The town that had the first recorded infection in Italy tested its entire population and found that only 3% were infected. About half of them were asymptomatic. This Oxford study is BS.
That doesn’t mean they haven’t already had it or it was such a mild case it didn’t register enough with assympomatic (same reason lots of people had to have multiple tests done). It’s why you do an anti-body study. It’s how they figured out the swine flu was only .02% death rate rather than the 1-5% originally thought.
You’re comparing apples and pineapples.
