The CDC has estimates for the data you asked for here: https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/burden.html https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/burd... In the USA, by March 2021, there were 114.6 million estimated total infections, 5.6 million estimated hospitalizations, and 17.5 million estimated asymptomatic infections. That predicts approximately 1 in 3 Americans were infected with the virus. These numbers make sense to me, and I can show this with back of the napkin math. A few global studies estimated the average infection fatality rate to be between 0.4-0.7%. Using a 0.6% death rate and the reported 600k deaths in the USA, that gives 600,000 / 0.6% = ~100 million infected in the USA. So the CDC numbers look alright.
