“First question? What is the rate of false positives and false negatives in these tests?”
It doesn’t matter as much when the prevalence is relatively high.
If the prevalence is low like 1% then a false positive rate of 1% could mean all the positive cases are false. If the prevalence is 10% it would have to be a really bad test to have all the positives be false.
BTW this study establishes, once again, an infection mortality rate of more than 1%. 46mm population in Spain, times 5% (the percentage of individuals with infection, based on 70,000 tests of random people in the population) is 2.3mm. There have been 27,000 deaths in Spain, so the infection mortality rate is about 1.17%. This number is remarkably close to the NYC infection mortality rate.
Sorry Flubros, it’s least 10 times worse than seasonal flu.

Sounds like 3 million people got infected in Spain. So it looks like for every confirmed case, 10 people did not get tested. If we do the same in USA, it would be that around 20 million Americans got infected so far.

"If the percentage of infected people who eventually die is around 1.1%, as the study suggests, the cost in human lives of herd immunity would be between 200,000 and 300,000, making the method unacceptable. Epidemiologists consulted by this newspaper said that social distancing measures must remain in place until a vaccine becomes available."

Thanks, No, I am not a flubros and believe this is a serious disease and APPROPRIATE pulic health measures are in order. I have questioned the false positives, because for some result I have seen it has to be in the 5-30% range, which can indicate that it is widespread when no one actually has had it. The flubro story is that it already spread everywhere, antibody tests show that and so we are close to herd immunity.

You just have to shake your head in disbelief at that sort of nonsense and ask where are all the dead bodies from this disease that we didn't even know was hear. And remember that's how the disease was initially identified in Wuhan - pneumonia and death.
