- Virology: An emerging tick-borne disease Severe fever with thrombocytopenia syndrome (SFTS), a tick-borne infectious disease caused by a novel phlebovirus, is a growing global health concern. The main symptoms are high fever, low platelet and white blood cell levels, and gastrointestinal problems. The disease was first identified in China in 2009, and several SFTS epidemics have occurred in East Asia, with mortality rates of between 6 and 27 per cent. Researchers in South Korea led by Young Ki Choi at Chungbuk National University, Cheongju, review the latest research into SFTS virus and disease, including transmission, genetic diversity, epidemiology, pathology and clinical features, and pandemic potential. Animal models are helping researchers understand the virus and disease and develop treatments and vaccines. An emerging infectious disease first identified in central China in 2009, severe fever with thrombocytopenia syndrome (SFTS) was found to be caused by a novel phlebovirus. Since SFTSV was first identified, epidemics have occurred in several East Asian countries. With the escalating incidence of SFTS and the rapid, worldwide spread of SFTSV vector, it is clear this virus has pandemic potential and presents an impending global public health threat. In this review, we concisely summarize the latest findings regarding SFTSV, including vector and virus transmission, genotype diversity and epidemiology, probable pathogenic mechanism, and clinical presentation of human SFTS. Ticks most likely transmit SFTSV to animals including humans; however, human-to-human transmission has been reported. The majority of arbovirus transmission cycle includes vertebrate hosts, and potential reservoirs include a variety of both domestic and wild animals. Reports of the seroprevalence of SFTSV in both wild and domestic animals raises the probability that domestic animals act as amplifying hosts for the virus. Major clinical manifestation of human SFTS infection is high fever, thrombocytopenia, leukocytopenia, gastrointestinal symptoms, and a high case-fatality rate. Several animal models were developed to further understand the pathogenesis of the virus and aid in the discovery of therapeutics and preventive measures.
