Severe fever with thrombocytopenia syndrome virus
摘要:
Severe fever with thrombocytopenia syndrome virus (SFTSV) is a highly pathogenic tick-borne bunyavirus that can cause severe viral hemorrhagic fever (SFTS), with a case fatality rate of up to 30%. SFTSV was first identified in 2010, which is primarily transmitted through tick bites but can also be transmitted to humans by sick people or infected cats and dogs. The main clinical manifestations of SFTS include high fever, gastrointestinal symptoms, thrombocytopenia, and leukopenia, with severe cases potentially resulting in death due to multi-organ failure. In 2017, the World Health Organization (WHO) listed SFTS as a priority disease with the potential to cause a public health emergency of international concern. SFTS cases have been reported in China, East Asia, and Southeast Asia, making it an important public health issue. In China, SFTS cases have been reported in 27 provincesincluding Henan, Hubei, Shandong, Anhui, Liaoning, Zhejiang, and Jiangsu. Additionally, SFTS cases have been identified in East and Southeast Asian countries such as South Korea, Japan, Vietnam, Myanmar, Thailand, and Pakistan. This review summarizes the epidemiology and pathogenesis of SFTSV, providing a basis for better understanding the mechanisms of immune evasion and developing effective countermeasures. © 2025 Editorial Office of Modern Preventive Medicine.
