Abstract

Significance: With changes in land use and increased urbanization, the frequency with which pathogens jump species barriers to emerge in new hosts is expected to rise. Knowing which viruses may be more likely to become transmissible among humans, as opposed to only generating dead-end spillover infections, would be of considerable benefit to pandemic planning. Using multivariate modeling and multimodel inference, we sought to both identify and quantify those biological features of viruses that best determine interhuman transmissibility. This analysis revealed that chronic, nonsegmented, non–vector-borne, nonenveloped viruses with low host mortality had the highest likelihood of being transmissible among humans whereas genomic features had little predictive power. Our analysis therefore reveals that multiple virological features determine the likelihood of successful emergence.

  • Cross-species transmission results from a complex interplay between pathogen characteristics, the original host's infection, behavior, and ecology, pathogen shedding and survival in the environment, human exposure, and human susceptibility.

    “Cross-species transmission results from a complex interplay between the characteristics of the pathogen (2, 10–12): the original host’s infection, behavior, and ecology; how the pathogen is shed into and survives in the environment; how humans are exposed to the pathogen; and how susceptible those humans are to infection (4, 12–16).”

    From Impacts of biodiversity and biodiversity loss on zoonotic diseases (2021) · cites this paper as [2]

    The Significance and Discussion sections identify viral traits associated with human-to-human transmission and acknowledge ecological factors and barriers to host adaptation. They do not establish the claimed interplay involving the original host’s behavior, environmental shedding and survival, human exposure, and human susceptibility; the paper’s main analysis concerns onward transmission after spillover.

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.
