Researchers Estimate Undiagnosed COVID Cases Doubled Confirmed Case Count

Researchers estimated 16 million people in the United States may have had undiagnosed, asymptomatic COVID-19 as of September 2020 and this was double the 7.5 million confirmed cases.

Testing has increased. However, the tests are trying to detect active cases of COVID. The ratio of undiagnosed cases to confirmed would gradually reduce. There are now 30 million confirmed cases in the USA. The upper bound of undiagnosed cases would likely be another 60 million. This would mean up to 27% of Americans have confirmed or could have had COVID.

The percentage who have had COVID is not 9% (30 million) but likely 20-27% (65 -90 million).
