As per Snowboarder_Bo’s daily posts in the Breaking News thread on the COVID-19 numbers, as of yesterday, there were 5,841,428 confirmed cases of COVID-19 in the U.S. 5.8 million is a lot of people, but that’s still only 1.8% of the U.S. population.
So, unless you live in an area that’s been hard-hit (e.g., New York City, portions of Florida, Arizona, and California, etc.), or you have a lot of interaction with elderly and other at-risk people, odds are pretty high that you still wouldn’t know many people who’ve definitively had the virus.
