At this point, anyone who actually goes to the hospital specifically to be treated for COVID is a fool.
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.
