Not the disease, just the panic. By discussing this thing to the extent that it has been discussed, businesses will be ruined, people who depend on those businesses to pay their medical bills, prescriptions, food, etc are in for a had time. Some wont make it.
No, the impact is caused not by panic but by rational and very much needed measures to limit the spread of a deadly disease for which there is no cure. True, it doesn't kill many people under age 40, but if all those people regard these measures as "panic," and refuse to comply, then they will be passing the disease to their friends, neighbors and relatives over age 60 and those under age 60 with health issues.
Every natural disaster has businesses that are impacted, and sometimes ruined. When I lived in the snow belt, if there was a winter or two with no snow, ski areas were in danger of going bankrupt, and if there was way too much snow, restaurants and other businesses that rely on pedestrian traffic lost money big time. This is life. Life is uncertain. And that's what we are seeing here, too.
