There is just no evidence of that. Smallpox virus did not lose deadliness over centuries, maybe millenia, of time. Nor did polio. Nor HIV.
This concept of more transmissible and less deadly is wishful thinking, probably intended to move a stock portfolio.
Smallpox is a DNA virus thus does not mutate at the rate of RNA viruses. Apples and oranges.
Polio is a RNA virus but the current strains show: No symptoms 72%, Minor illness 24%, Nonparalytic aseptic meningitis 1–5%, Paralytic poliomyelitis 0.1–0.5% in children. Old school Polio was much worse. It did the easier spread less virulent thing.
HIV is RNA also but the antiretrovirals have screwed up its evolutionary pressures.
Viruses select for 1) not killing the host so they can spread. 2) not making the host so sick they can not go around spreading it.
That simple. Is Pharma suspect in this mess... yes 100%.
Are you so wrong that you make Joy Behar look like a MENSA member? Yep, 100%.
That’s just what was said by a guest on the Lars Larsson show, he was interviewed because he had knowledge of epidemiology. I just relayed his message. Here is an article from zero hedge.com about the new variant not killing anyone (yet):
