At the time of the study, Santa Clara county had 1,094 confirmed cases of Covid-19, resulting in 50 deaths. But based on the rate of people who have antibodies, it is likely that between 48,000 and 81,000 people had been infected in Santa Clara county by early April – a number approximately 50 to 80 times higher.
That also means coronavirus is potentially much less deadly to the overall population than initially thought. As of Tuesday, the US’s coronavirus death rate was 4.1% and Stanford researchers said their findings show a death rate of just 0.12% to 0.2%.
But that’s rather lower than the reported – and there will always be missed infections, of course – death rate of regular ‘flu. If true then we face the obvious question, we killed the economy for this?
