false positives, not reinfections
Tests in recovered patients found false positives, not reinfections, experts say
The findings of this study suggest that most transmission of COVID-19 occurred at the very early stage of the disease or even before the onset of symptoms. […] High transmissibility of COVID-19 before and immediately after symptom onset suggests that finding and isolating symptomatic patients alone may not suffice to interrupt transmission, and that more generalized measures might be required, such as social distancing.

My problem with contact tracing apps is that they have absolutely no value. I’m not even talking about the privacy concerns, I mean the efficacy. Does anybody think this will do something useful? … This is just something governments want to do for the hell of it. To me, it’s just techies doing techie things because they don’t know what else to do. It has nothing to do with privacy concerns. The idea that contact tracing can be done with an app, and not human health professionals, is just plain dumb.
