stefan but you missed my point, it is running uncontrolled through the population here. Knowing that you are negative one day does not guarantee you are still negative the next day or week by making one mistake in someone coughing near you for instance. Then its back to the test centre again over and over - this is ridiculous!
We do this only when we have developed symptoms. We catch 2% covid cases by this and they can start tracking and warn others. My exwife was warned by tracking procedures and stayed cool, possibly sparing me an infection.
