pretty concerning if you are over 60, and probably not worth even worrying about if you are under 45 except for the fact that you can infect vulnerable populations (please note, I'm not saying you can't die, I'm saying it doesn't seem to have reached a percentage where a rational person should be concerned regarding their OWN health).
The problem my family is running into is that the vulnerable population in our immediate vicinity don't seem to care. They'd just assume we keep visiting them as normal. My anti-social attitude is carrying the day still. I don't know how long that will last.
