Re: hpv virus (does it effect your immune system)
It is more likely that because your immune system is weak, the HPV has been able to become active. You should concentrate on boosting your immune system to help suppress the HPV virus.
A person can carry the HPV virus for many years without it being active. As far as the person you are having sex with, you have both been exposed. You are not passing it back and forth. Once you have the virus, you have it.
