Thanks for the links. It seems that the response went along the following timeline according to my understanding:
1. Dec. 30 - Doctors from the first few cases have analyzed the samples and discover how similar the new virus is to SARS. Officials tell them not to spread information to the public about the virus.
2. Dec. 31 - China tells WHO about new virus (not that they know much at this point)
3. Jan. 1 - Provincial health committee orders provincial labs to destroy samples, samples are transported to larger state facility to do testing there. The reason for this is due to the samples being considered "highly pathogenic microorganisms", and that only approved facilities should test it. (I'm guessing due to the risk of acting on the sample and contracting it?)
4. Jan. 2nd - State approved facilities map the genetic sequence but an official national statement doesn't get made until a week later, Jan. 9th.
So from lab work, until international statement, that's two weeks. During that time, wouldn't it make sense for the doctors and researchers to keep their results hidden until it can be verified lest they risk causing unwarranted panic? Considering how carriers of COVID19 can be asymptomatic [1], it does take time for verification to be done on whatever discovery a nation makes on the world stage. In hindsight, it's easy to say that they should have jumped the gun and done exactly that on whatever communications platform were available to them. However, had COVID-19 turn out to be a minor disease, that'd mark the end of all their careers.
> Jan. 11–17: Important prescheduled CCP meeting held in Wuhan. During that time, the Wuhan Health Commission insists there are no new cases.
> Jan. 14: WHO announces Chinese authorities have seen "no clear evidence of human-to-human transmission of the novel coronavirus."
> Jan. 20: The first case announced in South Korea.
Zhong Nanshan, a top Chinese doctor who is helping to coordinate the coronavirus response, announces the virus can be passed between people.
> Jan. 23: Wuhan and three other cities are put on lockdown. Right around this time, approximately 5 million people leave the city without being screened for the illness.
> Jan. 24–30: China celebrates the Lunar New Year holiday. Hundreds of millions of people are in transit around the country as they visit relatives.
Where in this timeline do you see evidence that information their healthcare system had suggesting how severe COVID-19 was, was being intentionally covered up? I just see how unfortunate it is that they realized COVID-19's severity too late, else the Wuhan residents who left prior to the lockdown would not have been able to travel as freely as they did.
I think that shows exactly that China didn't realize how bad this was. For example, from the NPR link:
Jan 18: Wuhan hosts a holiday banquet for 40,000 attendees, despite reports of a contagious viral pneumonia.
We've seen similar things in so many countries - people don't understand how bad it is until lots of people start dying. China put 21 million people on lock-down when there were only 619 confirmed cases - compare that to elsewhere.
