>>Plenty of cases of COVID are mild enough to resemble a regular old cold.

Anecdata: I have a friend who had no idea she had anything when she tested positive. She was in Mali, had to take an antibody (not PCR) test that showed negative before she got on a plane. She tested as she was returning to the US. She'd had all the vaccines and boosters then-available in the US, never had more symptoms than a sniffle, but her friends there (who had *not* had access to the same vaccines and boosters) got quite sick.

The doctor there gave her antibiotics. She didn't take them as she knew those work on bacteria, do nothing for a viral issue - and she didn't have a cough so pneumonia wasn't a concern. She felt she had to tell the doctor she'd been taking them so as to not delay her departure once she tested negative - but her 'cure' is now part of the data showing that antibiotics work on covid.
