B.1.1.7 sequences from India and Canada now represented alongside countries previously with B.1.1.7 sequences on GISAID @art_poon ImageImage
Updated sequence counts and reports on volume of passengers leaving London in October, including the report of a B.1.1.7 case identified in Colorado yesterday nytimes.com/2020/12/29/hea…. @MOUGK @EvolveDotZoo Image
Updated rolling 7-day average of counts and frequency per country, again thanks to @viralverity! ImageImage

Latest new variant report for 2020-12-31 now online.
pangolin assigned 4,632 B.1.1.7 sequences from 21 countries across the world. In addition to countries previously reported, there are now B.1.1.7 sequences from USA (2), Switzerland (1) and Germany (1).
@arambaut @viralverity ImageImage
New sequences reported from the UK, Denmark, the Netherlands and India, in addition to the new sequences from the USA, Switzerland and Germany. Image
The frequency plot shows the proportion of sequences from each country that are lineage B.1.1.7. For countries with low numbers of sequences reported, the frequency is likely not representative of the SARS-CoV-2 circulating in the community. Image

Latest SARS-CoV-2 new variant report now available at cov-lineages.org/global_report.…. Data pulled from GISAID on 2020-12-29 11:23 GMT and pangolin run on the entire dataset. There are now 4,323 B.1.1.7 genomes on GISAID, from 16 countries across the world. @arambaut @viralverity ImageImage
Although most of these sequences are from the UK, it's important to bear in mind the differences in sequencing efforts/ data sharing across the world, which will bias the data we see. Image
We have updated sequence counts overlayed on aggregate data of passengers leaving London in October, capturing true movement of people.
