目的了解宝鸡市2005～2007年病毒性脑炎监测系统运行效果,探讨流行性乙型脑炎(乙脑)流行病学特征及控制乙脑的策略和措施。方法建立病毒性脑炎监测系统,对病毒性脑炎病例进行专项监测,采用EPIData和Excel软件进行统计分析。结果病毒性脑炎与乙脑发病季节吻合,但发病年龄组构成不同。病毒性脑炎的漏诊率为23.76%。90d、180d随访,实际留有后遗症数是常规报告数的5.5倍,实际死亡数是报告死亡数的7倍。结论为了提高乙脑诊断及报告的准确性,应在乙脑流行季节开展病毒性脑炎监测及乙脑随访。
Objective To understand the operational effect of viral encephalitis surveillance system from 2005 to 2007 in Baoji City and to explore the epidemiological characteristics of Japanese encephalitis (JE) and the strategies and measures for controlling JE. Methods To establish a viral encephalitis surveillance system, and to monitor the viral encephalitis cases by using the software of EPIData and Excel. Results Viral encephalitis coincided with the onset of Japanese encephalitis, but with different age groups. The rate of missed diagnosis of viral encephalitis was 23.76%. 90d, 180d follow-up, the actual number of sequelae is 5.5 times the number of routine reports, the actual number of deaths is reported as 7 times the number of deaths. Conclusions In order to improve the accuracy of diagnosis and report of JE, viral encephalitis surveillance and JE follow-up should be conducted during the JE epidemic season.
