Molecular evolution and reassortment dynamics of Orthohantavirus hantanense revealed through longitudinal genomic surveillance in the Republic of Korea.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Orthohantavirus hantanense (HTNV), a major cause of hemorrhagic fever with renal syndrome (HFRS), remains a public health concern in East Asia. We investigated its evolutionary history, reassortment, and genetic diversity by analyzing 123 complete genomes from the Republic of Korea (1976-2023), comprising the most comprehensive dataset to date from this endemic region. Bayesian coalescent analyses estimated evolutionary rates ranging from 1.6 to 6.6 × 10⁻⁴ substitutions per site per year, with the Gn protein exhibiting the highest rate, suggesting gene-specific dynamics. Strong purifying selection (nonsynonymous/synonymous ratio < 0.1) was observed across all segments, reflecting substantial evolutionary constraints. Reassortment analysis revealed frequent segment exchanges, particularly involving the L segment, indicating segment compatibility differences and potential effects on viral fitness. Cline analyses identified a hybrid zone approximately 45 km wide in northern regions, highlighting the role of inter-lineage genetic exchange in enhancing viral diversity and adaptability. These findings clarify the evolution and phylogeography of HTNV and underscore the importance of ongoing genomic surveillance for identifying transmission hotspots, detecting emerging variants, and guiding targeted public health strategies to control endemic HFRS outbreaks effectively.
