HPV is a virus, and as far as research goes, viruses are not caused by parasites.
However..
- It is my suspicion that the afflictive presence of those types of viruses may have something to do with parasites after all, although data in this regard is limited and somewhat "cloudy".
- I believe and almost know for a fact that HPV alone CANNOT cause cancer.
I believe you gave your friend good advice by telling her to avoid Antibiotics for now.
Her next move would much depend on her current health status, but she shouldn't lose time.
