Read publication ↗Research question
What role did undocumented infections play in the early spread of SARS-CoV-2?
Geographic scope
China · early COVID-19 epidemic
Evidence base
Mobility-informed epidemiological modelling
Approach
A transmission model informed by population movement estimates the contribution of infections that were not documented at the time.
Why it matters
The findings demonstrate why observed case counts alone can be insufficient for understanding disease spread through connected cities.
