Same as getting tested for flu that literally has zero effect on life with healthy people. Compare to August 2019 influenza testing which gave a 0.81% positive result rate, last weeks tests of what's being called Covid19, according to public health england was 0.55%, that includes Pillar one and two tests..
In England and Wales there are 5 times more people dying across the country FROM other respiratory diseases than those that have C.19 mentioned in the death certificate (that means they have not died FROM C.19 and pneumonia deaths are stil being attributed in the deaths column to C.19 as it has being throughout) the risk is tiny and less than any years flu at any time of the year and in every single previous year.
There is no need to self isolate, you might as well just cancel all human contact going forward at this rate, it's utterly insane and is killing more people through the actions taken than any virus itself could kill ultimately.
Aside from the threat being lower than flu, it's going to destroy the sport and others where no grass root sport is being allowed, this in turn has a huge effect on obesity which is the primary cause of so many serious ailments and deaths.
