发热伴血小板减少综合征死亡危险因素及预警模型研究进展

发热伴血小板减少综合征（severe fever with thrombocytopenia syndrome, SFTS）是由发热伴血小板减少综合征病毒感染引起的一种蜱媒传染病。自该病发现以来，我国已有数千人患病，病死率可高达30%，目前发病范围仍在持续扩大。为更深入地了解该病临床特征，本文就近年来SFTS死亡危险因素及预警模型相关研究进展加以综述，以期为SFTS的临床治疗及预后判断提供新的思路。

Research progress on death risk factors and early warning model of severe fever with thrombocytopenia syndrome

Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne infectious disease caused by severe fever with thrombocytopenia syndrome virus. Since its discovery, the disease has sickened thousands of people in China and the fatality rate can reach up to 30%. At present, the scope of the disease is still expanding. In order to understand the clinical characteristics of the disease in more details, this paper reviews the research progress of death risk factors and early warning model with respect to SFTS, so as to provide new ideas for the clinical treatment and prognosis judgement of SFTS.
