It is amazing what we know about how the
HPV virus does it's thing yet we really can't stop it without a lot of collateral damage. When I first read how
HPV attacked my mouth I was shocked to find out the level of known detail and how smart the virus is at surviving. As Brain said our cells have like 2 guards. Guard #1 makes sure the cell has accumulated enough "good stuff" to reproduce another good cell and Guard #2 must get the OK from Guard #1 before he determines that he can give the final OK to reproduce. Now
HPV comes along and goes to Guard #1 and says forget your rules and listen to me...I say it's Ok to tell Guard #2 that you are ready to go and then the virus goes to Guard #2 and says regardless of what you think, it's OK to signal reproduction so the cell reproduces without being ready or good enough to do so.
Now that's the children's version.
