Nope.
Generally, as viruses mutate, they become more contagious, but LESS lethal. Of course viruses adhere to random mutation (assuming they are naturally occurring viruses) and survival of the fittest rules. Therefore any mutation that keeps the host alive longer to spread more, would be advantageous. Any mutation that kills the host faster would eventually eliminate the virus.
The oldest human viruses are the most contagious and the least lethal. AAMOF, there are thousands of ancient human viruses that exist in all of us, but cause NO SYMPTOMS and pose no health risk... and now you know why.
The more you know.
But aren't measles, mumps, rubella, chicken pox naturally occuring viruses? Why didn't they mutate? Just trying to understand.
If you believe the Earth is 6000 yrs old and evolution is a myth, just give up on this topic. (that is not aimed at you personally... just a word to all readers)
The viruses you have just listed are 'newer' viruses in the evolutionary scheme of things. They are still dangerous.
Our species has been host to tens of thousands of viruses that have evolved with us over eons, and still exist, still infect us, are still very contagious, ... but have evolved long ago to not negatively affect the host in any way. Survival of the fittest works like that.
They do mutate within a pre-determined blueprint to which scientists do not understand.
maybe a lab-created virus acts differently and needs "new instructions" to get more lethal
The problem with a lab created virus is that it's a chimaera (hybrid). Chimaera aren't natural and therefore can't mutate without external (man assisted) interference.
Anyone who doubts this was a man-made virus need only to read this article. I've noticed that since I first found the article early on in the Covid scare they have added a disclaimer.

>"Chimaera aren't natural and therefore can't mutate without external (man assisted) interference."
Very good. You are absolutely correct. It is not sustainable outside of man's assistance. Now, consider micro-chimerism. The same set rules applies to it as well.
Quite right. I borrowed your well articulated statement above to answer TSE1's post below. I hope this is alright with you otherwise I will delete it.
