"Setting: Diamond Princess cruise ship, Yokohama, Japan (n=-634 tested positive).
Proportion: 18%"
Also:
"23 Residents of a Long-Term Care Nursing Facility King County, Washington
10 (43%) had symptoms, and 13 (57%) were asymptomatic."
But then:
"Seven days after testing, 10 of 13 asymptomatics developed symptoms"
That means that just 3 of 23 remained asymptomatic there too, i.e. 13%.
It is estimated that the people mostly spread this virus exactly in the phase where they still haven't developed symptoms, and the virus can be detected. But that doesn't mean they will remain without the symptoms.
- asdf21 7y agoI suspect most people notice a bit of a cold or "allergies" Like you said, probably only 10% to 15% truly asymptomatic.
- arcticbull 7y agoThanks, I actually didn't realize the number drifted so much over time. Good to know! I'm curious how many of them were actually seriously afflicted vs. a stuffy nose. I'd argue almost 20% actually asymptomatic is still huge in context. Especially as we know the disease affects these demographics up to 100X more than the young. For instance consider: "Emerging evidence suggests many more people are infected than tested. In Vo Italy, at the time the first symptomatic case was diagnosed, about 3%, had already been infected – most were completely asymptomatic."

- DanBC 7y ago> a stuffy nose. Not a covid-19 symptom. EDIT: I'm wrong, sorry. Thank you to kgwgk for the correction.
