I don’t believe it does as much as the hosts defenses. This currently is not known.
This virus exponential growth will quickly reach saturation levels no matter what the starting dose is my thinking.
In this point I could be wrong. It is not currently known.
But the underlying point is the virus is the same virus and does not get “weaker”. Once you got it you got it.
A lot of people out there saying there of different “strains” and that it’s getting weaker or stronger. That the virus is getting weaker, or there are weaker variations. This just isn’t true from the data. Although all viruses mutate this one isn’t really to a degree that’s causing functional change.
