Testing for Covid-19 is useless says Knut Wittkowski


Whatever you think of his other opinions the Nut, as a friend of mine calls him, is pretty obviously right about the uselessness of testing for Covid-19. 

Where I suspect he is mistaken is when he says antibody testing can tell us how far we have progressed towards achieving herd immunity. The answer the tests give is that we are a very long way off it, but quite a lot of people suspect that many more people are immune than have antibodies, which may be why the virus seems to fade away after two or three months in each country infected.
