I am struggling to understand, are you saying there were no positive Sars-Cov2 patients since the middle of July at the hospital you are at?

And have you seen any cases of catching Covid 19 the second time (reinfecting with the same virus). I did read about such cases abroad I think.

Also, as a data person, testing even the healthiest of the nation helps to see clusters and spot trends which were not considered before. We do need data 😉 even if it is a sample.
