We know their infections were radically beyond the 80,000 they claim. For exmaple we know they changed their qualifications in late January / early February, to hide infection numbers by dropping non-severe results (which produced a fake taper off in their case expansion at that time). However, it would be an immense service to the world, if we could find out just how widespread the virus really is in populations. If anyone could do a million blood tests in a short amount of time, it would be China.
Did herd immunity help China bring the outbreak under control in Wuhan, because it had hyper spread there? It's crazy that we still don't know basic things like this.
Has Italy really had 500k-1m cases of it, not 47,000? Such that it took that many cases in the general population, most undocumented, to generate the ICU overload they're seeing.
It changes everything about how we handle the virus over the coming months, if it has already spread in large numbers across the population. Some large population country with a lot of infections needs to do this asap. China, US, France, Spain, Italy, Germany. Even Switzerland at this point might give us the data we need. Do they really have 60,000 cases, rather than 6,000?
