Why is this important?

PCR positive for #COVID19 does not mean you are infectious
It means you have virus RNA
Like DNA left at a crime scene, it doesn’t mean the virus is still there
Virologists cautioned about equating PCR to live virus since the start of the “molecular revolution” in clinical labshttps://twitter.com/covidpath/status/1296959950808158209 …

To clarify the top tweet, it COULD mean you are infectious, but might not. A PCR with a very low Ct value means you are very likely infectious, should be isolated and contacts traced. Interpreting the Ct value is extremely helpful at the low Ct (high viral load) values to triage

This is a terrific report on this issue from S Korea.https://www.cdc.go.kr/board/board.es?mid=a30402000000&bid=0030&act=view&list_no=367267&nPage=1 …

That’s why need
#sonananotech 100% accurate for asymptomatic people .best rapid test out there -
Hi. I worry that saying it is 100% isn’t helpful. No lab test is 100%. And certainly not an antigen test. A lot of investors invested in Sona. Not a bad thing, but the 100% accurate claim just doesn’t help Sona. I think it may raise the level of skepticism.

Do all infectious folks have positive PCR? Can PCR be useful in finding asymptomatic/presymptomatic folks?
-
Absolutely it can. Has to be done with care though. A repeat test of a positive at 24 hours later can be extremely informative to know if you are picking up low viral load in pre/asymptomatics before transmissible, or, more likely, too late, after transmission has ended.

Really important point, that's why your push for quick and dirty and constant lateral flow testing is the bomb

Not related to the graph, but "publication"... Back in May South Korea reported that issue about PCR test results and infectivity.https://www.cdc.go.kr/board/board.es?mid=a30402000000&bid=0030&act=view&list_no=367267&nPage=1 …
