A Study of Seroprevalence and Rates of Asymptomatic Viremia of Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV) among Chinese Blood Donors

摘要

BackgroundSFTSV, an emerging tick-borne pathogen that can cause fatal severe fever with thrombocytopenia syndrome (SFTS), was first identified in China in 2009. Limited evidence suggests that SFTSV can be transmitted between humans via blood contact raising concerns over transfusion safety. A study of donor samples from three Chinese blood centers was conducted to investigate the seroprevalence and rate of SFTSV viremia among Chinese blood donors.
