> IC analysts assess that a natural origin and a laboratoryassociated incident are both plausible hypotheses for
how SARS-CoV-2 first infected humans. Analysts,
however, disagree on which is more likely, or whether
an assessment can be made at all, given the lack of
diagnosticity of the available information. Most
agencies are unable to make higher than low confidence
assessments for these reasons, and confidence levels are
tempered by plausible arguments for the opposing
hypothesis. For these hypotheses, IC analysts consider
an exposure that occurs during animal sampling activity
that supports biological research to be a laboratoryassociated incident and not natural contact.
