Around the world, people are sequencing and sharing SARS-CoV-2 genomic data. The Nextstrain team analyzes these data on a global and continental level. More specific analyses are often performed by groups around the world. This page lists a sample of such analyses. In addition to exploring SARS-CoV-2 evolution in finished analyses, you can use Nextclade 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.
- Latest global SARS-CoV-2 analysis (GISAID data)Jump to our globally-subsampled SARS-CoV-2 dataset which is updated daily using data from GISAID. We also maintain additional analyses to focus subsampling on different geographic regions and different time periods. These include analyses that focus on the previous 6 months for Africa, Asia, Europe, North America, Oceania and South America, as well as analyses that focus on the entire pandemic for Africa, Asia, Europe, North America, Oceania and South America.
- Latest global SARS-CoV-2 analysis (open data)Jump to our globally-subsampled SARS-CoV-2 dataset which is updated daily using open data from GenBank. Additional analyses that focus subsampling on different geographic regions and different time periods include analyses that focus on the previous 6 months for Africa, Asia, Europe, North America, Oceania and South America, as well as analyses that focus on the entire pandemic for Africa, Asia, Europe, North America, Oceania and South America.

This section is an index of public Nextstrain datasets for SARS-CoV-2, organized by geography. Some of these datasets are maintained by the Nextstrain team and others are maintained by independent research groups. If you know of a dataset not listed here, please let us know! Please note that inclusion on this list does not indicate an endorsement by the Nextstrain team.
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.
