My wife has had it twice apparently and both times little or nothing to report. She is a nurse and works in multiple areas of her hospital including their Covid wing. She is now second shot vaccinated so probably won't get a positive result anytime soon.
The covid test is clearly easily susceptible to false positives and not to mention that given this Virus has never been isolated they must be calling many infections as Covid when they are just regular seasonal variants of Influenza.
After all if you take the test and get told you have Covid how do you really know what you're positive too, you don't. Influenza can kill you and if covid is something other than the current strain of influenza then it also can kill.
P.s The hospitals where she is are also claimed to be full in the media but the reality on the ground is not so where she works.
