Timeline of COVID-19 cases and sequencing in Québec up to June 1. A Comparison of confirmed cases (grey) reported by public health authorities and high-quality sequences used in this study (blue) distributed by collection date. *Official lockdown included stay home orders and closure of schools and daycares. **Except schools in the city of Montreal. Timeline and control measures are from [15, 16]. Sample dates of sequences can be slightly offset from official daily case count due to reporting lags. B Age distribution of sequenced cases (mean and range shown). C Variation in viral epidemiological dynamics as estimated by Tajima’s D. Boxplots represent 99 resampled estimates of Tajima’s D from random resamplings of 20 genome sequences for each 2-week time period. Tajima’s D values are only estimated for PANGO lineages with at least 20 sequences in a given time period
