We had an expert one on TV answering questions, and one of the questions was the one I was burning to ask: "how do you know there are X infections per day"?

To what he answers "because we get data from pharmacies, doctors, etc. about cases"

- so how do you know that this is a total number? It is just the number of positive tests?

- yes, so we know the ratio and therefore can tell for the whole population

- so the number you provide is an estimate?

- no, the number of cases

(some time passed and then another question)

- when you extrapolate (they used a more human-friendly term), how do you know that the ones who come for tests are representative of the whole population

- ...

While I must say that our government reacted to the pandemic almost very well (except that they lied at the beginning), some of the experts they put ahead were ridiculous.
