I don't understand what you think is to be saved by inciting panic. There's plenty of coverage, all this classification does is open up money from the IMF I believe. A Pandemic classification doesn't change most people's behaviors, but it does cause toilet paper/hand sanitizer shortages.
At least in the US, companies and other organizations are hesitant to be the first ones to stick their necks out and cancel events/encourage remote work. Our federal government's incompetent/evasive/opaque response to the crisis has let the burden fall on local governments in the hardest-hit areas.
Labeling this a pandemic would have given cover to organizations that wanted to be more cautious but were afraid of "looking stupid".
