Some people appear to be confused about the methodology involved in false positives and false negatives (which shockingly includes our Health Minister.) It is explained here: https://www.spectator.co.uk/article/how-many-covid-diagnoses-are-false-positives- and here: https://lockdownsceptics.org/lies-damned-lies-and-health-statistics-the-deadly-danger-of-false-positives/ if you read these studies and understand them, you will no longer need need to question their veracity here. Update: It is well explained by this New Zealand doctor for example: Why Are Covid-19 Cases Soaring In New Zealand? PCR Test Update: https://www.youtube.com/watch?v=kcONxyAJ8S4 Also good commentary here: COVID – why terminology really, really matters (Dr Malcolm Kendrick): https://drmalcolmkendrick.org/2020/09/04/covid-why-terminology-really-matters/
