People don’t need repeated tests for coronavirus once they have tested positive one time, Assistant Health Secretary Admiral Brett Giroir, a member of the White House coronavirus task force, said Thursday.
“This is a remnant of very early on when we had cruise ships and people were in quarantine,” Giroir said Thursday at a briefing at the US Health and Human Services Department.
With cruise ship passengers, a negative test was required to get out of isolation. The current guidelines say people can leave isolation if they have been free of symptoms for three days and it has been at least 10 days since the onset of symptoms. Guidelines also say people may leave isolation if they receive two negative tests in 24 hours. But Giroir said that two-test standard is no longer needed for most patients.
“We know that if you're 10 days since the onset of your symptoms, and at least three days … asymptomatic, you are no longer contagious. You do not need to be retested,” Giroir said.
Some people can test positive after they are no longer infectious because remnants of the virus remain in their bodies.
“What we're seeing is people getting tested three times, four times six times, probably, you know with good intentions, but they really do not need to be, so we want to get the word out,” Giroir said.
The exception, he said, is if a person is very ill and in the hospital. The virus can linger longer in those patients, as well as in people with immunosuppression or some immune deficiency.
He said that guidance from the US Centers for Disease Control and Prevention will be coming out about this issue “very soon.”
“The great majority of people who are diagnosed who are just sick at home do not need to be retested it's clogging up the system,” Giroir said. “And quite honestly, it does a disservice to them, because they can be quote positive for a much longer time than they are infected and it keeps them out of work, school, all those other things.”
