I think it is very widespread (much more so than reported), but the numbers are badly distorted in a variety of ways. Take a look at the numbers over here for example: https://www.worldometers.info/coronavirus/#countries
Under ‘Columns’ turn on ‘1 Test every X people’. You’ll see that for the U.S. that number is 1, or 1 test for every 1 person. That makes it sound like everyone is getting tested here, which is complete bs. Most people aren’t being tested, even lots of people who are symptomatic. Apparently enough people are getting multiple tests to make up for everyone else who isn’t getting tested, which I also call bs on. And I would wage a healthy bet that if something nearer complete population testing were to happen in the U.S., there would be wayyy more asymptomatic cases. I do ask around alot to find out who has been tested, and everyone is surprised by that number. Any way, that one number alone, number of people being tested, already distorts things alot by giving the impression that all the other numbers have more legitimacy than for many other countries.
On cases and deaths, lots of us probably know something about how those numbers are being inflated, which I think has been talked about here already. That isn’t to say that there hasn’t been a significant number of Covid cases and deaths, but when it it made profitable for healthcare facilities to count more cases and deaths as being Covid, of course the numbers will be inflated. See for example:
And on Covid death counts:
