Nextstrain SARS-CoV-2 resources

Around the world, people are sequencing SARS-CoV-2. The Nextstrain team analyzes these data on a global and continental level. More specific analysis are often provided by groups around the world. This page lists all SARS-CoV-2 analysis that use nextstrain that we are aware of. In addition to exploring SARS-CoV-2 evolution in finished analyses, you can use our new Nextclade tool to compare your sequences to the SARS-CoV-2 reference sequence, assign them to clades, and see where they fall on a the SARS-CoV-2 tree.

All SARS-CoV-2 Builds

This section is an index of public Nextstrain builds (datasets) for SARS-CoV-2, organized by geography. Some of these builds are maintained by the nextstrain team and others are maintained by independent research groups. (See here for more information on what a build is, and see this tutorial for a walkthrough of running your own phylogenetic analysis of SARS-CoV-2 data!) If you know of a build not listed here, please let us know! Please note that inclusion on this list does not indicate an endorsement by the Nextstrain team.

All SARS-CoV-2 situation reports

We have been writing interactive situation reports using Nextstrain Narratives to communicate how COVID-19 is moving around the world and spreading locally. These are kindly translated into a number of different languages by volunteers and Google-provided translators — click on any language below to see the list of situation reports available.
