Here is the most important fact about Covid-19: Trump has done everything possible to sabotage and limit the number of tests. Remember:"anyone who wants a test can get a test". Or when he didn't want an infected cruise ship to dock because "I don't like those numbers". Simple arithmetic can give a reasonably accurate picture of the total number of cases. There has been about a 13% positive test rate so far. If you apply that number to the total population you get about 40 million current cases. Again, no complex math-just 3rd grade arithmetic. Hell of a scam, I guess. Don't fall for the inane blatherings of a moron, in this case Trump. Very sad.
