“In order to understand the proportion of the population that’s been infected with COVID-19, and what proportion remains at risk, CDC is currently performing large-scale serology testing across the United States,” Dr. Robert Redfield, CDC director, said on Wednesday during a Senate Health, Education, Labor, and Pensions Committee hearing.
According to previous literature from the CDC, many commercial laboratories refer to serology tests as an antibody test.
Most Americans likely remain vulnerable to coronavirus infection and its associated outcomes, per comments from Dr. Robert Redfield, director of the CDC. Redfield is pictured here on Capitol Hill in Washington, Wednesday, Sept. 16, 2020. (Anna Moneymaker/New York Times, Pool via AP)
“Preliminary results appear to show that most Americans have not been infected with the virus and are still vulnerable to the infection, serious illness and death," Redfield said.
Redfield said the health agency hopes to post the analysis from the first round of the study in the next several weeks.
According to data from Johns Hopkins University, the U.S. is approaching 7 million reported cases of COVID-19. In late July, Redfield issued a statement saying the CDC's "retrospective estimate is that there were 10 times more cases than reported from the period where we’ve been examining antibody data: March through May." The U.S. has a current population of around 330 million people.
