Policies, procedures and semantics don't impact Covid numbers (Politically dogmatic CoronaBro Nation)
CDC guidance for testing full vaccinated people for Covid, policy changes as of late April:
For cases with a known RT-PCR cycle threshold (Ct) value, submit only specimens with Ct value ?28 to CDC for sequencing. (Sequencing is not feasible with higher Ct values.)
Translation, if you detect the virus above 28 then it's likely not symptomatic nor infectious (During 2020 labs were running cycles until they found the virus, or at least not stopping until they go to 35 to 40 cycles)
Also, let's try and hide the breakthroughs
As of May 1, 2021, CDC transitioned from monitoring all reported vaccine breakthrough cases to focus on identifying and investigating only hospitalized or fatal cases due to any cause. This shift will help maximize the quality of the data collected on cases of greatest clinical and public health importance. Previous case counts, which were last updated on April 26, 2021, are available for reference only and will not be updated moving forward.
If you're fully vaccinated and you're infected, we don't care, unless you go to the hospital. But we're still going to care a whole bunch if you're not fully vaccinated but display no signs of symptoms and don't have enough of a viral load to be infectious . . . we'll need that to continue to inflate the numbers as necessary.
