The age of the virus population ~ corresponds to the time the outbreak was detected (mid-December). This means China detected the outbreak - caused by a novel virus - almost immediately. In the middle of flu season. Deeply impressive

Of course these things have huge capacity for surprises. However, the good thing is that the rapid identification of outbreak and then the isolation of virus in the matter of days means countries are more prepared than in the past.
Yup, I agree Christian - especially the recent report of healthcare worker infections is deeply concerning. While the sequencing data does not prove H2H transmission, the data is consistent with that scenario (as well as others). HCW infections > highly likely H2H.
