This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Rapid assessment of which animal viruses may be capable of infecting humans is currently intractable, but would allow their prioritization for further investigation and pandemic preparedness. We developed machine learning algorithms that identify candidate zoonoses using evolutionary signals of host range encoded in viral genomes. This reduces lists of hundreds of viruses with uncertain human infectivity to tractable numbers for prioritized research, generalizes to virus families excluded from model training, can distinguish high risk viruses within families that contain a minority of zoonotic species, and could have identified the exceptional risk of SARS-CoV-2 prior to its emergence. Genome-based risk assessment allows identification of high-risk viruses immediately upon discovery, increasing both the feasibility and likelihood of downstream virological and ecological characterization and allowing for evidence-driven virus surveillance.
