> dismissing the likelihood of somebody having coronavirus just because they haven't been to Italy. So yes, stupid.
The amount of infected people calling in who havent traveled is _infinitecimal_. The doctor saying you're not infected is correct an OVERWHELMING amount of the time, probably >99% accuracy. Eventually, this wont be true, but then the doctor wont be telling everyone to go away because theyre not stupid.
Now, if you want to argue the merits of extreme overcaution and attempting things like 100% testing for a global pandemic mitigation plan, good for you. You have a lot of hurdles to overcome, some of which you named yourself, but none of them are the doctors fault. You are simply wrong.
