Glad they’re just now admitting this after nearly two years:

PCR tests can stay positive for up to 12 weeks. Most of us have known the tests were not infallible, but until now, to say so was to be engaging in “conspiracy theorism.”
Walensky also addressed Tuesday’s news from the FDA that, according to early data, rapid antigen tests may be less sensitive when it comes to the omicron variant.
“We do know that the most sensitive test you can do is a PCR test,” Walensky said. “So if you have symptoms and you have a negative antigen test, we do ask you to go and get a PCR to make sure those symptoms are not attributable to COVID.”
The facade continues to crumble. The government continues its process of throwing in the towel on Covid.
