Fig. 1: S result and WGS typed variant found in community surveillance.

A Number of S-gene target failure (SGTF) and non-SGTF positive tests over time (n = 986,974). B Whole-genome sequencing (WGS) typed variant found in national genome surveillance of community testing samples in the Netherlands (n = 17,907). Boxes indicate the Delta-Omicron BA.1 cohort (dotted line) and Omicron BA.1-BA.2 cohort (dot-dashed line).
