Iceland mass testing-> estimates 1% COVID+ and 0.25% CFR. Cruise ship data yields similar results. Are these results applicable to wider world?

Cruise #'s include crew and still skews old. Ten people died- none below 60-69 bracket, many in 80's. We don't know exactly WHY they died. IFR= infection fatality rate. We don't know infected#- eg, how many had SARS-Cov-2 which causes COVID-19- only who tested+ at certain time.

We don't know who had it but beat it to the pt it didn't show up *at time tested*. They'd be an "infected" but not a "case." They tested old first to young. We know that 10 ppl w avg age in 70s died, .26% of total on cruise that skewed old w optimal condition for spread.

Good point, but how long do you test positive for after you recover? They weren't on the cruise ship that long and they did the testing pretty fast when there were a good number of people with symptoms.
