120户10 276名居民进行法定传染病漏报入户回顾性调查,共调查到法定传染病9种149例,漏报38例,总漏报率为25.50%;甲乙类传染病无漏报,2010年甲乙类传染病报告发病率为241.35/10万,校正发病率为241.35/10万;丙类传染病漏报率为29.01%,2010年丙类传染病报告发病率为1066.57/10万,校正发病率为1502.42/10万。到医疗机构就诊的131例,漏报20例,漏报率15.27%;未就诊18例,漏报18例,漏报率100%。结论居民中法定传染病存在漏报现象,丙类传染病漏报率高,流动人口漏报率高于本地居民。
Objective To know more about the incidence of infectious diseases in Ninghai County of Zhejiang Province and master the omission of infectious diseases among residents, we can deduce the actual incidence and provide the basis for the planning and control of infectious diseases. Methods The whole county was divided into 5 parts in East, South, West, North and Central China. According to the principle of stratified random cluster sampling, retrospective household survey was conducted. Results A total of 10 276 residents in 3120 households in 7 townships (subdistricts) were investigated retrospectively. Of 149 cases of statutory communicable diseases, 149 cases were missed and 38 cases were missed. The total false negative rate was 25.50% ; Class A and B infectious diseases without omission, in 2010 the reported incidence of Class A and B infectious diseases was 241.35 / 100,000, the corrected incidence was 241.35 / 100,000; Class C infectious disease omission rate was 29.01%, Class C infectious diseases in 2010 Reported incidence of 1066.57 / 100,000, the corrected incidence of 1502.42 / 100,000. To the medical institutions of 131 cases, omission of 20 cases, the omission rate of 15.27%; 18 cases did not visit, omission in 18 cases, false negative rate of 100%. Conclusions The phenomenon of under-reporting of statutory communicable diseases in residents exists. The omission rate of C-type infectious diseases is high, and the false negative rate of floating population is higher than that of local residents.
