Severe fever with thrombocytopenia syndrome virus infection attributed to cat contact: A case report in Beijing, China

Shuo Zhang et al. Virol Sin. 2024 Jun.

Abstract

  1. •

    SFTSV is detected in host-seeking ticks in rural–urban fringe areas in Beijing.

  2. •

    SFTSV RNA, IgM, and neutralizing antibodies are detected in stray cats in Beijing.

  3. •

    Multiple SFTSV genotypes naturally circulate within ticks in Beijing's urban zones.

Detection of SFTSV in urbanized areas in Beijing. A The location where the patient acquired SFTSV infection, indicated by red triangle. B Five sites (S1 to S5) from where tick and cat samples were collected. Cats were living in site 1 (S1). Host-seeking ticks were collected by dragging fabric over vegetation at five sites. Blood-sucking ticks were collected from goats at site 1 (S1) and site 5 (S5). The red triangle indicates the location of the patient. The dotted box indicates the area size of the field survey (200 ​m∗200 ​m). C The positive rate of SFTSV in host-seeking or blood-sucking ticks. Host-seeking ticks were pooled (4–5 ticks per pool) for the detection of SFTSV RNA. The blood-sucking ticks collected from goats were individually tested. D Phylogenetic tree was conducted based on nucleotide sequence of nearly complete S segment (1743 bp) of SFTSV with Neighbor-Joining method and 1000 bootstrap replicate using MEGA X software. Corresponding nucleotide sequence of Heartland virus (GenBank accession number JX005842) was used as outgroup. Sequences obtained in this study were indicated as black triangle, with GenBank accession numbers of OR871539 (patient), OR871540 (cat), OR871541 and OR871542 (tick).
