trillion dollar maths puzzle - we can only see data from tested world which as march 21 incidents of tests in thousands of humans - active 292, dead13, recovered 91 seems to be - typical questions discussed at economisthealth.com - if there are 10 times more untested cases does this mean death rate reduces from just over 4% to 0.4% - what further questions arise from march 21 with about 60% unrecovered - 13 days earlier data was showing about 60% recovered- so we have the issue that as the world does more testing its quite hard to understand how much recovery time varies for those that get severely ill but i cant find a way to predict from this data that a global olympics will be safe to hold unless everywhere ups its testing to korean or chinese levels of efficiency which wont happen in least developed countries without infrastructure or developed countries where testers make huge profits because testing inst normall a gov service
