目的了解2004—2013年北京市海淀区流行性脑脊髓膜炎(流脑)流行病学特征,为预防控制流脑提供依据。方法对流脑病例进行描述流行病学分析。结果 2004—2013年海淀区共报告75例流脑病例,死亡14例,发病水平呈下降趋势,外来人口发病率和死亡率远远高于该市人口(χ2=74.314,P<0.001)。病例分布在22个地区,均为散发;3—5月为高发季节,占病例总数的67.00%(50/75);男性比女性多,性别比为3.17∶1(57∶18);15~30岁是高发年龄,占病例总数的46.67%(35/75);发病以民工和学生为主,占病例总数的65.33%(49/75)。结论 2004—2013年海淀区流脑发病水平呈持续下降趋势,并维持在极低水平,要继续做好流脑疫苗常规接种和外来务工人员流脑疫苗接种,并加强流脑病例、健康人群流脑病原学监测。
Objective To understand the epidemiological characteristics of epidemic cerebrospinal meningitis (ICH) in Haidian District of Beijing from 2004 to 2013 and provide evidence for prevention and control of ECM. Methods Descriptive epidemiological analysis of meningioma cases. Results A total of 75 cases of meningoencephalitis were reported in Haidian District from 2004 to 2013, with 14 deaths. The morbidity and mortality of migrants were much lower than that of the city (χ2 = 74.314, P <0.001). The cases were distributed in 22 districts, with high incidence in March-May, accounting for 67.00% (50/75) of the total number of cases; more males than females, the sex ratio was 3.17:1 (57:18) The age of 30 was high incidence, accounting for 46.67% (35/75) of the total number of cases. The incidence was mainly migrant workers and students, accounting for 65.33% (49/75) of the total number of cases. Conclusion The incidence of meningitis in Haidian District continued to decline from 2004 to 2013 and remained at a very low level. It is necessary to continue routine vaccination of meningococcal vaccine and meningococcal vaccination of migrant workers, and to strengthen the meningococcal disease and healthy population flow Encephalopathy monitoring.
