Severe fever with thrombocytopenia syndrome virus (SFTSV) is a novel phlebovirus that was identified to be the etiological pathogen of the emerging infectious disease, severe fever with thrombocytopenia syndrome (SFTS). SFTSV could be transmitted through tick bite. Transmission of SFTSV among humans has also been reported mainly through direct blood contact. In July 2014, a cluster of six suspected SFTS cases occurred in Shandong Province, China. In this cluster, both symptomatic and asymptomatic persons were included. By analyzing the clinical data and results of laboratory tests, and conducting the epidemiological interviews with the cases and their families, risk factors responsible for the transmission were evaluated. The findings suggested that SFTSV transmission among humans may cause asymptomatic infection via personal contact without blood exposure.
发热伴血小板减少综合征病毒(SFTSV)是一种新型白蛉病毒,被确定为新发传染病发热伴血小板减少综合征(SFTS)的病原体。SFTSV可通过蜱叮咬传播。据报道,SFTSV在人与人之间的传播主要也是通过直接血液接触。2014年7月,中国山东省发生了一起6例疑似SFTS病例的聚集性疫情。该聚集性疫情中包括有症状和无症状的人员。通过分析临床资料和实验室检测结果,并对病例及其家属进行流行病学访谈,评估了导致传播的危险因素。研究结果表明,SFTSV在人与人之间传播可能通过无血液暴露的人际接触导致无症状感染。
