What are you talking about ? A random sample with positivity rate of 20percent would indicate one in 5 has covid. Why are you posting such conspiratorial comments with a throwaway account ?
Would you please stop posting in the flamewar style to HN? You've been doing it repeatedly and we ban such accounts.
Please don't attack fellow users and please omit swipes like "What are you talking about" from your comments here. If another comment is wrong, it suffices to reply with accurate information. Actually it's much more credible that way. If you toss in gratuitous swipes, you discredit the accurate information you're (by hypothesis) adding, which is bad for the truth.
