> but in contrast to colds, we have no good tool to properly diagnose the exact illnesses

Isn't this the case with "colds" too? At least in practice.

Maybe it's my bad luck, or location-specific (Poland, EU) - but ever since I became a parent (and saw myself visiting doctors 10x as often as before), I've started to notice that, unless it's one of few very specific diseases, you just can't seem to get any diagnosis for a "cold" from a doctor. They'll prescribe you/your kid some meds or treatments, but nowhere in the conversation they say "you have ${specific illness}". No such information seems to show in medical documents either. If I ask, they always manage to deflect the question without even acknowledging it (I haven't tried to insist yet, I don't want to be rude to someone who's nice and helping me).

Is this because they genuinely don't know anything beyond "one of many pathogens that cause this group of symptoms", but it doesn't matter because they all respond to the same treatment options (or don't respond to anything, and you're just treating symptoms)? Or is there a practice of not giving such information to patients?
