Diamond Princess data. This dataset is particularly useful because everyone on board the ship was tested, meaning asymptomatic infections could be caught. (h/t @habryka for link)
Shows the # of asymptomatic cases by age group. I couldn’t determine how long after exposure these people were tested, so this should be treated as an upper bound for percent-asymptomatic, not the average. One interesting thing is that people in their 20s and 30s had a much higher rate of symptoms (80%+) than older or younger people (< 60%).

That’s indeed interesting. This article seems to say that it’s different in young people who tested positive in South Korea.
One point of criticism about the link included under “Diamond Princess data:”
The abstract reads as follows:
Comparing deaths onboard with expected deaths based on naive CFR estimates using China data, we estimate IFR and CFR in China to be 0.5% (95% CI: 0.2–1.2%) and 1.1% (95% CI: 0.3–2.4%) respectively.
This wording to me suggests that the authors think 0.5% is most likely the correct IFR for China’s cases (up to a certain point in time, based on when the paper was written). This is either false, or the authors are making a really obvious mistake. The paper did not factor in that sick people in Wuhan (where most of China’s cases were from at the time) probably had much worse treatment prospects than patients from the cruise ship.

This shows that deaths peak 4 days after hospitalization and then have a long tail. Time to hospitalization is not specified.
