Or is it a bacterial/viral infection causing the itchiness to propagate?

Another thing to keep in mind is our “animal past”, as a lot of evolution effects stem from that.
When you don’t have hands and something itches… you lick it. Just like animals do. And that has the effect of cleaning the wound and the salvia is mildly antiseptic as well.
