Geographic distribution of Yezo virus (YEZV) detection in ticks from Russia. Red diamonds indicate sampling locations of YEZV-positive Ixodes persulcatus ticks. A) Distribution across Russia. YEZV prevalence (%) and sampling year are indicated adjacent to symbols. B) Distribution within the Kemerovo region. Samples of isolates 143 (GenBank accession nos. PV770292, PX898221, and PX904396), 24-4 (accession nos. PV770294, PX898220, and PX904395), 6-1 (accession nos. PV770295 and PX898217), 6-4 (accession nos. PV770296 and PX898218), and 6-5 (accession nos. PV770297, PX898219, and PX904394) were derived from ticks collected in location 1. The sample of isolate 165 (accession nos. PV770293, PX898222, and PX904397) was derived from a tick collected in location 2. C) Distribution within the Khabarovsk region. Samples of isolates 560 (accession nos. PV770287, PX898225, and PX904391), 576 (accession nos. PV770288, PX898226, and PX904392), 649 (accession nos. PV770289, PX898227, and PX904390), and 662 (accession nos. PV770290, PX898228, and PX904393) were derived from ticks collected in location 3.
