Fig. 1: Genomic epidemiology of SARS-CoV-2 in Nigeria.

A Epicurve of SARS-CoV-2 cases in Nigeria in Nigeria and genomes produced assembled during the first three waves with the y-axis transformed to a log-scale. B Time-varying sampling fraction of genomes produced in this study per new cases. C Geographic distribution of sequences generated in the current study. The map of Nigeria shows the number of genomes from states across the country as region colour and marker size display lineages per state. Maps © Mapbox (www.mapbox.com/about/maps) and © OpenStreetMap (www.openstreetmap.org/about). D Lineage frequency profile for the study period. The frequency of PANGO lineages across the country over a period of 80 weeks. Lineages that are not VOCs or VOIs, or that do not appear more than three times over the course of the pandemic, are grouped as “others”. E Human mobility data from Google for retail shops, pharmacies, parks, public transport, workplaces, and residential activity places from January 2020 to November 2021, as compared to the pre-pandemic baseline (January to February 2021).
