Tracking diversity and spread of SARS-CoV-2 in Nextstrain
Available data on Jan 26
Early genomes differed by only a few mutations, suggesting very recent emergence
→ the closest to "real-time" we have experienced so far...

The genome accumulates about two mutations a month...
Diversified into multiple global variants. Groups 20A/B/C have taken over.
