The problem is that people still get bacterial and viral pneumonia from other germs and people’s throats still close up when they get strep bad enough.
People also, especially if they have other conditions, can get dangerous blood pressure issues with a bad enough sinus infection. Kidneys can shut down if one gets food poisoning and gets dehydrated.
All these can be coded as Covid if a hospital wants the Covid cash.
True enough, but that's all the more reason to avoid going to a hospital for pretty much any reason if it can be avoided. And if the hospital wishes to "treat" for COVID after one has been admitted for some other reason, one should simply leave. The "treatment" one is likely to get in a hospital will kill you. The hospitals have absolutely no incentive to see that one gets well but plenty of incentive of putting one on a vent and killing you outright for that sweet, sweet government money.
