Figure 3. Monitoring and quantifying variant spread using ID Solutions Revolution tests (N = 193,256), France, December 6, 2021–February 28, 2022. A) Raw proportion of the test outcomes. B) Estimated frequency of A0B9C0D1 relative to the sum of A0B9C0D1 and A0B9C1D0 tests in France. Raw occurrence data from panel A is stratified by region in Appendix 1 Figure ). Test designations indicate the absence of a mutation by a 0 and its presence by 1 (9 means the mutation was not tested); mutations are the same as in Figure 2 and D is S:417N; A0B9C0D1 mostly corresponds to Omicron variant, A0B9C1D0 to Delta variant and A0B9C1D1 to Omicron-Delta coinfection.
