In a bioRxiv preprint first posted October 21, 2020 (and later published in Molecular Biology and Evolution), Dellacour et al. (2020) report their studies of the spatial density of available SARS-CoV-2 genomes mapped in the Belgium epidemic.
Their phylodynamic analysis demonstrates real-time dispersion dynamics of SARS-CoV-2 lineages.
Among other things, their spatially-explicit phylogeographic analyses highlight that the national lockdown had a relatively low impact on both the lineage dispersal velocity and long-distance dispersal events within Belgium.
Simply put, the Belgian lockdowns show no statistical evidence of materially impacting pandemic dispersion.
