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 Feb 3, 2023.
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.
