摘　　要：目的调查六安市健康人群和宿主动物SFTSV的感染率,探讨六安市存在自然疫源地的可能性,为制定防控策略提供依据。方法选取六安市病例较多的3个县,按照1∶1配比的方法确定4个病例村和4个对照村,调查测健康人群和宿主动物SFTSV血清流行病学情况,并比较不同地区间感染率有无差异,同时调查蜱等吸血媒介的种类和带毒率。结果共采集血清标本371份,SFTSV总抗体阳性111份,阳性率为29.92%,其中健康人群166份标本,检出阳性14份,阳性率8.43%;宿主动物205份标本,检出阳性97份,阳性率47.37%。不同县间、病例村和对照村间阳性率以及不同家畜的宿主动物SFTSV感染率差异有统计学意义。结论六安市部分地区的健康人群和宿主动物均有较高的SFTSV的感染率,属SFTS的流行区域,因而需加强监测报告、诊断识别和临床救治等能力。Objective To investigate the infection rate of severe fever with thrombocytopenia syndrome virus （SFISV） among the healthy crowds and host animals of Liu＇an. Also, to explore the possibility of the existence of natural foci, so as to provide basis for the prevention and control. Methods 3 counties which with frequent cases was selected. 4 case- and 4 control- villages were matched to investigate the serum epidemiological characteristic of SFTSV. The differences of the infection rates was compared between different regions. We also investigated the types and poisoned rates of ticks and other blood-sucking media. Results 371 serum samples were collected, and 111 samples were antibody positive, which accounted for 29.92%. 166 samples were from healthy people, and 14 samples were antibody positive, which accounted for 8.43%. 205 samples were from animals, and 97 samples were antibody positive, which accounted for 47.37%. The differences of positive rate between different counties and villages were significant. There was significant statistical difference between the host animals according to the infection rate of SFI＇SV. Conclusion The infection rates of SFPSV were high and Lu＇an belonged to the epidemic area of SFPSV. It was necessary to strengthen the monitoring report, diagnosis recognition and clinical treatment ability.
