Spatio-temporal dynamics of Hendra virus in Pteropus bats in Australia reveals high evolutionary diversity linked with spillover

Open access

Preprint — published as 10.1038/s41564-025-02254-7

Abstract

Hendra virus (HeV) was first discovered in 1994 in Australia, following an outbreak of respiratory and neurological disease in horses and humans. Limited genomic data on HeV has hindered a comprehensive understanding of HeV’s evolutionary dynamics. We conducted extensive spatiotemporal sampling and whole-genome sequencing of HeV-positive samples from bats and horses and genomic analyses revealed four distinct clades and additional cryptic clades. Each clade extended over a large spatial area, with strains from different clades co-occurring within a single roost on the same day and over multiple consecutive years. This absence of spatiotemporal genotypic structuring suggests that viral shedding events are not driven by the introduction of a single lineage into a susceptible population and then strain evolution through population level immune pressure. These findings provide crucial insights into how bats generate and maintain their extraordinary viral diversity, with direct implications for zoonotic disease emergence and pandemic threats.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
