No matter the actual figures, which I take with a pinch of salt anyway, the fact is that flu has a vaccine, has always been with us and always will be.
COVID 19 was and still is a relative unknown with no current or proven vaccine, so a belt and braces reaction was always on the cards. I don't like quarantine any more than anyone else, but I do feel that it's helped reduce the spread and in our household we are still taking active precautions.
This is not just another flu epidemic.
