I wonder if there isn’t a certain element of hindsight bias here. Now it’s clear that more action should’ve been taken earlier. But knowing the panic this has caused, not to mention the economic, global logistics and travel impacts I don’t know if it was such an obvious situation at the time. Especially when the vitality, severity and mechanism of transmission etc weren’t clear. CCP policy and behavioral patterns aside, I can see the local official in charge wanting to avoid being the guy that caused a bunch of public panic over nothing.
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.
