COVID-19 Viral Genome Analysis Pipeline
Enabled by data from   gisaid-logo

This website provides analyses and tools for exploring accruing mutations in hCoV-19 (SARS-CoV-2) geographically and over time, with an emphasis on the Spike protein, using data from GISAID.

The SARS-CoV-2 sequence data used for these analyses was updated from GISAID on Apr 30, 2021.

With the ever growing database of sequences in GISAID, sometimes the web connection times out before the analysis is complete. If you have this problem, please check "email results" and an email with a link will be sent to you when the job is complete.

The analyses provided are based on a trimmed full length SARS-CoV-2 alignment containing 810,565 sequences:
sequence names and ID numbers used for full-length analyses,
or on a Spike alignment containing 1,062,910 sequences:
sequence names and ID numbers used for spike-only analyses.

The details of the analyses are described in:
Tracking changes in SARS-CoV-2 Spike: evidence that D614G increases infectivity of the COVID-19 virus.
