摘　　要：目的 分析2011-2015年信阳市发热伴血小板减少综合征（SFTS）病例流行病学特征。方法 采用描述流行病学方法对2011-2015年信阳市SFTS监测资料进行分析。利用PHGIS1.7.0软件绘制SFTS病例县区分布图,各种率差异的比较使用χ^2检验。结果 2011-2015年信阳市共报告SFTS病例3 373例,发病率波动在7.22/10万-19.80/10万;死亡49例,病死率为1.45%。病例集中在商城县、光山县和浉河区,占总病例数的70.29%。4-10月发病较多,占97.18%;5-7月为发病高峰,9月出现次高峰。病例年龄平均61岁,主要集中在40-79岁年龄组,占89.42%。女性发病率16.33/10万,高于男性的10.08/10万（χ^2=190.341,P〈0.001）。农民发病3 241例,占96.09%。2011-2015年信阳市SFTS病例中新布尼亚病毒的检测阳性率为61.09%,其中60-99岁最高为68.07%,不同年龄组病例检测阳性率差异有统计学意义（χ^2=72.666,P〈0.001）。结论 信阳市SFTS报告发病数呈逐年上升趋势,发病存在明显的地区差异和季节性,人群普遍易感,农村中老年女性高发。Objective To analysis the epidemiological characteristics of severe fever with thrombocytopenia syndrome （SFTS） in Xinyang City,2011 -2015. Methods Descriptive epidemiology was used to analyze the characteristics of SFTS in Xinyang City,2011 - 2015. PHGIS1.7.0 software was used to map the regional distribution of SFTS. The chi - square test was used to analyze the difference of rates. Results There were 3373 cases of SFTS reported in Xinyang City during 2011 - 2015. The incidence rates fluctuated from 7.22 per 100000 to 19.80 per 100000. 49 patients died, and the fatality rate was 1.45%. Cases concentrated in Shangcheng County, Guangshan County and Shihe County, accounting for 97. 18%. Cases mainly occurred between April and October. Incidence peaked first from May to July and then in September. The average patient age was 61 years,and 89.42% of patients were between 40 and 79. SFTS was less prevalent in men （ 10.08 per 100000） than in women （ 16.33 per 100000） , and the difference in prevalence was statistically significant （χ^2= 190. 341 ,P 〈 0. 001 ）. The vast majority of patients with SFTS were farmers （3241 patients ,96.09% ）. The positive rate for nucleic acid of new bunyavirus was 61.09% in Xinyang City during 2011 -2015 ,and the positive rate was the highest in 60 -99 -year- old groups,which was 68.07%. There were significant differences among different age groups （χ^2= 72. 666,P 〈 0. 001 ）. Conclusion The number of reported SFTS cases shows a rising trend in Xinyang City during 2011 -2015. SFTS shows obviously regional and seasonal characteristics. People are generally susceptible and elderly female farmers are at high risk of the disease.
