I think everyone has some parasitic worms in them, it sucks and is gross to think about but usually they're not enough to cause massive damage, but everyone should take ivermectin like once a year to clear them out, they do in third world countries, but covid weakens the immune system allowing the parasites to take over and it leads to death in some cases, this is why ivermectin is a good drug to use in many cases, now it does have side effects like stomach problems so this is why FDA wants to control it's use which I agree with, just to out and out deny it's usefulness shows evil on their part.
