In authoritative countries the messenger of bad news tends to be 'disciplined', and so bad news is not delivered. It still exists, but no one wants to be the individual that creates the (negative) feedback loop that may be contrary to the diktat that came down from on high.
Of course hiding bad news happens in less authoritative countries as well (being the "tall poppy", Law of Jante, 「出る杭は打たれる」), but the consequences may be less severe.
There was all sorts of secrecy with SARS many years ago, and it seems that China has still not completely broken that 'habit':

Imagine if things went the other way. Big announcements of a new virus, people panic and hoard food and supplies. Travel gets restricted and Wuhan gets quarantined. And not much happens. A few people get sick and quickly recover. I’m not sure if the guy will get praises for acting swiftly.
I read on twitter around Dec 31 that there was such a virus spreading in Wuhan. Around Jan 1, the Wuhan police dep publicly condemned 8 person (the origin of the twitter news) for spreading this information and called it a rumour. Then the gov did everything to hide info and did nothing to prevent its spreading before around Jan 2x. They behaved even like they want to spread it as much as possible because just about two to five days before they made the announcement of the virus outbreak, the Wuhan gov organized a so called 40k family new year banquet -- around 40k Wuhan local families were concentrated together to have a banquet to celebrate the coming Chinese new year. All the events I cited here can be found on China's own newspaper and tv recordings.
I have a hard time imagninig something like this happening in many Western countries. It might happen, but in my view it's far more unlikely.
I’m not dismissing the initial attempt at cover up here and the Chinese government should seriously examine their priorities. I just think it’s a bit of an exaggeration to link this event to causing a “big disaster for whole human society”.
