To date, more than 557,000 people in the U.S. have knowingly tested positive for coronavirus or SARS-CoV-2. A new study, however, is looking to find out how many Americans have had COVID-19 that was not detected.
The study, being conducted by the U.S. National Institutes of Health (NIH), will attempt to figure out how many Americans have contracted the virus by looking for antibodies in their bloodstream, which would indicate a prior infection.
“In this ‘serosurvey,’ researchers will collect and analyze blood samples from as many as 10,000 volunteers to provide critical data for epidemiological models,” the NIH wrote in the release. “The results will help illuminate the extent to which the novel coronavirus has spread undetected in the United States and provide insights into which communities and populations are most affected.”
