Recipients on this medium are inferred from channel membership, not per-message addressing.

So I think most parsimonious would be `Malaysia/MKAK-CL-2020-6430|EPI_ISL_416886|2020-02-04` -> `WA1` -> `WH04` -> `Wuhan-Hu-1`

In context

A single line often inverts meaning once you see what it answers, so neighbouring messages are always shown.

    Can you just summarise where the root should fall? I didn't follow all that chain.
  2. 2020-12-06 12:11 Kristian G. Andersen open
    WA1
  3. 2020-12-06 12:27 Andrew Rambaut open
    And by WA1 we mean a haplotype identical to WA1 that was in Wuhan before the 15th January

    Curious though that the Malaysian one is one SNP closer to RmYN02 than all the others. So possibly that one (but the January cases in Malaysia were Chinese nationals visiting)

    (but all in Wuhan)

    Would it be worth trying to simulate a WA1 with a date in the beginning of December and run beast?

    Given we see identical genomes spaced 6 weeks apart, I don't think we need to use imputed dates - just enforce WA1 to be an outgroup
