CDC Mulling COVID-19 Test Requirement for Asymptomatic: Fauci
WASHINGTON — As the COVID-19 omicron variant surges across the United States, top federal health officials are looking to add a negative test along with its five-day isolation restrictions for asymptomatic Americans who catch the coronavirus, the White House’s top medical adviser said Sunday.
Dr. Anthony Fauci said the Centers for Disease Control and Prevention is now considering including the negative test as part of its guidance after getting significant “pushback” on its updated recommendations last week.
The Dec. 27, guidance reduced isolation requirements for COVID-19-infected people from 10 to 5 days, if they no longer feel symptoms or run a fever. The patient is asked to keep a mask on their face for the next five days.
Many health professionals have criticized the guidelines for failing to specify a negative antibody test for isolation.
“There has been some concern about why we don’t ask people at that five-day period to get tested,” Fauci said. “Looking at it again, there may be an option in that, that testing could be a part of that, and I think we’re going to be hearing more about that in the next day or so from the CDC.”
Fauci, the nation’s top infectious diseases expert, said the U.S. has been seeing almost a “vertical increase” of new cases, now averaging 400,000 cases a day, with hospitalizations also up.
“We are definitely in the middle of a very severe surge and uptick in cases,” he said. “The acceleration of cases that we’ve seen is unprecedented, gone well beyond anything we’ve seen before.”
Fauci said he’s concerned that the omicron variant is overwhelming the health care system and causing a “major disruption” on other essential services.
“When I say major disruption, you’re certainly going to see stresses on the system and the system being people with any kind of jobs … particularly with critical jobs to keep society functioning normally,” Fauci said. “We already know that there are reports from fire departments, from police departments in different cities that 10, 20, 25 and sometimes 30% of the people are ill. And that’s something that we need to be concerned about because we want to make sure that we don’t have such an impact on society that there really is a disruption. I hope that doesn’t happen.”
While there is “accumulating evidence” that omicron might lead to less severe disease, he cautioned that the data remains early. Fauci said he worries in particular about the tens of millions of unvaccinated Americans because “a fair number of them will get severe disease.”
To protect himself and reduce the U.S. case surge, he urged Americans to get vaccinated.
According to the Food and Drug Administration, preliminary research suggests that at-home rapid tests can detect microns. However, it may be less sensitive. The agency noted it’s still studying how the tests perform with the variant, which was first detected in late November.
Fauci said Americans “should not get the impression that those tests are not valuable.”
“I think the confusion is that rapid antigen tests have never been as sensitive as the PCR test,” Fauci said. “They’re very good when they are given sequentially. So if you do them like maybe two or three times over a few day period, at the end of the day, they are as good as the PCR, but as a single test, they are not as sensitive.”
The PCR test must be performed in a laboratory. The test looks for the virus’s genetic material and then reproduces it millions of times until it’s detectable with a computer.
Fauci suggested that Americans might soon see some normalcy in their lives if they took the appropriate precautions.
“One of these things that we hope for is that this thing will peak after a period of a few weeks and turn around,” Fauci said. He expressed hope that by February and March, omicron could fall to a low enough level “that it doesn’t disrupt our society, our economy, our way of life.”
Fauci spoke on ABC’s “This Week” and CNN’s “State of the Union.”
