I believe that’s it.
BTW, I don’t for a minute think the “official numbers” are completely accurate.
But even if the “real numbers” are 2x or 3x, it’s still just not wildly infectious.
In the 1918 flu epidemic, the second wave apparently started in September. By the end of October, over 20M Americans had contracted it, and by the end of October 650,000 Americans were dead.
Total number worldwide was around 40 or so million from what I have read.
