“From the data we have, it still seems to be rare that an asymptomatic person actually transmits [#COVID19] onward to a secondary individual...It’s very rare.”

2/ This is a particular interest of mine. As discussed previously, "asymptomatic"
#COVID19 is a term that is often misused during the course of this pandemic.@ADetsky@kakape -Aysmptomatic -Pre-symptomatic -Pauci-symptomatic These distinctions matterhttps://tinyurl.com/ybwzhj3s2 replies 20 retweets 60 likesShow this thread -

3/ The problem is, few studies readily distinguish between these groups.https://twitter.com/BogochIsaac/status/1268899571012456449?s=20 …

Isaac BogochVerified account @BogochIsaac1/ A great study on asymptomatic#COVID19 infection & transmission: 14000 tested via PCR, 49 positive, 30 participated in study 13/30 (43%) NEVER had symptoms (truly asymptomatic) Asymptomatic have lower viral load & faster time to viral clearance https://bit.ly/2A68mSH pic.twitter.com/i6xvwEE4EWShow this thread5 replies 5 retweets 27 likesShow this thread -
Replying to @BogochIsaac
Give them the importance of this question, and many studies showing asymptomatic or presymptomatic transmission (which essentially has same practical consequence—people cannot rely on symptoms), I’m befuddled that they say this without releasing a report on the underlying data.

Plus of course the subclinical, as you say. And there have long been reports/papers about atypical clinical presentation, too. How can things be this confusingly communicated, so many months into a pandemic?
