Ivermectin is an antiparasitic drug that's been used for decades, mostly for things like river blindness and scabies. It's not exactly a miracle cure, but it's been studied for its antiviral properties too. Some research suggests it might have some effect on viruses like Zika and Dengue, which are also single-stranded RNA viruses. So, if it works on those, why wouldn't it work on COVID? It's not like the virus is that different from others in its family.
But here's the thing—just because something works on one virus doesn't mean it'll work on another. Viruses can be tricky, and even if they're in the same family, their structure and behavior can vary enough to make a drug ineffective. Plus, a lot of the studies on Ivermectin and COVID have been small, poorly designed, or even questionable. That doesn't mean it's useless, but it doesn't mean we should take it as a guaranteed solution either. Science is about evidence, not just "it would be weird if it didn't work."
