I bet the false negative rate is quite high for self administered swabs

I don’t think so. My son is at college and had to self administer a test. He didn’t get enough sample from his nose, and the test did not come back negative..it came back inconclusive. So that tells me that a false negative would not be as common as you may think.

Thank you! This ridiculous "90% false positive" is becoming Twitter orthodoxy!

"closer to 0%" is a massive understatement - that could imply 44%. As the article itself makes clear, it's not just closER to zero, it's actually close to zero.

"The number of people who are sick with COVID-19 is increasing in many places in the world — particularly the UK" Really? It's less than 200 a day on a population of 66 Mil. Which works out at 6 hospitals per patient.

I fully agree in terms that PCR positive means detection of viral RNA, regardless of whether it is infective or not. But in terms of infectiveness, there are PCR + (>10-15 days after symptoms onset) which are very probably non-infectious.
