Abstract: Objective To analyze intervals between illness onset and confirmation of severe fever with thrombocytopenia syndrome (SFTS) cases and related factors which will provide scientific information for its precise control and prevention. Methods Data on SFTS cases from 2011 to 2016 were obtained from China Information System for Diseases Control and Prevention. The intervals from illness onset to confirmation of SFTS cases in different genders, age groups, occupations, seasons, and provinces were summarized and compared using SPSS 20.0 software. Results A total of 5 360 SFTS cases were reported in China from 2011 to 2016 and the median interval from illness onset to confirmation of these cases was 9 d. Intervals from illness onset to confirmation of SFTS cases were significantly different from year to year and the maximum median of the interval of SFTS in 2014. Intervals between illness onset and confirmation of SFTS cases from different provinces were also significantly different, the intervals of Hubei province were the longest and the intervals of Zhejiang province were the shortest. Conclusion Although there were differences in the intervals of SFTS cases from different years, provinces and individual cases, the intervals were nevertheless very long. Appropriate interventions should be implemented to shorten the intervals for the control and prevention of SFTS.

摘要: 目的 分析发热伴血小板减少综合征(SFTS)病例发病至确诊时间间隔及其分布特征,为我国SFTS的精准防控提供科学依据。方法 从中国疾病预防控制信息系统收集2011-2016年SFTS病例信息,利用SPSS 20.0软件对不同年度、性别、年龄组、职业、季节及省份SFTS病例发病至确诊时间间隔进行描述性分析和统计学分析。结果 全国共报告5 360例SFTS确诊病例,所有病例发病至确诊时间间隔的中位数为9 d,四分位数间距为22 d。不同年份SFTS病例发病至确诊时间间隔差异有统计学意义(H=896.088,P=0.000)。2014年病例发病至确诊时间间隔中位数最长,主要分布在60 d内,而其他年份主要分布在20 d内。不同省份病例发病至确诊时间间隔差异有统计学意义(H=221.404,P=0.000)。湖北省病例发病至确诊时间间隔最长,浙江省最短。结论 不同年度、不同省份和不同人群SFTS病例发病至确诊时间间隔存在差异,但均较长,需要采取针对性措施缩短该时间间隔。
