Metagenomic surveillance reveals extensive viral diversity and regional clustering in ticks, highlighting the need for targeted vector control.

To characterize the diversity and geographic distribution of tick-borne viruses across distinct ecological regions.
Collected 2,867 ticks in 2021 across four provinces in China: Inner Mongolia, Hebei, Hunan, and Hainan.
Performed metagenomic sequencing and phylogenetic analysis to profile tick-borne viromes and evaluate regional genetic lineages.
Identified eleven tick-borne viruses belonging to Phenuiviridae, Nairoviridae, Chuviridae, Rhabdoviridae, and unclassified virus groups.
Demonstrated significant variation in viral composition driven by tick species and geography, showing distinct regional phylogenetic clustering.
Detected Lihan tick virus in Hunan and Bole tick virus 4 in argasid ticks from Inner Mongolia for the first time, alongside a novel severe fever with thrombocytopenia syndrome virus lineage in Shijiazhuang.
