#Asymptomatics

Why do we need frequent testing over very sensitive testing? It’s easyThe average person is PCR+ for ~30+ days but infectious for ~7. Most people are asymptomatic. So, infrequent PCR

At this point it's very clear that we need a lot more rapid surveillance screening of asymptomatics who could be contagious with SARS-COV-2. We are piloting such screening in lab

Remember when I said that SARS-CoV-2 is far more widespread than realized?46.8% AB+ in Japan“C-19 infection may have spread widely across the general population of Tokyo despite the very low

1/x You'll be hearing a lot about the term "case fatality rate" in COVID-19 discussions. It's the reference indicator often used to compare how lethally bad COVID-19 is relative to

The economic stimulus bill co-authored by Cong. Stella Quimbo includes P20 billion solely for mass testing. If it gets passed, 20 million Filipinos could get tested, regardless if they are

@BBCr4today invited me to speak about lateral flow tests this morning (can listen at 0650). All government plans are now about using tests to "release" people - this depends on

As the NYT reported in an article you’ve probably read:“up to 90 percent of people testing positive carried barely any virus”Most correctly interpet this as evidence of the “Casedemic” being

People infected with #SARSCoV2 without noticeable symptoms (“asymptomatic”) can exhibit lung abnormalities upon chest CT. New paper in @NatureMedicine. However, despite no obvious symptoms, they make a robust neutralising antibody

PCR testing & the CDC controversy. Some thoughts. Per fascinating paper (see below), we are likely (1) infectious no more than 9d; (2) but can carry VL/test PCR + up

THREAD **IMPORTANT** (IMO)SO MUCH Continued CONFUSION about Rapid Antigen Tests - Now about Asymptomatics.A New @CDC_gov @CDCMMWR study concludes Ag tests didn't work in Asymptomatic ppl. Simply put, It's wrongHere

Example 2. Is PCR testing of asymptomatics a good idea? This man is COVID positive but has no symptoms at all. He says he has been completely healthy for the

Dear @HPA_MV since you are busy contact tracing,isolating the Positives,I thought the only way to MAKE YOU LISTEN IS BY ENVOLVING THE PUBLIC in this thread:1, Contact tracing will exhaust
