Isolation only delays it
Sweden is one of only a few countries who seem to have done it right.
Yes it does, and that was my strategy.
It is understood that viruses evolve over time to become less lethal because more lethal viruses don't get as many chances to spread, so the evolutionary pressure is for viruses to mutate until they become less dangerous.
What I had hoped to achieve was to delay the onset of my catching the bug until it had worked it's way through the population and evolved into a less dangerous form.
I managed to go over a year after the outbreak before I finally caught it, (because someone brought it to my home) and for me it was quite miserable.
I have since caught this thing five times, and as I am typing this now, I am coming out of my fifth bout with this nasty bug.
This last round was relatively mild, but still unpleasant.
Did my strategy work? It would have worked great had I severed more of my contact with the rest of the population, but it is what it is.
But I don't blame people for trying to delay it. Delay may make the difference between life and death for some people.
