You forgot the one thing that makes everything relying on a fever completely fucking stupid: NUMEROUS illnesses and even some body issues that aren't an illness AT ALL can cause a fever/rise in body temperature. Getting a sunburn can give you a fever. Some women get a fever between ovulation and their period. I had a fever on and off with Lyme Disease, which was never CONTAGIOUS.

If people want to lose business by being this retarded, then fine. But the second somebody is accused of having Covid-19 when they've tested negative and they have some other health issue or a normal body doing normal body things, a shitshow should occur.
