Also the very important Gillion article from the NHANES study, really told us tons abut who, and what age, with what behaviors, gets infections, and this study defined the demographics of who is getting this. There is a lot of meat in this paper. Bottom line 7% of us have an active oral HPV infection at any moment in time across all population types. However when you look at age, the number really changes that overall average with two peaks one in the forties and one in the 60 year old groups. The paper states (and this is obvious in most diseases), that this was expected, and that there was a distinct relationship with higher age to increases in infection. As we age, our immune systems become increasingly incompetent. Welcome to your golden years. So we get more of everything, HPV infections are just another thing on a really long list.
