Owing to anthropogenic climate change and the distribution of tick hosts, tick-borne human and animal diseases are an increasing global health concern. Also, increased outdoor human activities have increased the prevalence and distribution of tick-borne viruses, causing public health issues. This study aims to effective surveillance for novel tick-borne viruses and contribute to establishing preventive strategies against inflow viruses in Asia. To analyze tick-borne pathogens and predict circulating viruses, tick virome analysis was conducted, between 2022 and 2023, on fed ticks from 33 different animals across Asian countries. A total of 261 ticks including Amblyomma, Haemphysalis, Hyalomma, Rhipicephalus, and Ixodes ticks. Next-generation sequencing (NGS) identified 46 species of DNA and RNA viruses from 17 families, with the highest number of virome genes observed for Phenuiviridae, Poxviridae and Herpesviridae. Guanarito mammarenavirus, Orf virus and Beiji nairovirus were key identified among these. These results suggest the high possibility of the transmission of tick-borne viruses across several animals and humans.
