Contact tracing, this late in the game, is beyond useless. Heck, by the time we realized it was here it was already too late.
Contact tracing, much beyond patient zero, is a fools errand.
So if you have family and friends who are very vulnerable to COVID-19 and someone you spent time with tested positive, you wouldn’t want to know about that? You’re okay with not knowing, contracting it, and spreading it to people you’re close to who could die from it?
I would really prefer a phone call letting me know that someone I was recently spending time with tested positive. If not from that person, then from an anonymous contact tracer is fine also. But that way I know to stay away from people who might die if they get this thing.
