Yes on the second. But if it were more contagious than the flu then 100 million Chinese would have it right now. But they don't, so it's not.
Pence said it wax 2x or 3X as contagious so I’ll go with that as he has the best sources.
On the other hand how are China and S. Korea getting it under control. Perhaps S. Korea has a milder strain. Seems like its too soon for heard immunity to kick in.
Really don’t trust any news from China.
