New study suggests COVID-19 prevalence in U.S. far exceeded

A new study of the U.S. National Institutes of Health (NIH) showed the prevalence of COVID-19 in the United States during spring and summer of 2020 far exceeded the known number of cases, and that infection affected the country unevenly.
NIH researchers estimated that there were 4.8 undiagnosed cases for every diagnosed COVID-19 case in this time frame, representing an additional 16.8 million cases by July alone, according to the study published on Tuesday.
The team recruited over 240,000 volunteers from across the country, then selected 8,058 individuals from that pool through quota sampling to ensure that their study cohort was representative of the U.S. population.
