I disagree. Ride that horse all the way to Dodge City and back again, because people have the attention span of gnats and "get bored" with sheltering in place, thinking of others, etc, and all of those difficult, grown-up things.

This pandemic is not "unknown." The science of epidemiology is well-established. The virus is spread mainly via air and sometimes surfaces. This means that all of the advice you quoted is valid and will have gone a long way to mitigate the spread. And I don't know what the advice has been where you are, but contact with others was supposed to be minimized. No visitors to your home. No visits. People should not have been leaving their homes except for absolute necessities, which are food and medications.

The problem seems to be in updating the advice as more becomes known, which means even stricter guidelines, and communicating that to a public who can't even cope with the current advice because, you know. "Freedom."
