The first detection of Jingmen tick virus (JMTV) in humans in Türkiye, 2022

<i>Jingmen tick virus</i> (JMTV) is a single-stranded RNA virus transmitted to humans through tick bites and classified within the <i>Flaviviridae</i> family. It has been detected in various arthropods and mammals. JMTV causes an acute febrile illness with symptoms such as skin lesions, fatigue, headache, nausea, and vomiting; however, limited research exists on its clinical impact and pathogenesis in humans. This study aims to report the first detection and molecular characterization of JMTV in patients with Crimean-Congo Hemorrhagic Fever (CCHF) in Türkiye. During the 2022 outbreak, serum samples from 206 hospitalized CCHF-suspected patients were retrospectively analyzed. JMTV was identified in 3 (1.5%) cases using nested PCR. The nucleotide similarity within the three JMTV sequences was found to be between 98.0% and 99.0%. Phylogenetic analysis showed 82-98% similarity with previously identified JMTV isolates in Türkiye. This study presents the first detection and molecular characterization of JMTV in humans in Türkiye. Clinicians should consider JMTV in patients with a history of tick bites, especially in CCHF-endemic regions.
