Original Note:
This is a misrepresentation of the document. The CDC set a benchmark to determine which positive breakthrough samples are further analyzed for evidence of a variant. The PCR cycle threshold has not changed. PCR tests do not have a 97% false positive rate https://www.politifact.com/factchecks/2021/jun/03/tweets/cdc-did-not-change-its-criteria-what-considered-br/ https://virologydownunder.com/the-false-positive-pcr-problem-is-not-a-problem/
