Inconsistencies from the Centers for Disease Control and Prevention (CDC) and director Rochelle Walensky have continued as the Omicron wave sweeps across the U.S.
Walensky told the public in a Good Morning America interview Wednesday that PCR tests for COVID-19 can stay positive for up to 12 weeks after infection. For that reason, Walensky said, a negative PCR test would not be needed to leave quarantine or isolation under new CDC guidelines.
“So we would have people in isolation for a very long time if we were relying on PCRs,” Walensky told GMA.
Rapid antigen tests aren’t good indicators of whether someone is actually contagious with COVID-19, Walensky said. “We know it performs really well during that period where you’re initially infected, but the FDA has not at all looked at whether … your positive antigen really does correlate with whether you’re transmissible or not.”
Nearly two years into the pandemic, this is the first time Walensky has told Americans that they could be testing positive on PCR tests due to a COVID-19 infection that dissipated weeks ago, or that someone could test negative on a rapid test and still be contagious.
The episode is another instance of the CDC failing to keep Americans in the loop with the most up-to-date information on the pandemic.
The admission raises questions about the accuracy of the tests which the CDC has been basing its guidance on. (RELATED: Dr. Fauci Explains Why CDC Cut Isolation Period Down After Biden Warned About Winter Of ‘Death’)
Some doctors have warned for months that PCR tests can be oversensitive. But as commentator Yossi Gestetner pointed out, Americans have been forced to stay home, miss events and isolate themselves for almost two years now based on potentially false positives from oversensitive PCRs.
