Joining the hosts of This Week in Virology in July, Fauci directly responded to a question about COVID-19 testing, specifically how patients with positive tests might determine whether or not they are actually infectious and need to quarantine.
“What is now sort of evolving into a bit of a standard,” Fauci said, is that “if you get a cycle threshold of 35 or more … the chances of it being replication-confident are minuscule.”
“It’s very frustrating for the patients as well as for the physicians,” he continued, when “somebody comes in, and they repeat their PCR, and it’s like [a] 37 cycle threshold, but you almost never can culture virus from a 37 threshold cycle.”
So, I think if somebody does come in with 37, 38, even 36, you got to say, you know, it’s just dead nucleotides, period.”
Like I've said multiple times, PCR lets you find the needle in a haystack and unless extremely-well documented, a PCR positive on Cycle "X" for any disease has no defined infectivity associated with it. The infectious dose for COVID-19 will likely vary by variant and differ between unvaccinated, semi-vaccinated (1 dose of Pfizer or Moderna), and fully vaccinated people.
All that being said, as Fauci said, 35 Cycles or greater COVID-19 positive results, probably have little value in determining if a person is infected/and or infectious to others or not. Many assays, but not yet COVID-19, have "Gray Areas" where a retest is required 2 to 3 days after the initial Gray Area result. Actually surprised that this hasn't been specified for COVID-19 yet, but guessing that during the early days, the testing demand far outstripped test availability.
