33 million people have tested positive. Two-thirds of cases are asymptomatic, so tons of people got it and never tested positive. Turns out my 80-100 million number is way outdated. The number of people who have had covid /= those who tested positive.
April 2021: CDC estimates 115 million Americans have had covid:

February 6th, 2021: Columbia University: Over 100 million people have had covid:
Not everyone gets tested. A new model estimates how many infections are missed because of this and how many people are actively shedding the virus. The results lend urgency to the vaccine race.

February 4th, 2021: 71 million have had it:
World health experts have long suspected that the incidence of COVID-19 has been higher than reported. Now, a machine-learning algorithm developed at UT Southwestern estimates that the number of COVID-19 cases in the U.S. since the pandemic began is nearly three times that of confirmed cases.

A study last September estimated 60 million:
A lot of Americans have been infected with SARS-CoV-2. Extrapolating from a new study suggests that the number may be as high as 60 million. Unfortunately, herd immunity is still a long way off.

This all makes sense though. If the CDC is correct in that 115 million Americans have had covid, then you'd expect us to be entering herd immunity right now at our level of vaccinations, and it sure looks that way.
