What I fond interesting from some of the graphs were the death rates. UK's percentage is 5% which looks very high IMO at this stage. Whereas some other countries it is quite a low percentage. I wonder if part of it will be due to the amount of testing being done, so there could be a lot of people who have it, but they aren't being tested, and they also may be quite mild.
The death rates will mean very little until antibody tests are widely available and even then will be lower than they should be because of the lack of testing for severe cases or post mortum testing and how a country decides to classify deaths(ie if they are covid caused or if it contributed in addition to other medical issues). You then also have the deaths of people who need unrelated ICU care but didn't receive it because of the hospitals being overloaded.
The real way we will know is months down the track comparing average deaths(by season) of previous years vs 2019/20 and how many people test with antibodies(assuming they last a reasonable length of time).
