SARS-CoV-2 variant sequences

The graph below presents the distribution of SARS-CoV-2 variant sequences over time, disaggregated by variants of concern (VOC), variants of interest (VOI), and variants under monitoring (VUM). Untracked variants are classified under the 'Other' category.

Note on potential biases

Please note, samples may be subject to bias resulting from:

  • geographical clustering in submission of sequences;
  • demographic clustering in submission of sequences; and,
  • mutation clustering arising from prioritised sequencing of samples with particular mutations
