Objective To understand the epidemiological characteristics of meningococcal meningitis in China (except Hong Kong, Macao and Taiwan areas) and provide evidence for the disease prevention and control. Methods Descriptive epidemiological analysis was conduct on the incidence data of meningococcal meningitis from October 1, 2009 to September 30, 2010 in China, which were collected from national disease reporting information system. Results The incidence of meningococcal meningitis declined by 50. 98% in 2009-2010 season compared with that in 2008-2009 season. The cases were mainly distributed m 5 provinces (45. 10% ). The cases in age group 0-14 years accounted for 62.61% of the total, and the incidence in young children aged ≤2 years was highest. Conclusion It is still necessary to continue the surveillance of acute encephalitis/meningitis syndrome in the context of consecutive decline of reporting meningococcal meningitis incidence in China and strengthen the primary vaccination of meningococcal meningitis in children less than 2 years old. Chemoprophylaxis of sulfamido or quinolones is not recommended%目的 分析中国(未包括香港、澳门特别行政区和台湾地区)流行性脑脊髓膜炎(流脑)流行病学特征,为流脑预防控制提供参考依据.方法 运用描述流行病学方法分析2009-2010年(2009年10月1日至2010年9月30日)全国法定传染病报告系统流脑疫情.结果 2009 -2010年与2008 - 2009年相比,发病率降低50.98％.病例相对集中于5个省,其发病数占全国病例总数的45.10％;0～ 14岁病例与病例总数的62.61％,其中＜2岁婴幼儿发病率最高.结论 在近年来全国流脑报告发病水平持续下降的形势下,在监测点应持续开展急性脑炎脑膜炎症候群监测;应加强＜2岁儿童的流腩基础免疫工作;不推荐磺胺类和喹诺酮类药物作为流脑的预防性药物.
