Not really, we've built a culture around pushing ourselves to work even when we are sick.
What would be more constructive than being scared is to work positively to end this culture.
Edit: to be really explicit, staying at home for several days when you feel sick and even after you think you have recovered should continue, even after the fear of the Coronavirus dies down.
Agreed that that should be a cultural change, and it'd be good for individuals, individual businesses, the economy, and society at large.
The fact that that viewpoint is representative of a broader cultural trend is genuinely terrifying, though. Even ignoring people who have to go to work in order to pay for food and housing (no legal requirement to offer paid sick leave!), there will be a very large group of people who believe it's virtuous to toughen up and go to work anyway, even if they feel like death incarnate.
