Covid-19 - Second time testing positive

So at the beginning of March my wife came down with a nasty cough and predictably tested positive for Covid. We both felt slightly unwell but nothing more than just feeling a little bit crappy, a bit like waking up after a night on the beer. I had a slight relapse with my arm (a previous issue area) but I never had really bad issues with my breathing like others have had. Last week as part of my wife's employers testing policy she once again tested positive. We both live together so have both been concerned what the effect of me catching the virus again might be. I am cautiously positive to say that once again we BOTH appear to be fairly unaffected by the virus and it would appear that both of our bodies have built up some sort of protection. I am on Tecfidera and had been concerned that this may cause an issue with my immune response. So far so good though and fingers crossed this virus is starting to have a less of an effect on people second time around.
