Can hpv be transmitted through saliva?

Possible, unlikely: It is most commonly transmitted by direct contact. Separating that from salivary transmission would be difficult, and the enzymes in saliva usually destroy many viruses (hiv is an example).

HPV and Saliva: Yes. But, remember that most of us are infected with a strain of hpv by age 26. This will be an interesting story to follow as medicine learns more about hpv; finds more and better tests to predict the cancers this virus can cause. And, now that there is the gardisil vaccine all at risk (all young adults) should get vaccinated.
