  1. The table presents the progression of the Sj,t index across different CoMix survey waves for various age groups, listed in the first 9 rows of each panel. It also includes the stringency index50 of NPIs, detailing specific measures affecting schools, workplaces, travel, and public transport. Average daily contact rates for the overall population, split by adults and minors, are provided, along with the mean Rt values for each wave, estimated from positive PCR tests78. This comprehensive data offers insights into the evolving dynamics of SARS-CoV-2 transmission across demographic segments over time.
