Generation-time distortion is an emergent property of epidemic control

Generation-time reshaping emerges as a fundamental population-level feature of interventions that reduce individual infectiousness, and ignoring it can misestimate effectiveness by 100% under realistic settings.

• Why it matters: Many analyses treat generation times as stationary, but this assumption is more fragile than recognized, risking biased estimates of intervention impact and control stability.
• What they did: The authors build a universal microscopic representation spanning intervention mechanisms that lower individual-level infectiousness, then constrain its topology to match mechanisms and derive generation-time predictions.
• The result: Neglecting generation-time reshaping can under- or over-estimate intervention effectiveness and disease control-lability by 100%, and even a stringent intervention can yield no estimated transmissibility difference.
