I just don't understand what they're afraid of.
That's the way most of the world felt on in September 2001. In response to an attack killing thousands, the West started wars which have since killed a couple of million people - and are still going 19 years later. 3,000 dead led to wars in Afghanistan, Iraq, Yemen, Somalia, Mali, Syria, and so on and so forth. So you might expect 225,000 dead from a virus has some response - well, from some parts it has an hysterical overreaction, and from other parts it has no reaction at all.
The nature of Western government is that it has only two possible states: apathy and panic.
Drugs, satanic child abuse, drugs again, terrorism, pandemic, whatever - every decade or so there's a moral panic about something or other, and the government brings in a bunch of new laws and imprisons or kills a bunch of people, mostly for no real reason.
