Be very careful in assuming that ozone will kill any type of virus anywhere in the human body. The physics don't work tht way. Only direct hit inside the cells will kill it. Ozone works so fast, you don't get any ozone into the cells themselves, only oxygen and peroxide.
Hyperbaric oxygen works well along with topical peroxide gel or peroxide sits baths.
There are some strains that are benign. HPV is the same virus that causes warts on the hands. He tested positive on culture for HPV16,17,22,26,28, 56. All agressive strains that cause cervical cancer. Because he feels fine and healthy, he doesn't seem to care that he can infect futue women.
