We investigated an outbreak of severe fever with thrombocytopenia syndrome (SFTS) that occurred during May and June 2010, to identify the mode of transmission. Contact with the index patient's blood was significantly associated with development of SFTS (P = .01, by the χ(2) test for linear trend); the frequency of contact with the index patient's blood increased the risk of SFTS in a dose-response manner (P = .03, by the χ(2) test for linear trend). We concluded that human-to-human transmission caused this cluster of cases.
我们调查了 2010 年 5 月至 6 月发生的严重发热伴血小板减少综合征 (SFTS) 暴发，以确定传播方式。与指数患者的血液接触与 SFTS 的发生显著相关（P =.01，线性趋势 χ(2)检验）；与指数患者的血液接触频率呈剂量反应方式增加 SFTS 的发病风险（P =.03，线性趋势 χ(2)检验）。我们得出结论，人与人之间的传播导致了这组病例。
