Abstract
SFTSV is an emerging tick-borne virus causing hemorrhagic fever with a case fatality rate (CFR) that can reach up to 27%. With endemic infection in East Asia and the recent spread of the vector tick to more than 20 states in the United States, the SFTSV outbreak is a globally growing public health concern. However, there is currently no targeted antiviral therapy or licensed vaccine against SFTSV. Considering the age-dependent SFTS pathogenesis and disease outcome, a sophisticated vaccine development approach is required to safeguard the elderly population from lethal SFTSV infection. Given the recent emergence of SFTSV, the establishment of animal models to study immunogenicity and protection from SFTS symptoms has only occurred recently. The latest research efforts have applied diverse vaccine development approaches-including live-attenuated vaccine, DNA vaccine, whole inactivated virus vaccine, viral vector vaccine, protein subunit vaccine, and mRNA vaccine-in the quest to develop a safe and effective vaccine against SFTSV. This review aims to outline the current progress in SFTSV vaccine development and suggest future directions to enhance the safety and efficacy of these vaccines, ensuring their suitability for clinical application.

Abstract
Background Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne disease resulted from SFTSV. It is found in Japan, South Korea, Central, and Eastern China. With the increasing prevalence of SFTS and the rapid spread of the SFTS virus (SFTSV) vector, it is obvious that this virus has pandemic potential and poses an imminent public health concern. Case Presentation We depict SFTS in a child from Anhui Province and conduct a review of all reported pediatric cases in China, which is an endemic area for SFTS. From 2011 to 2021, ten SFTS pediatric cases confirmed by RT-PCR were reported, with no child dying. Although SFTS cases in adolescents and children are uncommon, the reported literature showed that clinical symptoms in adolescents and children were milder than in adults. Conclusion To better understand this emerging disease, we described the clinical and epidemiological attributes of SFTS. We suggest that the possibility of SFTSV infection in children with seasonal and virus-related acute febrile diseases should be considered in major endemic areas.

Abstract
Background Severe fever with thrombocytopenia syndrome (SFTS) is an infectious disease caused by a bunyaviridae virus. Its main clinical manifestation is fever with thrombocytopenia, which may be accompanied by other clinical symptoms. Here, we report a patient diagnosed with SFTS using metagenomic next‑generation sequencing (mNGS). Case Presentation A 56-year-old female patient was hospitalized with intermittent diarrhea and fever. She visited a local clinic for treatment, but instead of improving, the symptoms progressed to unconsciousness. Diagnosis Using mNGS, we isolated the bunyaviridae virus and several other pathogens from the patient’s blood samples to confirm the diagnosis. Interventions The patient was treated with symptomatic and supportive therapy, including intravenous human γ-globulin (20 g/d), platelet transfusion, platelet elevation (subcutaneous injection of recombinant human thrombopoietin, 15,000 IU), white blood cell elevation (subcutaneous injection of recombinant human granulocyte colony-stimulating factor, 200 ug, qd); and antibiotic (cefoperazone sodium and tazobactam sodium, 2 g, q8h), antiviral (ganciclovir, 250 mg, q12h), and antifungal therapy (voriconazole for injection, 0.2 g, q12h). After ten days of treatment, the patient’s condition gradually improved. Conclusion Compared to traditional detection methods, mNGS has many advantages. It can quickly identify the pathogen when the patient’s clinical manifestations are complex and difficult to diagnose, resulting in the formulation of an effective treatment.

Abstract
To define the clinical manifestations and laboratory characteristics of pediatric severe fever with thrombocytopenia syndrome (SFTS) case caused by a novel bunyavirus. we retrospectively analyzed a pediatric case of viral SFTS in a 13 year old successfully managed and confirmed to be due to the novel bunyavirus now referred to as Huaiyangshan virus. A literature review of related cases was performed.Our pediatric case was a 13.3-year-old middle school student no underlying disease. Major clinical features included a fever with chills, headache, and dizziness. The patient's epidemiology showed he had close contact with his grandfather who had a confirmed, novel bunyavirus infection. Symptomatic theraphy were given at admission. The patient's temperature and platelet count returned to normal by days 7 and 10, respectively, and he was discharged from the hospital with an improved condition. A literature search was performed using "severe fever with thrombocytopenia syndrome" and "bunyavirus" as keywords, but few relevant reports were found. Novel bunyavirus infection can be transmitted through close contact. Confirmed cases should be kept in isolation. Clinical manifestations were characterized by aspecific symptoms, such as fever and chills. In some cases, platelet counts may remain normal in the early phase of the disease, and fever may not present throughout the entire illness period. Thus, misdiagnosis is possible. Surveillance and vigorous follow-up should be carried out in children with tick bites or in close contact with an index patient in high-risk areas during peak season.

Abstract
Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease and elderly people living in rural areas have the greatest risk of infection. We report the first pediatric case of SFTS in Korea and the clinical characteristics and disease progression in children. A 10-year-old child from Chonnam province visited the hospital with myalgia and a history of fever over the previous 8 days. Her father noticed a tick on her head and removed it before fever developed. Because the symptoms continued, her father consulted the community health center and SFTS virus was detected both from the tick (Haemaphysalis longicornis) and the patient's blood. On hospitalization, fever and severe myalgia were improved and no gastrointestinal and hemorrhagic symptoms were observed. The patient was successfully treated with a combination of steroids, IVIG, and ribavirin. In this report, a pediatric case of SFTS presents a mild clinical course but close attention must be paid to the screening of children with mild symptoms consisting of SFTS.

Abstract
Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne infectious disease caused by the SFTS virus (SFTSV), a novel phlebovirus reported to be endemic to China in 2011. In Japan, the first SFTS patient was identified during the autumn of 2012; since then, over 100 SFTS patients have been reported. The SFTSV has been identified throughout Japan over the past two years; however, SFTS patients are specifically localized to western Japan. The clinical symptoms of SFTS include fever, thrombocytopenia, leukocytopenia, gastrointestinal symptoms, and various other symptoms, including muscular symptoms, neurological abnormalities, and coagulopathy. SFTS is often accompanied by hemophagocytic syndrome. The histopathological findings are characterized by necrotizing lymphadenitis, with infiltration of the virus-infected cells to the local lymph nodes. Pathophysiological analyses of SFTS include studies regarding the kinetics of cytokine production and immune responses in patients with SFTS and in SFTSV-infection animal models. This article aimed to survey the history of SFTS in Japan and to review the clinical, epidemiological, and virological aspects of SFTS and SFTSV infection.

Abstract
Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel bunyavirus (SFTS virus, SFTSV). At present there is still no specific antiviral treatment for SFTSV; To understand which cells support SFTSV life cycle and whether SFTSV infection activates host innate immunity, four different cell lines (Vero, Hela, Huh7.5.1, and Huh7.0) were infected with SFTSV. Intracellular/extracellular viral RNA and expression of IFNα, and IFNß were detected by real-time RT- PCR following infection. To confirm the role of non-structural protein (NSs) of SFTSV in exogenous IFNα-induced Jak/STAT signaling, p-STAT1 (Western Blot), ISRE activity (Luciferase assay) and ISG expression (real-time PCR) were examined following IFNα stimulation in the presence or absence of over-expression of NSs in Hela cells. Our study showed that all the four cell lines supported SFTSV life cycle and SFTSV activated host innate immunity to produce type I IFNs in Hela cells but not in Huh7.0, Huh7.5.1 or Vero cells. NSs inhibited exogenous IFNα-induced Jak/STAT signaling as shown by decreased p-STAT1 level, suppressed ISRE activity and down-regulated ISG expression. Suppression of the exogenous Type I IFN-induced Jak/STAT signaling by NSs might be one of the mechanisms of SFTSV to evade host immune surveillance.

Abstract
This report describes a pediatric case of severe fever with thrombocytopenia syndrome (SFTS), which is an emerging disease that is caused by a novel bunyavirus. Interestingly, the previously reported SFTS cases typically involved elderly patients, while our case involved a 5-year-old child from Zhejiang Province, China. In this report, we describe our investigation of the clinical and epidemiological characteristics of this case, to improve our understanding of this emerging disease. Our principle finding was that the present case's clinical symptoms were milder than those that have been reported in adult cases of SFTS. Therefore, we recommend more careful screening of pediatric patients who present with mild symptoms that are consistent with SFTS.
