- Below the threshold (R < 1, subcritical) activity decays geometrically toward extinction; at the threshold (R = 1, critical) it persists at a steady level; above it (R > 1, supercritical) it grows or sustains without continued external driving.
This sourceRigorous definition of R₀ as the expected number of secondary cases per typical infected individual, the dominant eigenvalue of the next-generation operator, with the unity threshold separating subcritical decay from supercritical growth.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
