But viruses spread in the real world not some hypothetical lab. In the real world as viruses become deadlier they tend to provoke a much larger response from governments and populations, both in terms of prevention and vaccines/cures/treatments. That's why there's a lot more money spent on potential HIV vaccines than on vaccines for the common cold. Being deadlier is a distinct disadvantage if you're a virus trying to survive for the long haul.
I doubt the top epidemiologists are spreading myths.
The "unusual" cases where covid is causing death might not be enough, no. The fact that it causes people to stay at home however could be.
Do any of them have names? (Either the viruses or the epidemiologists)
And that’s supposedly because… these common cold viruses were just too quick to kill their victims, at first?
But those viruses don't generally spread very fast because of their severity.
It’s also quite obvious, mechanistically: COVID doesn’t lose many infections by eventually killing the patient who, by then, is obviously sick and most often in the hospital. It gets 80%+ of retransmission even before symptoms appear, removing all evolutionary pressure from the later stages.
