SARS-CoV-2 Phylogeny (Nextstrain)

Phylogenetic evolution of SARS-CoV-2 in Europe including Czech sequences — an interactive tree of variants and their geographic spread.

This dashboard opens Nextstrain — the standard for real-time phylogenomic pathogen surveillance, developed by the Bedford Lab (Fred Hutch / WHO).

What Nextstrain shows

  • Phylogenetic tree — evolutionary relationships between SARS-CoV-2 sequences
  • Geographic spread — an animation of how variants spread across countries
  • Timeline — when each variant emerged and when it dominated
  • Czech sequences — the Czech Republic contributes sequences via GISAID

Available Nextstrain builds

BuildDescription
ncov/gisaid/europeEurope — GISAID sequences (includes CZ)
ncov/open/globalGlobal open-data build
ncov/open/europeEurope — open data
Open Nextstrain — SARS-CoV-2 Europe

Local Nextstrain build (for your own sequences)

To build from your own or local sequences, a Nextstrain/Augur Docker container is available in docker-compose.yml (profile nextstrain):

docker compose --profile nextstrain run augur --help

Required input files:

  • nextstrain/data/sequences.fasta — FASTA sequences from GISAID/ENA
  • nextstrain/data/metadata.tsv — metadata (date, source, location)
