The biggest problem looking at these tests is that they are completely on the opposite side compared to the mortality estimated using South Korea numbers. We know for a fact that South Koreans tracked pretty much every single person with covid given that their new cases are increasing by a single digit per day. We know that as of today they have 10708 cases and 240 deaths, with still 1967 active cases. This give us a lower bound for the mortality at 2.2%. I think this is the best way to estimate mortality and I think that a lot of studies are giving numbers for the infected that are just out of touch with reality. I remember an Oxford study that was saying that half the UK was infected at the beginning of April. Those numbers were simply insane. I still don’t have a perfect explanation why the mortality numbers from the antibody tests seem so low, but I think that the accuracy of these tests or the way they select the people to be tested may be involved. Do you see any flaw in using South Korea numbers to calculate the mortality?
