目的 了解中国(未包括中国香港特别行政区、澳门特别行政区和台湾) 2013-2015年＜ 15岁儿童吉兰-巴雷综合征(Guillain-Barré syndrome,GBS) 流行特征及空间聚集性.方法 采用描述流行病学方法分析2013-2015年＜ 15岁儿童通过急性弛缓性麻痹病例监测信息报告管理系统报告的GBS病例数据,使用时空聚集性探索方法分析GBS可能的聚集区域.结果2013-2015年中国共报告GBS 2 803例,报告发病率为0. 41 /10万(标化: 0. 42 /10万); 男、女性报告发病率分别为0. 47 /10万、0. 35 /10万; 春季、秋季和冬季报告病例分别占22. 51％、26. 26％ 和26. 51％; GBS病例存在4个时空聚集的县级区域.结论 中国2013-2015年GBS发病存在时空聚集性.“,”Objective To determine the epidemiological characteristics of Guillain-Barré syndrome(GBS) among children under 15 years old,and to identify temporal-spatial clusters of GBS in China(excluding Chinese Hong Kong Special Administrative Region,Macao Special Administrative Region, and Taiwan),2013-2015. Methods Descriptive methods were used to analyze GBS cases ＜ 15 years old in 2013-2015. A retrospective,temporal-spatial analysis was used to detect possible clusters in China. Results A total of 2 803 GBS cases were reported,for an incidence of 0. 41 per 100 000 population(adjusted: 0. 42 per 100 000 population). The incidence of GBS was 0. 47 per 100 000 population among males and 0. 35 per 100 000 population among females; 22. 51％,26. 26％ and 26. 51％ of GBS cases occurred in spring,autumn and winter,respectively. County-level temporal-spatial clusters of GBS were detected in 4 areas. Conclusions GBS showed temporal-spatial clustering in China during 2013-2015.
