Several more genomes (n=19) have been released and this picture still holds true with a plausible (note, *lots* of caveats) median date of ~ early/mid-December.https://twitter.com/K_G_Andersen/status/1219280708188827649 …
It's clear from the epi data that human-to-human transmission does occur, however, we don't yet know how prevalent it is. Could be all cases (but 1) are H2H, could be a small subset. What we *can* conclude, is that people aren't being infected from a widespread animal reservoir.

All things considered, I'm leaning towards human-to-human transmission being the main mode (possibly exclusively by now), but more data is definitely needed.

I agree. For me this lack of diversity is one of the stronger pieces of evidence that it's primarily human-to-human. I have a hard time imagining a scenario having introductions over a longish time period that all come from incredibly closely related infections in animals.
