Molecular Epidemiology and Seroepidemiology of Oz Virus Infection in Ticks and Wild Boars in Ibaraki Prefecture, Japan.

ABSTRACT: Oz virus (OZV), an emerging negative-sense single-stranded RNA virus classified under the family Orthomyxoviridae and genus Thogotovirus, was first isolated from Amblyomma testudinarium ticks in Ehime Prefecture, Japan, in 2013. Moreover, a single fatal case in an elderly individual, suspected to be associated with OZV infection, was reported in Ibaraki Prefecture in 2023. Given these circumstances, this study was conducted to investigate the molecular epidemiology and seroepidemiology of OZV in Ibaraki Prefecture, Japan. From April to November 2023, a total of 2430 ticks were collected at 19 sites. The OZV RNA was detected in one A. testudinarium nymph. Additionally, among 934 wild boar serum samples collected between 2019 and 2023, one sample tested positive f
