Dear Editor,Severe fever with thrombocytopenia syndrome(SFTS)is an emerging tick-borne infectious disease caused by a novel bunyavirus called SFTS virus(SFTSV).It was initially identified in China in 2009(Yu et al.,2011).Since then,the number of reported SFTS cases has rapidly increased in China,South Korea,and Japan(Li,et al.,2018;Takahashi et al.,2014;Kim et al.,2018).Sporadic SFTS cases have also been identified in several other Asian countries,such as Vietnam,Pakistan,Myanmar,and Thailand(Takahashi et al.,2014;Tran et al.,2019;Li et al.,2021).This disease is recognized as a highly lethal viral hemorrhagic fever with a mortality rate ranging from 12%to 50%(Yu et al.,2011;Li et al.,2018;Takahashi et al.,2014;Kim et al.,2013).SFTS primarily spreads to humans through bites from ticks infected with SFTSV,with the Haemaphysalis longicornis tick acting as the predominant vector for SFTSV(Zhuang et al.,2018).
