Super interesting journal article hit my desk a few minutes ago, fresh off the press:
https://www.nejm.org/doi/full/10.1056/NEJMoa2001316?query=RP
Seems, at least at the time of the writing, that average transmission rate (Ro) was 2.2, meaning for every person infected, it was transmitted to 2.2 people. This isnt TERRIBLE and was before measures were put in place to contain the virus - so its likely lower now. Im hearing that streets are empty in heavily impacted areas - all signs (that I have seen) is that China is taking this one very seriously.
Average incubation period is 5-12 days, with a mean of just over 7.
Read the article knowing that:
1) The last datapoint I saw from it was Jan 20th - amazing that this hit print in just over a week from last data collection.
2) Look at how fast they closed the Seafood market - incredible how quickly i) they realized that this was a new virus, and ii) isolated it to the seafood market. I think that this shows just how far China has come on this matter since SARS.

It might be slowing. We will know more soon.
