Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick‑borne zoonosis in East Asia, yet the contribution of animals to virus maintenance and spillover remains incompletely characterized. This review examines current evidence of SFTS virus (SFTSV) infection across domestic livestock, companion animals, wildlife, and captive species, focusing on host range, geographic distribution, diagnostics, and reports of viral RNA and virus isolation. Available data indicate that SFTSV exposure and infection occur across a broad range of animal hosts, supporting a multi-host ecological framework rather than a simple single-reservoir interpretation. Domestic ruminants frequently exhibit high seroprevalence and may function as sentinels of enzootic activity, while occasional virus isolation from cattle demonstrates that viable virus can be recovered from naturally infected livestock, although this does not establish reservoir or amplification competence. Companion animals are considered a potential interface for interspecies transmission, as some studies have documented severe clinical disease, high viral loads, and cat-associated human transmission events supported by varying levels of epidemiological and genomic evidence. Studies in wildlife further document exposure and natural infection across diverse taxa, although their specific roles in viral maintenance remain unresolved. Interpretation of these findings depends heavily on the diagnostic modality: serology primarily indicates prior exposure, RNA detection supports current or recent infection, and virus isolation demonstrates that viable virus was present in the sampled material. Integrating animal infection data within an ecological framework reveals major knowledge gaps related to reservoir competence, infectious shedding, phylogenetic connections among animal, tick, and human cases, and implications for prevention. The review underscores the need for One Health surveillance that incorporates clinical data from companion animals and applies evidence‑based interpretation to improve recognition of animal–human interfaces associated with potential spillover risk.

Bandavirus dabieense, a single-stranded RNA virus, is the causative agent of severe fever with thrombocytopenia syndrome (SFTS), a disease associated with high fatality rates. Early and accurate diagnosis is essential for improving clinical outcomes, particularly given the limited therapeutic options and high mortality rates associated with SFTS. However, while highly sensitive, conventional diagnostic methods such as PCR and qRT-PCR require specialized laboratory facilities and trained personnel, making them impractical for rapid detection in resource-limited settings. To address these challenges, we developed a rapid and highly sensitive assay for Bandavirus dabieense detection by integrating reverse transcription loop-mediated isothermal amplification (RT-LAMP) with CRISPR/Cas12a technology. LAMP primers and guide RNA sequences were designed to target the L gene, ensuring broad detection across viral genotypes. The optimized assay demonstrated a detection limit of 5 RNA copies per reaction, showing more sensitivity than qRT-PCR, and exhibited 100% concordance with qRT-PCR results in clinical samples. Given its speed, accuracy, and field applicability, this LAMP-CRISPR/Cas12a-based assay represents a promising diagnostic tool for early SFTSV detection, particularly in resource-constrained environments where conventional molecular diagnostics are not readily available.

Abstract
PDF
- Severe fever with thrombocytopenia syndrome (SFTS) is a life-threatening viral zoonosis. The causative agent of this disease is the Dabie bandavirus, which is usually known as the SFTS virus (SFTSV). Although the role of vertebrates in SFTSV transmission to humans remains uncertain, some reports have suggested that dogs could potentially transmit SFTSV to humans. Consequently, preventive measures against SFTSV in dogs are urgently needed. In the present study, dogs were immunized three times at two-week intervals with formaldehyde-inactivated SFTSV with two types of adjuvants. SFTSV (KCD46) was injected into all dogs two weeks after the final immunization. Control dogs showed viremia from 2 to 4 days post infection (dpi), and displayed white pulp atrophy in the spleen, along with a high level of terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling assay (TUNEL) positive area. However, the inactivated SFTSV vaccine groups exhibited rare pathological changes and significantly reduced TUNEL positive areas in the spleen. Furthermore, SFTSV viral loads were not detected at any of the tested dpi. Our results indicate that both adjuvants can be safely used in combination with an inactivated SFTSV formulation to induce strong neutralizing antibodies. Inactivated SFTSV vaccines effectively prevent pathogenicity and viremia in dogs infected with SFTSV. In conclusion, our study highlighted the potential of inactivated SFTSV vaccination for SFTSV control in dogs.

Abstract
PDF
- Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne emerging infectious disease caused by the SFTS virus (SFTSV) and is a threat to public health due to its high fatality rate. However, details on tick-to-human transmission of SFTSV are limited. In this study, we determined the wholegenome sequence of a South Korean SFTSV strain (CUKJJ01), compared it to those of other recent human SFTSV isolates, and identified the genetic variations and relationships among the SFTSV strains. The genome of CUK-JJ01 was consistent with the genome of other members of the genus Phlebovirus, including the large (L), medium (M), and small (S) segments of 6368, 3378, and 1744 nucleotides, respectively. Based on amino acid sequences of the M and S segments, which are used to distinguish the six SFTSV genotypes, CUK-JJ01 was classified as genotype B. Segment analysis revealed that the L, M, and S segments were 97.49%, 97.18%, and 97.94% similar to those of KAJNH2/2013/ Korea, ZJZHSH-FDE/2012/China, and KADGH/2013/Korea, respectively. Currently, only few studies on SFTSV have been conducted in Korean population and most were limited to serological analysis. Although the present study has limitations in terms of number of sample analyzed, the findings may serve as basis to understand the transmission and spread of SFTSV, as well as for the development of diagnostic and detection methods for viral recombinants by comparing the whole genome sequence of SFTSV isolates from South Korea and that of foreign isolates.
