I saw a person talking about the mutations.
Mutations by chance and mutations for survival/fitness.
We are likely seeing the survival/fitness mutations.

If the population was not locked down, less virulent stains would have spread naturally thru the population achieving herd immunity. Instead, lockdowns have caused a natural selection of the more transmissible forms of Covid to survive.
here is the post..far above my knowledge level and no idea if warranted
“I think the original post title probably shouldn’t use the word “worst” as it is too subjective. That being said, I can tell you I am worried about this strain , B1.351, that is being called the South Africa strain. The one called UK isB.1.1.7. These strains seem to demonstrate that they are achieving dominance by outcompeting other strains quickly. Their mutations don’t appear to be carried on by chance and indicate increased transmission . Multiple colleagues are also worried. Hopefully the anxiety is unfounded.”

The following is a long and good read. It backs up what you posted:
How Iceland hammered COVID with science!
The tiny island nation brought huge scientific heft to its attempts to contain and study the coronavirus. Here’s what it learned.
