By the end of its odyssey, a total of 712 of them tested positive, about a fifth.
Perhaps other on the ship had already cleared the virus and were asymptomatic. PCR only works for a week. Also there might have been false negatives. I disagree that the age and comorbidity structure can only lead to skewed results by a factor of two or three, because this assumes that there are few asymptomatic infections (I’m arguing here that the age tables are wrong).
In my post, I’ve argued why the data out of China might be wrong.
Iceland’s data might be wrong because it is based on PCR not serology, which means that many people might have already cleared the infection, and it is also not random.

That’s the Grand Princess, not the Diamond Princess.
Cheers- corrected.
