> And I think about how in the restaurant business how a rumor of someone catching food poisoning can kill your business... what's going to happen when a review lands on your Yelp/Google page that a customer took grandma to eat at your restaurant and 2 weeks later she died from COVID-19? Your reputation will be absolutely trashed.

tbh, I don't think this would be as devastating as you say. "went to restaurant, died two weeks later" is not as clear a connection as "ordered shellfish, puked guts out next day". the thing that's so bad about food poisoning is that, not only does it suck, but it strongly implies a dirty kitchen. in my experience, people are disturbed more by the abstract thought of an "unclean" kitchen than concrete fears of getting sick.
