Well you decide if China levelled with the WHO and the rest of the world.
On 31December, China notified WHO about a strange pneumonia - cause unknown.
Further reports until 3 January - causal agent not identified
Then China isolated a Coronavirus on 7 January.
Except for this...
China was isolating coronavirus from patients at least as far back as 26 December.
Given our experience with SARS and MERS, I think the world would have been interested in knowing about another deadly coronavirus.
That 2 week delay was very significant given what happened next.
