Where does that article say anything about false positives? PCR tests are extremely accurate and almost never give a false positive to my knowledge so I'd be interested to know where you get the information that up to 5% of results can be false positives. |
I've seen an overview page yesterday about specificity and sensitivity for different PCR tests on the market but I can't find that site right now. The claimed range was 0.2-5% for specificity error (false positives) and typically less for sensitivity error (false negatives). I remember that common corona viruses increase false positives for Covid as well. Anyway what's the point of increased testing if all you get is something so close to nothing?
Netherlands are a more interesting example with a "second wave" of cases created by some real infections and increased testing. We could see a lag of about 1 week between cases and death during the first wave but now we got 4 weeks of second wave with no more deaths. Herd immunity achieved.
