Return to the question about did China lie. Well, I see the reaction from the Chinese government in 2 line, on the scientist's side, they had acted fast, made the DNA sequencing very fast this time, and alerted the WHO very earlier on the beginning of the January. As I mentioned, the serious cases hit hospital was in December, although it started in November, it dint' get people's attention.They published report of the first hundred cases very fast. You can get all these information from WHO easily.
The other line, to the local public. They tried to contain the news , as it was Chinese new year, I think local government wanted a good show, they allowed lots of big events on which was a big mistake. Then situation got worse quickly in hospital, the government now found out this virus was very hard to be contained and can cause serious damage, so they did a strict lock down on Wuhan. I think this was a quick and correct reaction, although lots of people are still questioning it.
For the figure from China, I think it is hard to say how many actually got it, as so many had it without symptoms, you can only know by testing everyone, which is impossible. But I think the current low case situation should be true , as in most places , people started to work and social again.
