Hi Rick...
My husband had stage 3 tonsil cancer last year, also from HPV. I've done a lot of research on HPV and I have learned that once your spouse has been exposed to the HPV, your spouse can not re-catch it. HPV can lay dormant for 20 + years. In most cases our bodies will catch the HPV and flush it out of our system (or distroy it) with in about 3 years of getting it. But in some people it won't.
There are many different types of HPV out there, but HPV 16 seems to have the most risk of becoming cancer. Woman can be tested for HPV, and should be tested every year (your wife should ask her GYN for this test as well as the PAP test).
For men, there is still no way of testing men for HPV, only the testing of the tumor itself. Most of the time HPV is passed from person to person via sexual contact (like I said before, it can take up to 20 years for it to show up on any tests), but there have been cases of people that have had HPV cancer that have never had sexual contact with anyone. I was told by a nurse that there are now studies being done to see if HPV can be passed from a person onto objects, such as toilet seats, and may be spread that way.
They are now saying that up to 90% of the population (here in the US) has been exposed to HPV. Of the tonsil cancers, only about 15% are thought be caused by HPV, most of them being non-smokers under the age of 55.
