【摘要】：目的分析随州市发热伴血小板减少综合征(SFTS)的流行特征,探讨可能的传播途径,为SFTS防控提供科学依据。方法采用描述流行病学对2010年-2012年监测数据进行分析,对病例进行个案调查和病原学检测分析;选择有确诊病例的村进行传播媒介蜱密度调查和家畜总抗体水平调查及蜱的检测。结果随州市2010年-2012年共报告发热伴血小板减少综合征病例205例,其中确诊病例73例,死亡15例;呈散发状态,发病高峰在5月-7月;发病年龄为38岁~86岁(M=59岁);农民占98.63%,发病病例与蜱密度季节消长呈正相关。采集的91例住院病例新布尼亚病毒(SFTSV)核酸阳性率为54.94%;健康人的总抗体阳性率为3.82%;病例家宿主动物总抗体阳性率为63.15%,羊蜱的SFTSV核酸阳性率为17.65%。结论随州市为SFTS高发地区,发病主要在春夏季。提示重点防护人群为农民,蜱可能是传播媒介,做好宣传防护。
[Abstract]:Objective to analyze the epidemic characteristics of (SFTS) with fever and thrombocytopenia in Suizhou city, and to explore the possible transmission route, and to provide scientific basis for the prevention and control of SFTS. Methods descriptive epidemiology was used to analyze the surveillance data from 2010 to 2012, case investigation and etiology analysis. The density of vector ticks, the total antibody level of domestic animals and the detection of ticks were investigated in the villages with confirmed cases. Results 205 cases of fever with thrombocytopenia syndrome were reported in Suizhou City from 2010 to 2012, of which 73 cases were confirmed and 15 cases died. The incidence age was 38 years old to 86 years old (M 59 years old) and 98.63% to farmers. The incidence cases were positively correlated with the seasonal increase and decline of tick density. The positive rate of (SFTSV) nucleic acid in 91 hospitalized cases was 54.94, the total antibody positive rate of healthy persons was 3.82, the positive rate of total antibody of host animal was 63.15 and the positive rate of SFTSV nucleic acid of sheep tick was 17.655.The positive rate of NBV (SFTSV) nucleic acid was 54.94, that of healthy person was 3.82, that of host animal was 63.15 and that of sheep tick was 17.65. Conclusion Suizhou City is a high incidence area of SFTS and the disease mainly occurs in spring and summer. The results suggest that the key protection population is farmers, and tick may be the medium of communication, so as to do a good job in propaganda and protection.
