ShowingImportancePrizesTopicZoonotic spillover
Cross-species transmission of a pathogen from an animal reservoir or intermediate host into humans, establishing human infection. Covers claims about spillover events, reservoirs, intermediate hosts, and the conditions enabling spillover, as the natural-emergence mechanism for a pathogen — for SARS-CoV-2 it marks the natural-origin side of the origin debate; it does not cover laboratory-origin or
No natural progenitor or intermediate animal host of SARS-CoV-2 has been identified
UnassessedNo current assessment. Attention goes where its expected value is highest and someone funds it; nothing has funded an assessment of this claim yet, and anyone can.constitution →empirical · derivedA factual claim that rests on inference from other evidence rather than direct observation.constitution →SARS-CoV-2 originimportance · notableImportance 0.50, from 0 to 1 · notable: a contested point in a live debate (also the default before judging).
