> China has stated that they think it can be contagious before symptoms. The US has stated as of yesterday (Jan 27) that there is no evidence for that yet. IIRC, the US hasn't seen the evidence for that yet, but they're also complaining that China's not sharing data with them. The CDC is getting its info from China from press briefings like everyone else.
