“susceptible people” can die from anything. You have it completely wrong.
This Franken-virus started out as engineered... slightly more serious than a typical flu and after two years it is now back to normal cold status.
There is no cure for the common cold because cold viruses aka coronaviruses... evolve even more quickly than typical flu viruses. If you caught a cold last year... you are no less likely to catch a cold this year. If you had covid last year you are no less likely to get it this year.
If you did a good job of isolating yourself from others and did not catch Covid last year, then you are more likely to catch it this year because your immune system didn’t get much of a workout fighting off viruses and now it is weaker than it was. This is why children in third world countries tend to have stronger immune systems than coddled American children. This is also why Covid did not even make a blip in most African countries. Squaller, filth and nasty insects build stronger immune systems... as long as you don’t catch something really serious like typhoid, malaria, yellow fever, or some disease that is actually dangerous compared to Covid.
The worst-case scenario is if you got vaccinated and heaven forbid... boosted. In that case your immune system is completely screwed up and who knows what you might come down with. That is not to mention all the nasty injuries largely related to clotting problems directly attributable to the vaccines... such as heart attacks, strokes, and organ failure.
So sorry... everything you think you know is mostly wrong.
531 people died from Covid yesterday. How many from the common cold?
