In the early days, you were only tested if you had been abroad or in contact with an infected person.
The theory is now that there was no patient zero. Logically this makes sense. It's believed Covid came into the UK in at least 1300 instances.
If we had tested en masse at the start, case incidents would be much higher and our case climb much steeper.
So is it fair to say that when we have 10 cases a week in our local areas, we are less likely come across infected people than before lockdown with 10 cases when we didn't have the testing to know how rife it actually was.
