2020-05-22: The algorithm for handling missing bases (N) was changed, this may cause some minor differences in the statistics.
This page shows primer and probe sequence match for several publically available real-time PCR assays. To view data, choose a virus from the first menu (currently only SARS-CoV-2 is supported), then choose an assay from the second menu. For details, see the About page. We thank GISAID for making sequence data available for this analysis. See Acknowledgements.
Assays indicated with a * has one or more mismatches that likely arise from primer design rather by virus mutation, they are excluded from this chart. The individual assay page shows these mismatches.
