If there is indeed a "new COVID", where did it come from? It is demonstrably true, using "teh sCIenCe" that virus never mutate into more dangerous entities (and this is a good thing - or we'd all be dead now, including the viruses). So, is this another brand new strain, unassociated with the previous one? Did another pangolin have sex with another bat?

The best way to end disease on Earth would be to end governmental rule across the Earth. It's that simple (meaning uncomplicated, not meaning "easy to do").
